Katherine's Narration: “We are the culmination of our past, and the bane of our future.”
The episode opens as Katherine and Molly arrive at the F.I.N base near Bikini Bottom, both dressed in their costumes.
"Ladies, welcome," Payne greeted.
"So... about our talk? Me using Mikey Merlin and Slug..." Katherine said, hopeful.
"I've granted you the permission," Payne said.
"What's the catch here?" Molly questioned.
"No catch. On your ends, anyway," Payne hinted.
At that moment, Mikey Merlin and Sebastian Slug arrive in the assignment room, being escorted by multiple agents.
"Hello, kid. It's been a while," Mikey teased.
"You agreed to help me?" Katherine questioned to Mikey.
"Only because of the deal I was offered," Mikey said.
"What deal was that?" Katherine questioned.
"F.I.N will set up a visit for Mr. Merlin with his daughter, who was taken into foster care," Payne revealed.
"Oh my god. I guess you jumped at any opportunity to be able to see your daughter. After all, losing her and your wife was the main reason you tried to kill me last year," Katherine noted.
"Fun times," Mikey cockily smiled.
Katherine rolled her eyes.
"And what about you?" Molly asked to Slug.
"Last year I almost hurt your friend, Miss Appear. I want to make up for that," Slug said, as he looked at Katherine.
"And can you control yourself now? I mean... control when you become that beast?" Katherine asked.
"F.I.N's been working with me on. You and Pink Arrow getting me into their custody was the best thing that could of ever happened to me," Slug said.
"He's made excellent progress. I can assure you that," Payne said to Katherine.
"I only become the Sinister Slug when excited. Whether those emotions are angry or happy," Slug said.
"And after? How do you cool down? How do you become Sebastian?" Molly asked.
"I repress that anger. It's proven to work," Slug said, nodding.
"So, what's that catch again? Because I'm sure you're not just gonna let Killer M out into the loose like this," Molly said.
"Both men agreed to a chip implanted in their head. There's a kill-switch that goes off in an instant if they do not return here willingly after this mission is done," Payne said.
"Sounds good," Katherine said, glaring at Mikey.
"So, about the mission detail?" Mikey questioned.
"Dirty Dan has a jet waiting for me as we speak near Bikini Bottom Forests. I'm going to board the jet, which will take me to Koi Island," Katherine started.
"At that point, Kid Appear, Mikey, and Slug will follow discreetly in a F.I.N Quickjet. A tracker has been placed on Katherine. You'll use this tracking device to pinpoint her location on the island," Payne finished.
At that moment, Katherine got a text.
"Show time," Katherine read.
"Dirty Dan?" Molly asked.
"He's not gonna wait any longer. Time for me to get going," Katherine said.
"Be safe. We'll be right behind you," Molly said, as the two hugged.
Katherine took off.
"So, who's flying our jet?" Molly asked.
"That would be me!" Clemmons said.
"Clemmons here will fly you all," Payne said.
At the castle on Koi Island, we see the heroes locked up in the dungeon. All of their hands tied in binds.
"Well this sucks," Bonnie said, frustrated.
"Tell me about it," Analise said.
"Once we're free, Dirty Dan and his band of sorry losers will pay, trust me on that," Tim said.
"Why? Because you're the oh-so-great Barnacle Boy?" Bonnie questioned, sarcastically.
"Yeah, something like that," Tim said, rolling his eyes.
"I hear someone coming," Adam said.
At that moment, two guards let Vivian into the dungeon, as she's seen carrying a gun.
"What's the gun for?" Analise asked.
"In case any of you make any sudden moves," Vivian said, pointing at them. "Let's not jump the gun though," she said, lowering it.
"Why are you here, you two faced witch?" Bonnie questioned.
"To let you all know that Kathy is on her way!" Vivian said, playfully.
"Yeah, she is. She's coming to save us," Analise said.
"Oh no, she's not coming for the likes of you four," Vivian said.
"What do you mean?" Tim asked.
"Katherine's on her way to see Dan - and rejoin his mission," Vivian said.
"Katherine would NEVER!" Adam spoke out.
"Vivian, you're insane if you think that's what's gonna happen," Analise said.
"It's part of the deal, kiddies," Vivian said.
"What deal?" Tim asked.
"Dirty Dan told Katherine that he will spare your lives if she agrees to undergo the serum again and work with him," Vivian revealed.
"I don't care what terms she may have told him that she accepted. She'll never do it. She'll have backup to save us. We have very powerful allies," Analise said.
"If she shows up on this island with even one person by her side, the four of you will be murdered on the spot," Vivian told them. "She's not gonna risk that."
One of the guards enters the room.
"What is it?" Vivian asked.
"A message from Dan. She's here," the guard said.
Vivian turned around, evilly smiling at the heroes.
"One day... I'm gonna slap that smile off your smile," Analise threatened.
"Ya know, I liked Katherine's fire friend better than the rest of you," Vivian said, as she and the guard left.
"Fire friend?" Bonnie questioned.
"Captain Magma. I kinda wish he was here right now," Analise said.
The scene shifts, as we see Dirty Dan, Pinhead Larry, Spin and Vivian outside in the front yard of the castle.
Katherine approaches, having been dropped off by one of Dan's minions.
"Enjoy your ride here?" Dan asked.
"The guy was kinda shaky on the wheel, but otherwise it was fine," Katherine said.
"I'm serious about wanting this to be completely your choice - joining me again," Dan said.
"How about you let my friends go and see what my choice is then?" Katherine asked, sarcastically.
"You're cute, but no," Dan said, smirking.
"Shall we get on with it?" Vivian asked.
"Oh Vivian, always standing in the shadow of someone more powerful than you," Katherine sniped.
"I just don't like to get my hands too dirty. It's a virtue," Vivian said, rolling her eyes.
"As much as I'm enjoying this reunion - the show must go on," Dan said. "Come."
Katherine followed Dan and the others into the castle, as she sighed.
The scene shifts, as we see the F.I.N Quickjet quietly land on Koi Island. Molly had used her powers to make the jet invisible.
"Thanks to you Kid Appear, I'm sure we were not detected," Clemmons said.
"Good," Molly said, as she unbuckled.
Molly, Mikey, and Slug all got off the jet.
"Coming?" Molly asked to Clemmons.
"Someone needs to stay and guard this thing. It's our only way off the island," Clemmons said.
"He's right," Mikey said.
Molly, Mikey, and Slug begin walking as Mikey reads over the tracker.
"Right. The directions to Katherine's location," Molly said.
"Who is she to you? Katherine, I mean. Sister?" Mikey asked Molly.
"I bet you'd like to know," Molly said.
"I'm not that guy anymore. I've had time to... cool down, while in F.I.N custody. Much like our angry friend here," Mikey said, patting Slug's shoulder.
"Hey, I don't like touching," Slug told him.
"Sorry," Mikey said.
"You haven't changed. You just wanna see your daughter again," Molly said.
"My daughter is why I changed. I thought of her, day after day while imprisoned. What she'd think of me and everything I've done," Mikey said "I've got a lot of blood dripping off my name. Pain, hurt, and blood."
"Well, maybe your daughter will hear one day about how you helped Miss Appear save her loved ones," Molly said, softening toward him. "Maybe one day, that will give her comfort... and hope - for what you might've been."
Mikey nodded, as he went into deep thought.
Inside the castle, we see Dan and Katherine walking down the halls together.
"Where did the others get off to?" Katherine questioned.
"I asked them to give us a minute alone, as I walk you to your injection site," Dan said.
"Made yourself a little nest inside this castle, huh?" Katherine questioned.
"Legend says this castle used to belong to a mystical coven of witches. It was eventually inherited by the group known as the Heckfire Clan," Dan told her.
"And now you have it all to yourself. I mean, you can't return to that underground bunker in Bikini Bottom," Katherine said, teasingly.
"Once I have the city, I can do whatever I want in it. And it'll be all thanks to you - or are you going back on our agreement?" Dan questioned.
"No, I'm not backing out," Katherine said.
"Good. You'll be Crosskill once more," Dan said.
"We'll see about that," Katherine whispered under her breath.
"What was that?" Dan asked.
"No, I just said that it sounds like a plan," Katherine lied.
"Yes it does," Dan said, smiling.
The scene shifts, as we see Molly, Mikey, and Slug approaching the castle's entrance.
"There it is up ahead," Mikey said.
"There are two guards out front," Molly said, as the three hid behind a tree.
"I'll cut through them," Mikey said, reaching for a sword.
"No! You'll draw attention," Molly said.
"I thought this was gonna be a little bit fun," Mikey said. "I'm disappointed."
"By all means, stay disappointed then," Molly said, rolling her eyes.
"What's the plan here?" Slug asked.
"I'm gonna mind blast them," Molly said.
Molly used her telepathy to get inside the guards' heads, knocking them out from afar with a mind blast.
The two guards silently fell to the ground.
"Alright, now let's go," Molly said, as the three approached the entrance.
"We need the layout of this place - and to know where exactly Katherine's allies are being held," Mikey said.
"I guess we should leave that to the telepath," Slug said.
"Right..." Molly said.
Molly bent down as she touched the head of one of the guards. She used her telepathy to get an idea of the castle's layout and the location of Analise, Tim, Bonnie, and Adam.
"Got what we need?" Mikey asked.
"Oh yeah," Molly said, finishing. "Both of you take my hand, we're going invisible."
Meanwhile, Katherine and Dirty Dan enter a medical room within the castle.
"This medbay looks like it's out of the stone age," Katherine said.
"Relax, take a seat. Vivian will be arriving with the concoction," Dan said.
Katherine sat in a dusty chair.
"Ya know, I don't get it," Katherine said.
"Don't get what?" Dan asked.
"Why you're so dead set on Bikini Bottom. What is it that you want from that place?" Katherine asked.
"Symbolism, justice," Dan said.
"What?" Katherine questioned.
"The city my trash father was once mayor of... I get to take over and run for myself. Poetic justice, my dear," Dan explained.
"Your father?" Katherine questioned.
"My real father - the late Martin Rogers," Dan revealed to her.
"You're lying," Katherine said, her eyes widening.
"Your friends already know the truth. Even Analise," Dan said.
"She's... your sister. If this is true," Katherine said, in shock.
"It's true. Martin Rogers couldn't be with my mother. Both were young kids from different social sectors. He came from a wealthy family, my mother was from a rougher side of the tracks," Dan explained.
"So he abandoned you... or at least his family forced him to," Katherine said.
"Doesn't matter. Either way, my mother had to raise me alone," Dan said.
"You're pissed, angry. I get it. I have daddy issues as well, but it's no excuse to cause pain and sorrow," Katherine told him.
"I'm way past a good 'talking-to'," Dan said.
"Obviously," Katherine said. "Look, Analise is your sister. I loved her for the better part of two years. Don't do this - for Analise's sake."
"Don't do what exactly? After all, we had a deal," Dan said.
"You don't have to remain this person. You can change, and you can have a relationship with your sister. If you continue this, Analise will never love you," Katherine told him.
"Analise has already stabbed me in the back - by refusing to join me," Dan said.
"So, it bothers you that she has morals, convictions, ethics - " Katherine started.
" - ENOUGH!" Dan shouted. "We had a deal. Talking about me and the aspects of my life wasn't a part of that deal."
At that moment, Spin arrived in the room, carrying a syringe in hand.
"It's done. Compliments of Vivian," Spin said, smiling.
"Alright, I'll let you handle this," Dan said.
"Where are you going?" Spin asked.
"To check on our prisoners," Dan said.
"You better be getting ready to release them," Katherine threatened.
Dan smiled, as he walked out.
"Loyal to the end, Spin?" Katherine questioned.
"Soon enough, you'll be singing that tune as well," Spin replied.
"Soon enough, I'll be brainwashed. You on the other hand... chose to do this. Chose to align yourself with someone like him!" Katherine argued.
"It's no business of yours what I chose to do... and why," Spin said.
"Now, time for injection," Spin said, as he readied the syringe.
"Or not!" Katherine said, smiling.
Suddenly, Molly turned visible, as she appeared in the room. She quickly levitated the syringe out of Spin's hand.
"This is a breach of contract!" Spin said, as he tried to disorient Molly.
The effects of his powers seemed to have no effect.
"Sorry, Spin," Molly said, pushing her hair out of the way to show a small device behind her ear. "New device designed by F.I.N. Nullifies your meta abilties."
Spin's eyes widen in fear.
Both Molly and Katherine shoot a telekinetic blast at Spin, which slams him into the wall.
"Your powers are back!" Molly said.
"Just in time, too," Katherine said.
"Agreed," Molly replied.
"Well, Spin's down!" Katherine said, running to hug Molly. "But we need to get to Dan next."
"Sorry if we were cutting it a little close," Molly said.
"Oh that's fine. Let's just get going!" Katherine said, as the two rushed off.
The scene shifts, as we see the heroes still locked up in the dungeon.
"I really hope Katherine comes through," Bonnie said.
"She will," Analise said.
"Yeah, there's no way she'd get back into bed with Dirty Dan. She'll have some kind of contingency plan, I'm sure of it," Adam said.
Suddenly, the heroes saw the two guards outside of the door being sliced with a sword.
"HOLY SHIT!" Bonnie yelled, as blood splattered.
"There's your contingency!" Tim joked to Adam.
"Uh, nice swordsmanship, but the bloody bodies freak me out," Slug said.
"I'm sure you've had your fill of skeletons hanging out the closet. Especially when you're that thing," Mikey said, as he snatched the keys off one of the guards' body.
Mikey unlocked the dungeon door, as Tim, Analise, Bonnie and Adam flooded out.
"What the HELL? Mikey, what are you doing here?" Analise questioned.
"The famous Killer M... well I'll be damned," Tim said, shocked.
"I believe the word you're looking for is infamous," Mikey teased.
"I ask again, what the HELL are you doing here?" Analise reiterrated.
"Relax girly. I'm on the side of the angels this time," Mikey said, as he began to cut the shackles off of the heroes.
"We're with F.I.N... and Katherine," Slug said.
"Wait... Slug?" Analise questioned.
"I'm here to make amends for my past," Slug said.
"I believe you," Analise said, nodding. "But... I don't trust that thing," Analise stressed.
At that moment, dozens of Snake Eyes members showed up with guns, storming both ends of the hallway.
"Wanna reconsider that?" Slug asked her.
Analise stared at him in panic. "Whatever man, do your thing," Analise said.
Slug transformed into his beast side, growing large and more angry.
Slug launched at the Snake Eyes, as the other heroes did the same.
Mikey cut through most of their guns, as Tim and Analise used their martial arts to take them down.
Around the corner, Dirty Dan and Pinhead Larry had caught up with the commotion.
"Katherine played us! None of her friends leave here alive. Neither does she," Dan ordered to Pinhead.
"And what about that beast?" Pinhead questioned.
"Size it down, NOW!" Dan ordered.
As the Sinister Slug rampaged through the castle halls, tearing apart Dan's soldiers, Pinhead surprised the beast with a punch from behind.
Slug went flying through a wall.
"Let's see what you're made of, you mindless monstrosity!" Pinhead insulted.
Slug roared, as it jumped at Pinhead.
Pinhead punched the creature up to the ceiling, creating large cracks.
As the two continued fighting, the castle began to shake.
Bonnie and Adam were seen approaching the scene, as they stared at each other in fear.
"They're fighting is gonna tear the foundation of this building!" Bonnie said.
"I know!" Adam replied.
Finally, Slug swatted Pinhead with his tail, as Pinhead went flying out of a glass window. Slug roared, as he took off to find more enemies.
Bonnie and Adam felt the heart beating fast as the creature flashed right past them.
"Oh god, I think I literally shitted myself!" Adam said.
"No one needed to know that!" Bonnie said. "And Pinhead's not getting away!"
Bonnie began to run off.
"Bonnie, wait!" Adam yelled.
"NO TIME!" Bonnie said, as she jumped out the large window.
On the other side of the castle, Vivian was running through the halls with a bag in hand.
"WHERE DO YOU THINK YOU'RE GOING?" Katherine questioned, jumping out in front of her at the end of the hall.
"Katherine... hi," Vivian said, nervously.
"Sit the getaway bag down, Vivian. You're not going anywhere," Katherine said.
"Katherine!" Molly said, arriving at the scene.
"Molly, I got this. Go help our friend!" Katherine said.
Molly ran off.
Vivian stared at Katherine, who reciprocated just as intensely.
"I literally can't believe you," Katherine said.
"I'm not a good person. I admit to that," Vivian said.
"Don't try and feed me some pathetic narrative, Vivian! About your troubled past and abuse at the hands of George. I DON'T CARE. Because that has nothing to do with the choices you make today," Katherine said.
"I know that," Vivian said.
"You tried to strip me of my autonomy. JUST so that I could do your bidding. So I could grab power for YOU," Katherine said.
"Everyone wants power, Katherine," Vivian said.
"But why do you want it so badly? That you'd go to all these extreme lengths? What would my mother think of you? About what you did to me?" Katherine questioned.
"She's not around for us to ask," Vivian said.
"SHUT UP! I am SO tired of you!" Katherine said.
"Yeah, well I'm getting pretty tired of you too!" Vivian replied.
"This is it for you, Vivian," Katherine said, as she squeezed her hand.
"What do you mean?" Vivian questioned, as her heart raced.
"I'm letting you go right now, because I need to get to Dirty Dan. But, there's a condition. You never return," Katherine said.
"Excuse me?" Vivian questioned.
"You NEVER return to Bikini Bottom - and I never hear from you again. If you do not comply, I will kill you. Once and for all," Katherine threatened.
"You don't sound like yourself, niece. Something's not right with you. You're slipping," Vivian said.
"You did this. You drove me to this!" Katherine said.
"To be a killer? Like your cousin?" Vivian questioned.
"Billy is not my damn cousin," Katherine replied.
"Certainly a lot of similarities, even though. Or did you forget all the crime you committed as Crosskill?" Vivian said, toying with her.
"I'll never forget. But it wasn't me. Once again, that was YOU. When this all started, Dan said he'd make me realize who my greatest enemy was. He was trying to say that my greatest enemy was me - as Crosskill. Now I'm realizing the reality of it all. My greatest enemy... is you," Katherine told her.
Vivian sighed in frustration.
"You've been behind EVERYTHING. Had a hand in all of the craziness that has happened to me these past few years. It ends today. I will kill you if I ever see you again," Katherine threatened.
"Maybe... maybe in another time, or place, or universe... maybe we could of been actual family," Vivian said, softly and tearfully.
"Maybe," Katherine said, shedding a single tear. "Go."
Vivian ran off, as Katherine stood alone in deep thought.
Outside, Dirty Dan and Pinhead Larry had escaped into the island's forest.
"That beast was pretty daunting, I have to admit," Pinhead said, limping a bit.
"It was powerful enough to leave you with bruises from the fall out the window," Dan said.
"I know," Pinhead said.
"That's why we had to leave. That beast is gonna tear through everyone. We've lost this round... or yet maybe..." Dan said, in deep thought.
"If you can't have Bikini Bottom..." Pinhead started.
"... No one can," Dan said, smiling.
"STOP!" a voice was heard.
Bonnie appeared, running behind the two.
"Find another pathway, while I handle this one!" Pinhead said.
"You sure?" Dan asked.
"Go!" Pinhead said.
Dan took off.
"What are you without that sonic collar of yours?" Pinhead questioned, teasingly.
"I'm determined as HELL to find out!" Bonnie said, racing toward him.
Pinhead used his super strength to quickly swat Bonnie out of the way.
Bonnie went flying against a tree, groaning in pain as she hit the ground.
"You were a FOOL to come after me! Just like you've always been!" Pinhead said, walking over to her.
"I'm not afraid of you! I don't fear anyone!" Bonnie said, shakily trying to lift up.
"Where you're going, fear won't be a possibility anyway. I'm sending you straight to heaven, hero," Pinhead threatened, as he was ready to kill her with his bare hands.
Something in Bonnie snapped, as she jumped up and unbelievably released a massive sonic scream at Pinhead Larry. The piercing scream sent him flying back, while also tearing down nearby trees.
"... What the hell?" Bonnie questioned, in disbelief that she'd released a natural sonic scream.
Bonnie ran to Pinhead's body.
"Pinhead! Pinhead!" Bonnie shouted.
Bonnie felt for a pulse, to no avail.
"Oh my god..." Bonnie said, realizing that she murdered Pinhead Larry.
The scene shifts, as we see Vivian exiting the castle through a back door. Mikey appears in front of her, smiling.
"I knew I'd find you coming out here," Mikey said.
"Mikey... Katherine let me go. Get out of my way," Vivian said.
"How are you going to get off this island?" Mikey questioned.
"Doesn't matter!" Vivian said.
"Take me with you," Mikey said.
"Why should I do that?" Vivian questioned.
"You owe me, remember? Be thankful I focused on trying to kill Katherine all last year instead of you," Mikey said.
"I suppose that's true..." Vivian said.
"F.I.N implanted something in my head. I need you to quickly cut it out," Mikey said, pulling out a pair of scissors.
Meanwhile, Dan is seen running through the forest, as an invisible force knocks him to the ground.
Dan tumbles across the forest floor, as his gun falls out of his pocket.
As he gets to his feet, Katherine turns visible. She uses her telekinesis to levitate the gun into her hands. Katherine aims the gun at him.
"Well hello there, Miss Appear," Dan said, putting his hands up.
"Put your hands down, I'm no cop," Katherine said, looking at him with great intensity.
"Clearly, but I don't want you to misinterpret my body language," Dan said, putting his hands down.
"Oh there's nothing to misinterpret about you. You're a power hungry, abusive, piece of trash with serious daddy issues. You think you get to take that out on the rest of the world? Well, you don't," Katherine said.
"Isn't that what you did? As Crosskill? That serum revealed the real you. The little girl spiraling out of control - yearning for daddy to come and hug her," Dan said.
"Don't! Don't you dare psychoanalyze me. Not when you're the one who's the psycho!" Katherine said.
"What are you doing, Katherine? We both know you're not gonna pull that trigger," Dan said.
Katherine cocked the gun. "Wanna bet?"
Dirty Dan gulped.
"You say you loved my sister, right? You're not gonna take Analise's brother away from her," Dan said.
"She doesn't want you! None of us do," Katherine said.
"You're no killer, you're a hero aren't you? Or so you've claimed," Dan stated.
"Even heroes reached their breaking point. Two years ago, my best friend was murdered, setting me on a path I could of never imagined. While I've grown immensely, I have also suffered - time and time again from absolute maniacs. Latest in the line - YOU. All of this ends now," Katherine said, as her fingers tightened on the trigger.
"If you kill me, Bikini Bottom goes too," Dan said.
"Excuse me?" Katherine questioned.
"You heard me. Under my clothing, I'm wearing a series of wires linking to multiple bombs set up underneath Bikini Bottom," Dan revealed.
"You're lying!" Katherine said.
"I'm not! You shoot me, and these wires trigger an explosion that will wreck Bikini Bottom," Dan said.
"This is just another mind game! Every one of my enemies has employed vicious mind games on me over the years. I refuse to let my mind ever be controlled again! This is the culmination!" Katherine stated, reaching her snapping point.
"Katherine, WAIT!" Dan yelled.
Katherine pulled the trigger, shooting him three times.
Dan fell to the forest ground, bleeding out profusely.
Katherine was shaken, as she realized that she had killed someone.
Analise, Molly, Tim, Adam, Bonnie, and Slug appeared, as they saw the horrific scene.
Katherine turned around towards them.
"... Analise..." Katherine said, softly.
"Come here," Analise said, as she pulled Katherine into her arms.
Katherine and Analise embraced for a long time, while the others checked out Dan's body.
"Katherine, what happened?" Tim asked.
"I... just snapped. I shot him, even after he suggested that doing so would cause explosions in Bikini Bottom," Katherine revealed to them.
Tim cut open Dan's shirt, squicked out by the blood. Under Dan's shirt, the heroes saw a small machine taped to his check, with wires extending out of it.
"Oh my god..." Katherine said, shocked.
"We need to get back to the city, NOW!" Tim said.
"A F.I.N Quickjet is here on the island," Molly said.
"Yeah, follow us," Slug said, back in his normal form.
Katherine's Ending Narration: “I realize now that I wanted to disappear. To get so lost that nobody ever found me. To go so far away that I'd never be able to make my way home again. But I have no idea why. I guess, you sometimes think you want to disappear, but all you really want is to be found.”
The F.I.N Quickjet arrives back in Bikini Bottom around an hour later, as the city appears to be in shambles.
Clemmons lands the quickjet on the streets, as the Katherine and the rest of the heroes hurry outside.
Team Appear sees ambulances, fire trucks, and police cars all over. They notice destroyed buildings, cars, and streets. All over the city, people were bleeding out and in need of dire medical attention.
"What... what have I done?" Katherine questioned, as she felt guilty.
As the team continues through the ruined city, they run into Detweiler on the streets.
"DETWEILER! What happened?" Analise called out.
"I should be asking ALL OF YOU!" Detweiler said, angrily. "Multiple explosions went off about fifty minutes ago, ALL over the city."
"This was... this was my fault," Katherine said, as her heart sank.
"No! Don't blame yourself! This was DAN!" Analise said to her.
"We need to help these people," Bonnie said,
"You all need to steer clear and let the paramedics and fire fighters do their job!" Detweiler siad.
Suddenly, Katherine's arms began to disappear.
"... What's happening?" Katherine questioned.
Everyone looked over to her.
"Katherine, what's wrong?!?" Molly questioned.
"I'm not doing this on purpose!" Katherine said, as her entire body began to disappear.
"KATHERINE!" Analise yelled, in terror.
Katherine completely disappeared.
"Katherine...?" Tim questioned.
"KATHERINE!" Analise yelled out.
Molly reached her hand out in the area Katherine was standing at.
"She's gone," Molly whispered. "Katherine's gone."
THE.END (of Season 4)
Mikey Merlin and Sinister Slug both reappear, last being seen during early Season 3.
Bonnie seemingly produces a natural sonic scream, without the aid of her sonic device. She unwittingly murders Pinhead Larry.
Katherine shoots and kills Dirty Dan, which triggers massive explosions across Bikini Bottom.
Katherine seemingly disappears/vanishes. It is unknown what happened to her.
