It was really good for her character development. I was hoping the show would do more with her after that but she was basically forgotten about until Weirdmageddon, where she seemed to revert back to her old characterization. And I felt bad for her when her family went broke
Yeah it was bummer to see Pacifica going back to her old self but the ending with her making a present for the twins made me happy. They didn't completely forget her development. Her parents were trash, so they deserved to lose their money but not Pacifica.
I don't get why they built up her character so much in that episode and did nothing else with it. I suspected she'd come back at some point during the Ford episodes but it never happened. RIP Dipifica.
