I have to say that I learn to appreciate Plankton episodes more as they come less often. Heck, this was only the second Plankton episode during season 9.2 (the first one being Company Picknick). Also, I was really afraid that, at the revealing scene, where Krabs was about to hand over the secret recipe, it would turn out that Krabs knew all along and that he was aware of Plantons scheme all the time. I'm SO glad his feelings were legit. Elsewise everything the episode had accomplished so far would be ruined. Glad they didn't go for a cheap ending but did go for a semi-sad ending.
