*nods* That really showed up in the arc second after this, following Queen of Fables, when they were mysteriously split in two, super-selves and alterego-selves. Not only did Plas' Eel-self go to a much darker place than you'd expect, Eel was self-aware enough to know he really did not want to be there.
During this run there was also much more effective usage of his powers and a lot more random reshapiness of Plas in the art backgrounds, very enjoyable. He had like a visual exclamation point for everything.
