Evan maxes his skills - again.
As a scientist, Evan thinks that he should be investigating the knowledge loss that he has experienced twice now.
He is sure that he has completed his goal twice before, but some of the information is not there. He almost feels as though it were a dream.
Of course, he had two tramatic incidents happen about the same time he forgot things. The first time was when he was almost electrocuted trying to fix the trash compactor. The second was when he automatically put on his thinking cap without thinking.
