He doesn't really the mutation funny so much as remarkable. This may not have been the appropriate response, but when he wasn't in the confessional like everyone else that was left he mainly seemed freaked out.

Also, starting in the Mine episode, he was starting to make an effort to help Mike once he figured out the causes of his MPD. For instance, in the next episode, whenever Mike turns into someone else (ie Manitoba and Vito), he undoes whatever the trigger was. Even though he doesn't do a very good job at it, he tries to keep his MPD a secret under Mike's request as well.

Compare this to Scott (who, by the way, isn't listed yet) who takes advantage of Mike's MPD to blackmail him into doing everything he says, turns him into Vito against his will so he won't help Zoey, then knocks him out after he's done using him.
