I have to agree that Croc's role and results make sense. Croc also hinted before at being Kakashi (remember when he said "I am Naruto's teacher"), so I believe him. I don't know why he has been so lurky, but my suspicion of him is reduced.
I think that the best lead we have is Pie, even though he has acted pro-town. It would at least give us info on the theme split, as we know his character is on the evil side of things.
BearMan has contributed to town but I think he is worth the interrogation, and Skittlez is suspicious but he does seem receptive of interrogation.
If they aren't obvious vital power roles, I think both of them should claim character.
