Yeah, I agree that Mark's sister going to Cobel wasn't well justified by the story, but I feel that Cobel's turnabout was a little more justified yet not completely. I think they emphasized how wrongly Cobel was treated by Lumon in many ways, which would cause most people purely motivated by corporate loyalty to sour on the company. The problem is that we're dealing with religious fanaticism in addition to corporate loyalty, so I think it would probably take even more than she went through to get someone to turn against their religion. But who knows, I give them the benefit of the doubt on that one for now. I agree with people who say that season 2 hasn't been as fresh and satisfying as season 1, but I'm still liking the show.
