Well we all have agreed what Jen has done was wrong, but honestly it shouldn't be in the rule book as strategy (imo). She knew she was leaving. I would do the same. And I really do believe in my heart that the things Dick was doing and saying finally got to her. She didn;t have to be nice and what not. And that depressed her = eating.
About Jen having to walk away. Why is a 44 year old man allowed to bully constantly, especially to someone half his age who really never did anything TO him. Just because of things he has heard her say or things she does. And you notice he picked the one person that people already didn't like (Nick because of the kiss thing, Daniele because of Nick). He did that intentionally so that he could belittle her, everyone would find it funny and join in, etc. Why should Jen have to walk away to someone like that? She lives there to. What people are saying is that she should have to lay in her room all day in a bubble. Thats not fair AT ALL. Why not lock Dick in a room, since he can't control himself.
Ummm Eric and Jess won't put up Dick/Daniele - final 4 dealio

Eric wants Zach out, then Amber, then Jameka. And he told Jess this as well.
