I'm not quiet buying that they want us to believe Patty put a hit out on Tom. Sure, he's keeping something from her (at this point), but not enough to make her want him dead. I could only see it if he was keeping other things from her, and she was feeling paranoid/betrayed (Tom being the only one who's been loyal and stayed with her so long and all), but it just doesn't sit well with me, too obvious.
I am beliving Martin Short is evil. I got the feeling he wanted Joe to have the money, that's why he let Louis (Joe's dad) poison himself, despite that little scene with Joe pouring out the alcohol.
