I wasn't watching Marty the first time round, but from what I heard she's always been a cruel, nasty bitch who cared most about herself, though I think she had decent moments from what people have said. The psycho part certainly is new, though.

ITA about Clint! I always liked him and felt so bad for him when Nora cheated on him with Bo but now I just hate all three of them.

Marty was never a cruel,nasty bitch.In the beginning,she was young,alone and had a lot of issues that made her make the wrong decisions.Her parents were dead and the aunt who was supposed to be her guardian had more or less abandoned her as soon as she turned 18,so she became a bit of a wild child,resulting in the gang rape.
She calmed down and eventually became one of the show's top heroines.
It's hard to recognize the old Marty in this pathetic psychotic.

Marty is acting like how she would have eventually morphed into had she not been redeemed by her rape. I liked her bitchy side with Natalie but Bonkers Marty makes me really uncomfortable to watch.

From the time Marty returned, you could see she had it in her to be a real bitch. I tolerated her for awhile, but I really couldn't stand her. She's been delusional about Cole from the beginning and now she's gone nuts. Maybe that's why she didn't see how psycho and violent both Cole and Hannah were.

Marty's been bitchy for a LONG time, though.
