I don't hate Petra. I just get tired of seeing her. Even though I admit that she starts most of the fun (like she was the one that started the threesome on Sunday), I wouldn't mind if she left. Then again, with the exception of Ann, Niki and the new girl in Tver and Boobie, I actually like if everybody left.
At the end of the day we all like who we like and dislike who we dislike. Sometimes it baffles me how much people like Sonia and Anna but at the end of the day, I don't really care one way or another.
