Oh so she did know that place was currently the most dangerous it is all year. I always hate when stuff like this is part of your first impression of a character who is clearly going to be one of the friends later on. You can't really make up for this kind of thing. She could save Coco's life a dozen times, I'd still have trouble forgetting the time she could've gotten Coco killed because she was being a bitch for no good reason.
