Marley's so-called "friends" (i.e.: the other N.D. "girls") completely suck ass. I really don't like Grease, but I know what that song is about and for - everybody does, just listen to the words. And they went and did the whole thing. With someone they hate. Against someone they like. It's also completely unbelievable that any of them would agree to have any involvement with Kitty in the first place, let alone have a sleepover. As with most episodes lately, they seem to just throw in unexplained out-of-character events to try and sleight-of-hand their way to some point they're trying to get to or make.
I'm starting to care less and less about this show.
