I just had a few thoughts. I notice that in some episodes when Justine is in a scene but not acting, she tends to look bored and extremely tense. And I do agree with the people who think that Mallory was often the butt of Alex's jokes. And I think that there was no point in having Nick on the show---it just made Mallory seem like nothing else than "Nick's girlfriend." Does anyone else agree?

I meant at a specific moment. She would have a line in the scene, but when she wasn't talking the tension was evident. Yes, it's hard (I'm a theater major at my school), but you have to look like you're in the moment. So, for example, if it's a happy moment, look happy...not tense.
