Since when does anyone have to be "free" to dump someone else? Cris seemed like a total jerk in that scene. I mean really, who says that? And why would he say that at a time like this? Marisa is going through such a hard time and then after talking to Sara, Cris decides to put a possible break-up in Marisa's lap as if he isn't man enough to do it himself. If he thinks he failed her and he's listening to Sara and his mother about how Marisa is "crazy" now, then he should just go ahead and dump her. He's a total fool.
I like the actor who plays Victor too. The character is an idiot, but he plays him really well and he's pretty funny most of the time.
