I liked the show on Monday, but unfortunately I saw the twist coming at the very beginning. When the brother had the body in the garage it didn't even occur to me that it might be the mom, I just figured it was the sister. That plus the fact that the sister had the scar and mentioned a car accident and it was a short leap to the conclusion.
I am interested to see what happens with Ariel and whether she really went on the ski trip or something else happened. I have to say that the girl who plays Ariel does a very good angry teen. My son gets the same attitude when he feels that he has been wronged. Of course it NEVER has anything to do with HIS actions.
