Corrected entry: When Marissa shoots Trey in the Season 2 finale, the blood changes from shot to shot. When the bullet first hits his back, blood sprays and drips from the wound, and then later when he's slumped over unconscious, the wound is small with hardly any blood. The wound on his chest also has little blood but then in the next shot it's all over his white singlet.
Corrected entry: Ryan shows up late for dinner at the restaurant where Lindsay and Caleb are waiting for him because of "traffic". We later see Lindsay driving him home. Since Sandy, Kirsten and Seth were all occupied elsewhere and Lindsay was already at the restaurant, the only other option is that Ryan drove himself, but if this was the case, why would he need a ride home with Lindsay?
