I am a bit behind, but I have two thoughts about this show:
I am beginning to wonder if there will be another murder mystery, with StefanO being the victim. Maybe not. But with so many people really angry with him and saying that he will pay for what he did, it just seems that the formula is materializing.
That said, I know that there is currently a need for a villain, especially if something ends up happening to StefanO. Please please PLEASE don't let Chad go to the dark side. I love that he is passionate and that his anger gets the best of him from time to time, but to me, that's part of what makes him so likable. He makes mistakes, but is a genuinely good guy. And he isn't one to betray his best friend. So, I hope that Chad is either playing Kate, or he's making a mistake and realizes it quickly. I hope.
