Willow hurt him and that it was a horrible thing to do to anybody--let alone family. That is admitting it was wrong.
Drew sucks. No ifs, ands or buts about it. I'm more thrown by the line: You don't know anything about Willow and I! And then to go see her and then start calling. He's smug and entitled. I guess he figures, well--the secret is out, so nothing stopping us from being together or having round 2.
And I just don't care about Michael's tiny box of pain because he is just getting a hefty dose of karma. Chase was his best friend and that didn't stop him from taking Willow to bed. So you know what, you lose 'em how you get 'em. She cheated on Chase with Michael and now he is on the receiving end of that.
And the more that I think about Michael did this to Morgan when he was married to Kiki. The boomerang known as karma is way late--but it has finally popped him upside the head.
