Hello Snavel del Snuit.
Yes, I did see the finale. In an episode before, Izzie told George he could stay, that she didn't love him like that, that the "encounter" had meant nothing to her, etc. Then in the finale---she's in love with him. So yeah, I agree---she's not clear on the whole thing.
I'm anxious for season 4.
OH---maybe I should say, SPOILER:
You know the girl in the bar who tried to pick up Derek is Meredith's half sister? Well, that would just be TOO much if he started dating her after all the other family members who have been jerks to Meredith. I HOPE he does not.
If Derek does that, I will be ready for Meredith to find someone else. I really want her to find true love before the show ends.
