I chose Wrecked because although seeing Tara brain sucked and her leaving Willow were very sad moments, I never had any doubt that everything would be ok eventually. But in Wrecked (although the magic = drugs storyline made NO sense at all) seeing Willow hit rock bottom was really sad, and seeing Tara not be there for her was the saddest thing of all
