I sure wish Denny were still alive, I miss him so. I get upset at Izzie because she was supposedly so in love with him but look at what she did with George. Now she claims to be in love with George, I just think shes confused. I think that ever since Denny walked by her and she felt his presence, she probably feels like she can try to move on. Since she and George are best friends, I think she confusing the love she feels for him as a friend. Honestly I kind of started hating that whole storyline when she got all weak and attached like she did with Denny. It made her character less genuine to me. Then there was the whole Alex situation. She supposedly loved him but he turned out to be a total ass and ruined the relationship but I think he's still in love with her and Izzie just needs to realize she still feels the same way for him. If Izzie can't be with Denny then I want her with Alex!
