What is happening to Izzy?

I had heard in other discussions that she was going to be getting a brain tumor possibly. They were saying that because of the comments katherine heigle made about her character not getting good enough material that they were going to kill her off the show. I don't know if that is true or not. I figure they could write a brain tumor in the story line and then if they decide not to fire her then they could let meredith and derek save her with their new brain tumor fighting thing. So my guess is it is a brain tumor, although i'm not sure why she would be able to feel denny. i guess it is just all in her head.

I hope that they don't take Izzy out of the show. The last few weeks it has been really weird just watching her. She is a great actress though, isn't she? I don't think the show would seem the same without her!

i don't think reviving again that denny issue on grey's was a good thing. i mean, c'mon, that's so seasons ago. can't they think of anything better about izzie's character? i love izzie, too but this thing, her talking to a denny ghost, it's just not a good idea. grey's anatomy isn't a paranormal show, it's a medical show so earth calling grey's anatomy writers. but, i don't want katherine heigl out of the show, i think they should just improve on how izzie's character gonna show off to the viewers beside that denny thingy, get over it.

Yeah I think she's going crazy. I love her character too. I'm sad she's insane this season. I heard somewhere that she's not going to be on the next season.. Don't know though. I'm really disappointed with Grey's Anatomy now since Dr. Burke and Addison are gone. It's so different. But I am very upset with Izzy seeing and sleeping with a ghost!

She's indeed becoming crazy. But I think the producer just want denny return to the show. And that just make izzy more crazy than ever. My guess, for the next episodes, there will be scene of her reing the psychologiest, having therary session like what happen to meredith. And soon denny will be gone. Hiks... thats to bad coz I like him. And probably, if the viewers still want to have more denny on the series, the producer will make another character with the face that just looks like denny. And izzy probably will fall for that man too. Hmmm... Well than the story will goes on again with her being with alex confusing about the love of her life, etc.

LOL i thnk she's goin insane

I have NO idea what is going on with her. I also think she needs help as well. I think she REALLY thinks he is there - but then she knows enough to cover him up with her friends. This is just going in a really weird direction.

yes izzy has gone crazy. I really liked her until this whole little thing with Denny. It's one thing to dream it a couple times but thats enough.
