I hope schizophrenia is NOT IT. No mental illness, please. Even though I am not a fan of Alex and Izzie together, I do LOVE Alex and Izzie having a mental illness would be way too BRUTAL on Alex!!!!
I have to say that I think the most viable theory here is that Izzie is sick in some way and that Denny is the "angel of death" and is leading her toward the light. I would hate for Katie to leave (HATE IT-- Izzie is one of my most favorite characters), but I can't think of any other viable theory. AND Shonda was quoted as saying that Izzie definitely doesn't have a brain tumor but NOT that Izzie doesn't have ANY type of neurological disease or trauma. She was very specific there, which leaves disease (or possibly accident) still open as a possibility. Denny is bringing her into the light. His letting her go to bed with Alex last epi is simply him knowing that she's not ready to go... quite yet. I hope she doesn't go. I hope her illness is discovered in time for treatment to work and then (even though it will break my heart) she'll have to say good bye to Denny to continue living.Oh, and GEORGE WILL NEED TO BE BY HER SIDE -- HE'S HER BEST FRIEND!!!! George will convince her to stay. That's my wish of how this plays out!!!
