Ausiello was also kind enough to remind us of comments Shonda made back over the summer about Izzie's storyline for this season:
"Izzie's got a love story, and it's a big one," she told TV Guide back in August, "one that I've been kicking around in my head for a bit, one that required me to take a huge leap of faith in myself, one that is so secret that I have not told anyone. Not the writers, not anyone."
Oh course she didn't tell anyone, because they would say she was BAT SHIT CRAZY. There's a difference between a leap of faith and jumping over the edge, and she's obviously chosen the latter. I can't believe that Denny is going to be in another three episodes. I'm disgusted with this show. I really hope Izzie has a brain tumor, because a medical answer to this psychoticness is the only thing that could possibly make this storyline palatable. Either that or Izzie getting hit by a bus. Ughhhhhhhhhhhh.
