I agree with you on both counts.

At least there are theories for those.

Izzie is either dying of brain tumour or she's finally insane and she'll be committed. Either one is fine by me. The last one, she could be dragged away to the nuthouse in a straitjacket, and we won't have to see or think about her ever again. She can eat bugs and rip her hair out for all I care, as long as she's off-screen.

As for the rant #2, my friend theorized last night that Sadie is just the ABC suits and writers' way of covering their ass after firing Brooke Smith right after the controversial lesbian sex episode. I bet after last night, they'll drop the lesbian storyline. If not, maybe a few more episodes.

Aw, I love Izzie. When she isn't driving me nuts, anyway, heh. I'm hoping for an operable brain tumor or at least something that won't leave Alex gutted again. Oh, Alex.

Bet your friend's right. I wouldn't doubt they were all "quick, gay the show up!" :|
