I'd like to start off by saying that cliff hangers are the devil!
But they do make for interesting discussion!
I doubt it's Burke....that'd be too obvious and I recently saw an interview w/ Katherine Heigle aka Izzie where she said noone at that time had been fired....these episodes were definitely shot before that.http://www.youtube.com/watch?v=HpWgGML3XOQ
I'm calling Meredith being technically dead when she's pulled out of the water (I'm sure by McDreamy due to part 1's obvious bathtub foreshadowing and the "knight in shining whatever" comment). I expect she'll be revived by our stunning crew of medical miracle workers and possibly spend the third episode of the arc in an oxygen tent or the like while the doctors (and we at home) hold our breaths waiting for her to regain consciousness or lucidity.
This is just my opinion. I really can't see them killing off Meredith for good. Or anyone for that matter. As far as I know, the cast has all signed 5 yr contracts (with the possible exception of Eric Dane aka Mark Sloan....I'm not sure about him) and unless somebody is fired, I'm thinking the next to die would be Ellis Grey....but Mer has already had a recent mother of a incident (pun intended) w/ Ellis, so I doubt it'd be soon.
As far as Isaiah Washington is concerned, if he had been fired, I really think it would have been confirmed by multiple parties by now. Let's face it, these people have NOT been able to keep any of the other developments in the whole Washington saga under wraps. If he was gone, somebody at ABC would have confirmed it.
If anyone is interested, here is a link to a GA site who has a death watch running:http://www.greysanatomyinsider.com/2...the-field.html
P.S. did I mention I'm like obsessed with this show?
