well that's rather confusing especially for me 
If indeed Heigl isn't leaving the show, per se, but has this bizarre experiences with seeing Denny's ghost and possibly making love to him in the next episode, who might have or will have a brain tumor or mental illness but it's an openning for one of the characters other than Izzie to exit the show, then why wouldn't it be Izzie , the character to exit? Perhaps, the writers are depicting she has some sort of ESP? Or maybe it's another way to end this Denny story?
anyhoo...
i'm luvin this season, thus far!
TIVO , fancast it , I will be watching. BWAAAAHAHAHAHAHA!

I really hope the love scene next week is some sort of dream sequence cos if it's reality something is off... even if we already know something is a bit off about Izzie.
In white, of course.
And so this comment isn't totally pointless, I've got some Ausiello reports. Very interesting! 

The scene with the sleepy little girl was so sweet.
