Hey you're right! According to the ABC website the final IS tonight. I read somewhere it is on the 22nd. But tonight is MUCH better.
I'll have to wait for after the weekend since I have theatre tickets for tomorrow evening and I go there straight from work. So my Grey's final will be Saturday or so.
If anyone sees it sooner than I do, please post a spoiler if she lives or dies.
But seeing the clips online I think we may not even find out. It oculd end with her having that surgery and then showing her unconscious with ominous medical background noise or Denny or whatever.
