Here's a little Grey's Anatomy spoiler tidbit from E! Online's Q&A today. Okay, so we already knew this thanks to previous comments from Chandra Wilson, but here goes anyway:
Q: Waiting with bated breath for the Grey's Anatomy finale. Spill!
A: As Chandra Wilson said, "In [the finale], we do ultimately find out what [happens with] George (T.R. Knight) - he does make a big decision in that episode. Izzie has a lot of medical [issues] in that episode. And then we have our normal ER catastrophe that goes on. It has to be something bad going on where all the doctors have to assemble. That much I know."
