I know we've heard about this before, but it seems to be coming back out about Katherine Heigl leaving the show. I may not really care for her character, but I think she seems like a down to earth person.
I'm not sure if it's positive fact that T.R. is leaving, but I think he deserves something that'll give him more time and more of a spotlight and something where his talent will show. I think he deserves more than what he's been getting on Grey's, all ten seconds an episode. ;(
Hopefully they'll move onto bigger and better projects. :D
