After a shocking season finale on Greys Anatomy leaving us all in limbo on whether or not Dr. Izzy would survive, we now have an answer. Katherine Heigl will return for the next season of Greys, at this point it is not known how much of the season she will be a part of but at least she is back. On a sad note T.R. Knight (Dr George O'Malley) will not be returning this season. If we keep losing people from the original cast I just don't think it could posibly be near as good of a story as it used to be... But I guess we'll just have to see.
