Will Izzie be returning to Grey’s Anatomy?

There’s been lots of rumors speculating that Katherine Heigl along with Sandra Oh, T.R Knight and other Grey’s Anatomy favorites may be making a return for the series 300th episode… but as we know, once you mess with Shonda Rhimes… you’re out! However sources have said that Thursday night’s episode will feature characters that pay tribute and remind us of the original cast and is sure to be filled with nostalgia! Which character (dead or alive) do you wish Shonda Rhimes would bring back?
