We've read the Grey's Anatomy spoilers, heard about the kisses and talked about the show's promising return at length. All that's left now is a two-hour season finale, one that promises to have us glued to our seats - then jumping out of them!

Everything reaches its breaking point tonight. Meredith and Derek near the end of their clinical trial - and battle their own personal trials - while Izzie confronts Alex about Rebecca and the strange Mark / Callie / Erica tension continues to boil.

What do you think will happen on tonight's Grey's Anatomy finale?

Please let us know. Discuss "Freedom" with fellow Grey's Anatomy fans before, during and after the show in Grey's Anatomy Insider's forum...

After the show, we'll have our official Grey's Anatomy episode recap up after the show, along with our photo gallery, music guide, quotes and Round Table discussion!
