Last night, the mercurial and controversial fifth season of Grey's Anatomy came to a dramatic, hanging-off-a-cliff conclusion. Cristina loves Owen, Lexie and Mark have commitment issues, Bailey has a broken heart and Meredith and Derek are married. Sort of. We think.

Perhaps most significantly, and incredibly, we still don't know if Izzie Stevens (Katherine Heigl) lives or dies. Oh, and the same thing now goes for George O'Malley (T.R. Knight).

Say what now?

Follow the links to read our recap of the two-hour finale, which was technically listed as separate episodes (they link to each other, so you can transition back and forth easily):

• "Here's to the Future"
• "Now or Never"
