With rumors circling that Sandra Oh may be returning to Grey's Anatomy when it returns in September, we decided to put together a little recap of why Cristina Yang is the best thing to have ever happened to the show (not that you needed reminding). If the rumors are true, then we cannot wait to see what kind of havoc she will wreak on the cast. Will she break up Owen and Amelia? Will she become chief? Will she give Meredith the kick in the ass she so desperately needs? We can only hope. So, until September, join us as we remember why Cristina Yang was a gift from the heavens.
