This finale was very dark. Grey's has a tendency to be bipolar in the tone department; one episode light and funny, the next dark and twisty. I wish it would make up it's mind!! The Izzie and Alex scenes are the definition of why this episode rocked! Justin and Katy bring such intensity to their scenes, and this episode was no different. When Alex screamed and pleaded with Izzie to get the surgery, you could see how heartfelt it was.
Kimberly Elise guest starred in this episode as Izzie's doctor and jeez am I hoping they bring her back next season! She was really great, and totally fits with the cast. The scene with Bailey, Callie, and Izzie's doc was so cute.
