I am excited to see Alex's storyline progress and find out what makes him tick. We've met family members from almost all of the main character's except for Alex.
Honestly, I am glad to see Katherine Heigl go. I think all her negativity about the show has been horrible and weighs the rest of the cast down. I don't think she is a great actress because she plays the same character in every movie. I think she will regret leaving TV and come crawling back much like David Caruso did. It is obvious that Grey's can continue to be a great show without Izzie Stevens. The addition of Owen and the Mercy Wester has given the show a shot of adrenalin, Izzie who?
