Burke is more responsible. Christina is his subordinate, not the other way around. Burke is the one with the shaky hand, not Christina. Chistina is the girlfriend, over-achiever, accomplise. Yeah, she is a surgery junkie, but Burke can say no. He is her boss. He is the Surgeon and she is a resident! And after Burke crushed, totally crushed Baily he can leave the hosipital as far as I am concerned.
I loved the interactions of Mark and Addy with Shepards sister. What did he call her, Nancypants? LOL The show has been so dark with all the McStomping around that has been going on, it was nice to see these characters in a lighter light.
Just when you really want to hate Alex, he does something awesome and is all melty all over again. Sometimes I think he is my favorite character on the show.
