Okay so for Sloane. He and Addison were serious and were supposed to have a baby, but she aborted it. Then when they tried to make it work, she slept with Alex, like it was said above. I felt really bad for Mark after that. And yes, he does sleep around too much, but I think this was a HUGE slap in the face for him, and I felt so bad for him. I also feel bad for Rose tho, because Sloane basically told her to have sex with Derek, because she was just being afraid that he would lose interest. When we find out Derek is still hooked on Mer and isn't going to keep going with Rose, or so it seems.
And Callie and Hahn. There was that awkward pause at the end. But I think it has to do with Hahns feelings toward Callie, and Callie not reciprocating them. We will just have to see what happens with this relationship.
And Christina, very weird. I do not think we have ever seen that part of her. I was just watching the last episode of Season 2 where she tells the Chief she lost her drive, her ability to tell on people, to get herself forward and back in the OR. And Webber wouldn't tell her what to do to get that back, because he didn't want to be to blame for her being less of a person. I think this is another example of her being human, and seeing that part of her. But Burke should have mentioned her, I would like to see him come back for a few episodes too.
Meredith and Derek. I really don't know how to feel about them. Because I have been anti-them for awhile, because ti was too dragged out. But now I would like to see them together and to see Meredith happy again. I wish they could have saved the soldier, and I am excited for them to have to champagne. My husband quoted that line yesterday "We will open this champagne someday" haha
