Just got to watch this episode. I agree with everything you have said above !! I have to admit that I also want to see an end to the mer/der saga. They need to evolve this relationship a bit more. Then they can have the normal couple issues if they need story line ideas, but not this will I or won't I dance by mer !!!
Lexie + Sloane I like, Lexie + George I do not like !!! I think that because Lexie is a really nice person underneath it all, she could bring out Mark's good side a bit more. I think how this will play out though is that Lexie will pursue George, but he will rebuff her. All the while Mark will be becoming more of a friend and will be there to pick up the pieces. That's how I'd write it anyway !!!!
