Oookay....by a show of hands who thinks Meredith will come up with a brilliant way to save Archer? *raises hand*

Bridget, I agree. As soon as I saw her face, I thought that. I think she's gonna suggest something about the clinical trial. Knowing Meredith she'll say it in front of Addison and Archer and Derek won't be too pleased!
But the Bailey/Sam scene made me laugh. As did the end of the Lexie/Mark one with Lexie suddenly shouting. I like them as a couple, Lexie's innocence mixed with Marks ways, just makes me smile.
