“For those of you who have been watching Grey’s for a while, you know that Callie tends to blurt things like “I love you” out – often prematurely. She did it with George, and he never could say it back. She’s a gal who jumps in head first, sometimes blindly, and we’ve seen it bite her in the ass.
So what I love love love is the moment when, after the horrible day that Arizona’s had, after the disastrous party, after losing one of her favorite patients – Arizona comes home, takes one look at Callie in her lingerie and that silly party hat – and Arizona says “I love you” first.”
