Meredith (about Louise): Oh, she knows you're married.
Callie: What? How? H-How did she find--
Meredith: She saw your ring this morning. She asked me and all that I said was that you were happy.
Callie: It's not your place to say anything.
Meredith: She's going into surgery and she's scared, and she's alone and she misses you. I know it's complicated, but I don't think it would be a bad thing if you were there to hold her hand when she woke up.
