A familiar face returns to Seattle Grace when George O'Malley's mom, Louise, is admitted. She's in pain but can't stop smiling due to the pride she feels at having Meredith as her doctor. Louise is also all smiles when she sees Callie, who can't bring herself to give out the 411 on her marriage to Arizona.
Meredith wants to do Louise's surgery. Bailey, however, is still plenty peeved at her. She's also dealing with memories of George, who was always just as maddening as Meredith. Nevertheless, Bailey lets Mer do the surgery to help get her mind off the upcoming hearing about Zola. She also gives her some fashion tips on how to impress the judge. Apparently, sweaters make surgeons seem less cold to people. Good to know.
Callie eventually tells Louise everything, and we mean everything, about her life. She worries that all this is too much for her ex-mom-in-law to handle. It's not. Louise is overjoyed to hear that Callie has a baby girl. She can't wait to see pictures!
