Paging Dr. Shepherd! Paging Dr. Shepherd! No, not that Dr. Shepherd. We're talking about someone completely different. Let's just call her McSister. Yes, Addison's former sister-in-law is a promising young neurosurgeon who just happens to be part of a team that's been asked to help Kayla, the surrogate coma patient carrying three babies.
Amelia Shepherd (guest star Caterina Scorsone) is a force to be reckoned with as she spars with her boss, the brilliant Dr. Geraldine Ginsberg. When Dr. Ginsberg says she can't help the patient, Amelia offers an option of hope. This ticks off Dr. Ginsberg, who promptly fires Amelia from her team. Kayla's husband, Eddie, asks Amelia if she would be willing to do the surgery. She agrees to try to save his wife.
Both Addison and Vanessa are against the surgery. It's just too risky. But Charlotte signs off on it and Sam will be in the OR to maintain the cardiovascular function. Amelia gets angry when Addison brings the prospective parents of the three babies by to guilt her out of operating. She accuses Addison of settling in her personal life and now with her patients, too. This actually leaves Addison a little rattled.
As Amelia operates on Kayla's brain, a blood clot puts all three babies in distress. Sam has to repair the clot, but the babies won't survive the procedure. Addison has to get them out them now. The third baby is not breathing. Vanessa offers to help, but Addison tosses her out of the OR. She performs CPR on the infant and, after a few tense moments, the baby takes a breath. Whew!
After Sam repairs the clot, it's up to Amelia to finish the surgery. But she's having a bout of self-doubt. Sam gives her a little tough love speech to help her get back on track. He wants them to work together to show her brother that he's not the only Shepherd who can make magic. Just like that, Amelia is back in the game.
Things look bleak as Kayla is not responsive after surgery. At least, she's not responsive at first. Eddie believes that his wife is in pain. He wants to know if that's good or bad. When Amelia checks her, she realizes that Kayla is not having a pain response. No, this type of response means that she's waking up!
As a doctor, Addison lectures Amelia about getting lucky after such a risky procedure. As a former sister-in-law, she says that she reunited a wife and mother with her family and that's something to celebrate. Sam tries to bask in the big win with Vanessa, who wonders why he didn't stand up for her in the OR. He asks if he's in love with Addison. When Sam can't respond, Vanessa has her answer.
When Sheldon bails on a sex education seminar at a retirement center, Charlotte asks Cooper to pinch hit. After a painfully awkward lecture, an elderly man named Oscar asks for help. He's been having some pain during intimacy. Unfortunately, that's because he has prostate cancer. Oscar wants to continue his intimate relations with his lady friend, Nora. Radiation therapy would hinder that. He opts not to have any treatment.
Charlotte asks Cooper to talk to Oscar. He does. As it turns out, Oscar worries about being less of a man. Cooper tells a tale of how he pushed away the woman he loved because he was feeling emasculated. He admits that he was wrong. This seems to hit home with Oscar, who agrees to have the radiation treatment. Charlotte is grateful. Cooper apologizes for being a jerk, but he's still not ready to have a drink with her.
Fife admits to Pete that he slept with Naomi and told her about William's illness. Cooper is also spilling details about his issues with Charlotte. Pete comes home wondering when he became the man that other men tell their problems to. Addison doesn't have an answer, but she does have another problem to toss his way. It's about that time he thought she was Violet while in a feverish state. That time he said, "I love you."
Pete tells Addison he will always love Violet, as she's the mother of his child. That doesn't mean he doesn't love her. He's moved on. He's happy. That makes Addison happy. Lucas looks happy, too. Yes, they're one big happy family. DING DONG! Someone's at the door. It's Violet. Initially, it looks like she's there to see Pete. But when she sees Addison, Violet puts two and two together. Her demeanor changes instantly as she says, "I want to see Lucas." This could be trouble.
