Even in the midst of a storyline that continues across at least three episodes, this show doesn't lower itself to offering previouslies, so we jump right in: Addison shows up at the hospital, carrying Lucas so we know just how attached she's gotten to him. Charlotte asks why she has "that baby" here, so we know just how cold and heartless Charlotte still is. Then Charlotte fills Addison in on why she paged her: Coma surrogate Kayla's husband, Eddie, is calling in the "big guns," in the form of a doctor named Ginsberg. Addison gives Lucas to a stunned Charlotte so she can get on this case. Charlotte introduces herself to Lucas.
In Kayla's room, Eddie's telling her stories about their kids and then tells Addison that Dr. Ginsberg is going to come and wake Kayla up. Addison doesn't want him to get her hopes up, but he thinks he'll get their miracle and wonders why Addison can't just believe. He says he unplugged the love of his life, and she didn't die, which has to man something. Just then, in walks former SNL cast member Nora Dunn, playing the famous Dr. Ginsberg. She doesn't even know who Addison is, so ... burn! She then snottily asks Eddie to leave, which he's fine with: "Whatever it takes." Dr. Ginsberg is basically cold and brusque and doesn't even pay attention to what Addison has to say. Then she looks behind Addison and says, "Thank you for joining us, Dr. Shepherd." Addison greets a cute girl as Amy, and Dr. Ginsberg is surprised to learn they know each other, until Addison explains she was married to her brother. So, here we have Amy, who wants to be called Amelia now, but with me she'll have to settle for Little Shepherd.
Addison and Little Shepherd catch up in the hallway. She didn't want to spoil the surprise of coming by telling her. Turns out Derek didn't tell Addison that Little Shepherd's a neurosurgeon or that she's a fellow for Dr. Ginsberg. Blah, blah, smalltalk. Then Sam comes in and Amy tells him he's still hot. Charlotte brings Lucas back to Addison, since the nanny didn't show, and Little Shepherd thinks there's a lot of stuff Derek didn't tell, but Addison explains he's her boyfriend's baby, not hers. Ginsberg calls Little Shepherd away, so Amy says they'll talk later, and she's missed them. Sam calls Little Shepherd "Hurricane Amelia," and Addison wonders what kind of family is it where the black sheep ends up being a neurosurgeon. Uh, isn't the black sheep in Addison's own family a neurosurgeon? Sam tells Addison how great she is with Lucas, and he's all sweet. Vanessa walks in in the background, so when Addison and Lucas leave, he walks to her. She's sad, because she thinks Kayla being in a coma is her fault. Sam tries to convince her otherwise, so they kiss. She says it is, but thanks him for saying it isn't
