Cristina, Meredith, and Ellis's ashes are having coffee in the cafeteria. Cristina suggests scattering the ashes off the roof, but Meredith tells her that her mom was afraid of heights. Cristina tries to tell her that they're ashes and therefore can't have phobias, but Mere maintains that she has to put her mother to rest and not become her. "I need to not die emotionally crippled and alone. And I need to not attend the wedding of Derek Shepherd and Sydney Heron. I need to put my mother to rest." I feel a little like Ellis actually would like just coming to work at the hospital with Meredith every day, but I guess that's too creepy and unsanitary to be a permanent solution. Their musing is interrupted when George and Izzie sit down, and Cristina sighs heavily and turns away from them. After an awkward silence, Izzie says they can just ask. Meredith asks if they're together, and when they say yes, she clarifies, "In love together. Sexy love, not sibling love." Izzie says yes, but their chemistry says no, no, no. It's actually uncomfortable to watch and try to believe that they're a romantic couple. She marvels that they've been doing it this whole time with no one noticing. Hey, I marvel at the same thing. Izzie says that they only did the deed once, and adds that now they're waiting, "Out of respect." George, trying to act like he's comfortable with this conversation, pipes up to add, "For Callie's feelings." Cristina snorts at this selfless declaration and leaves the table. Meredith claims she's not judging, but Izzie and the rest of them know better. As she gets up to leave herself, Meredith tells them sincerely that she's happy for them. It's not entirely convincing, but it's sweet that she's making an effort.
What did I tell you? Alex and Ava are naked in bed, clearly post-coital, when Alex gets a page. Seeing that it's Norm, he ignores it and instead asks Ava how she's been. She answers that she's in love with her daughter and gets all gooey talking about how she sucks on her fingers. He then asks about her husband. Carefully she answers, "My husband's in love with my daughter too." She then comments that Alex is tired, and he admits he hasn't been sleeping a lot. She says that she hasn't either because of the baby, but that she learned a trick of wrapping her in whatever shirt Ava was wearing that day. Alex smiles as he notes that then she can smell her mom. After a moment, Ava asks him what they're going to do, but Alex is finally asleep and she just smiles as she watches him. I enjoy that the bunk bed seems to now be a double instead of a twin, making illicit booty that much easier and more comfortable.
Now here's a face we haven't seen in a little while -- Dr. Hahn has come to the hospital to help harvest Erin's organs. She asks where the heart is going, and Richard explains that he hopes it will be to someone in the hospital who has not yet agreed. Cockily, Hahn comments that she's never had a problem convincing someone to take a heart, and Richard has to explain that the heart in question would be coming from the prospective recipient's daughter. At that moment Cristina and Norm turn the corner, pushing James's bed. Cristina sees Hahn and asks a waiting Izzie what she's doing there. When she hears about the transplant, Cristina makes a beeline to Hahn while Izzie tries to fight her off, claiming that Erin is her patient. Cristina just goes up and smoothly introduces herself and offers her help in surgery. Izzie then jumps in to introduce herself and explain that this is her patient and she has any pertinent info. She's much less smooth than Cristina, sounding defensive and, frankly, juvenile, but Hahn just comments to Richard that he has some eager junior residents. With an eye-roll that says he'd rather he didn't, he tells her to take her pick. When it's just the ladies, Hahn turns back to Cristina and answers, "Well, Yang, I appreciate the offer, but I date men. So I don't think you'll be able to impress me the way you've been able to impress your mentors in the past." Cristina can only stutter in response, so Hahn explains, "My theory is, if you had the chops in the OR you wouldn't need to try and impress in the bedroom." She then commands Izzie to follow her, and off they go, Self-Righteous and Self-Righteouser.
