Lexille is stuffing medical supplies into her bag, about to bolt, when Jackson catches her and does the worst Ricky Ricardo impression in all of history. He implores her that if she doesn't have this pacemaker put in, she'll die. He offers to explain the procedure to her but she recites all of the details from the brochure and explains while he gapes that she has a photographic memory. He thinks this is an awesome reason for her to go to med school, and she laughs in his face. He presses her, insisting that this could be her glorious second chance -- to become a doctor, meet her sister, and gain a new family, and all that starts with fixing her heart. Instead of mocking him she starts to cry and leans in to him, and he really awkwardly tries to hug her with the least amount of actual physical contact possible.
Cristina is eating her banana when she walks by the surgical board and sees that her surgery is now assigned to both Yang and Webber; infuriated, she storms away.
She storms right into Alex's office, already yelling at him as she opens the door, demanding to know why Mere is now assisting. Her voice trails off, though, when she sees Alex and April engaged in some heavy making out and groping. She just chuckles to herself and saunters out as they watch her in horror.
Alex runs after her as he pulls on his shirt, begging her not to tell anyone. He's forgotten his glasses and without those but with the desperation in his voice, this is the Alex we know. Cristina just wants to use it to get her surgery back, and she doesn't flinch when Alex tries to threaten that he'll make sure she never gets time in an OR again. She knows she holds all the cards, and she orders Alex to take Mere off of her surgery. Alex tells her that it was Callie's decision, so she turns and goes to find her instead.
As the Shepherds work on the baby, Addison tells Derek she wants him to meet with someone from a preschool. Derek gets pissed, but it's not because of the ludicrous notion of having to get your baby into school before they are born (oh yes, I am fully aware that this is totally a real thing, by the way, as I've had friends go through it -- I just find it nuts that this is the world we live in) but because he's Derek, and he's an ass, and he doesn't want to do anything family-related much less talk about it in front of colleagues. She blows up at him that they have to talk now because he's never home, spending every night in his trailer on the land where she's convinced he's never really going to build a house. So, it's just as uncomfortable to be a scrub nurse in Elttaes as it is in Seattle, having to witness ugly personal clashes while you work. When something goes wrong with the baby they yell at each other some more, and Addie finally tells him to focus on his part of the surgery and she'll take care of hers.
