Derek's in the middle of brain surgery (no big) as Lexie tries to make Amelia's case for a simulation run. Derek thinks his sister is too emotionally wrapped up in the case to see clearly that she can't help this woman, though Lexie argues maybe Amelia's passion is going to make her try harder. Derek sighs that the bottom line is that the procedure can't be done in 90 seconds, but if Lexie needs to see it for herself, so be it. Lexie's all, "Yeah, maybe YOU'LL be the one seeing something!" but then thinks better of trash-talking the surgeon who's wrist-deep in gray matter.
Turns out Alex is doing the gastroscopy on the boy himself because he needs Morgan/Megan to continue to quiz him for the boards. He could not look more disinterested in his intern as he demands more and more questions. He might want to glance her way, actually, because she's looking clammy and disoriented, which might be the resting state for surgical interns, but on a television show, we all know it means "imminent peril." He calls her "Megan" again and asks for symptoms on the latest index card, but the symptoms she rattles off -- tightness in the chest, indigestion, blurred vision, shortness of breath -- aren't on the cards, nor is the fact that this "patient" is 24-weeks pregnant. Alex keeps his eyes on the gastroscopy and berates her a little more for asking weird questions until she ultimately collapses. He yells at his fellow doctors to help her as we go into commercial. Oh, hell, is this another episode where Alex is a terrible person and then later we're all supposed to feel sorry for him because he hates himself? How do I ALWAYS get these episodes?
After the break, Megan's conscious again, in a hospital bed being examined by qualified doctors and also Alex, who yells at her for not telling him she was pregnant. She's like, "Everybody knows I'm pregnant; the Pregnant Intern is kind of notorious." The OB/GYN on hand says she's not having contractions and the baby is fine, but Alex surmises from Morgan's symptoms that she's having a heart attack.
Counseling. Owen is browbeating Cristina to come up with a reason she doesn't want kids, but -- for the billionth time -- Cristina tells him she's not damaged or abused, she's never been mugged by a baby. She just doesn't want kids. Owen says, verbatim, "NO ONE doesn't want kids!" Oh my God, I hate this so much already. Look, there are two ways to unpack that statement: Shonda and the writers either believe what Owen is saying -- that there's some biological imperative to want children and even when people think they don't, they eventually do -- or else they think "everybody wants kids" is a self-evidently ridiculous statement, in which case they're loading down a previously likeable character with the biggest pile of BS belief I've heard from someone on this show, and that includes the time the blonde thought she was having sex with the ghost of her dead boyfriend.
