Derek and Grey the Younger are in with their patient, Lori -- a cute, friendly, twenty-something who is telling the hilarious story about how she passed out at her first post-law-school interview and wound up with her skirt around her waist. The reason she passed out is because she's got a cyst in her brain, and they are going to open her up and drain it, easy-peasy. Obviously, something is likely to go horribly wrong because this show isn't known for sweet patients whose surgeries go swimmingly. She asks about a tumor that they found and Derek explains that it's small and benign, so they want to leave it alone for now. He adds that if it ever starts to cause problems they can take it out -- it's so easy, Lexie could do it! -- but they're going to just handle the cyst today. When the docs walk back out into the hall they meet up with Mere, and Lexie seems kind of freaked out that she's going to be joining them though I'm not entirely sure why. Derek says with a smile that Mere is thinking of coming back to neuro but Mere shoots that idea right down.
It turns out that preemie Tommy needs heart surgery, so Teddy, Arizona, and Alex are sitting with Morgan to explain everything. She wants to wait until the brain bleed is resolved but Teddy tells her they need to operate now. Callie comes in to tell Morgan she can treat Tommy's hip dysplasia except really, she's just there to conveniently witness events and serve as a lurve mentor for Alex. She brings Arizona a scone but when Arizona incredibly wrongly turns up her nose because it's pumpkin -- the best baked good flavor in all the world in the history of time -- Alex takes it and tosses it to Morgan, telling her she has to eat. All of the ladies (minus Morgan) notice the gesture and raise an eyebrow; Morgan turns it down because of nerves. They all start to leave to get Tommy ready and Morgan teases Alex that he loves all this since it will look good on his Boards. Alex admits that's true but insists he just wants to be there, but this prompts Morgan to tell the women not to let him in since he was up all night. Cue the raising of the other eyebrows. Once the youngsters leave Callie asks if Alex should really be hooking up with his intern. Arizona is apparently blind and dumb because she's appalled at the idea and insists nothing is going on and Alex is just trying to be a more caring human being. Callie doesn't buy that for a second and insists to Teddy, "They're doing it."
