Downstairs, Lexie is listening with rapt attention as Aaron tells them that Alex was the oldest brother, then Aaron, and that they have a younger sister named Amber who is about to graduate from high school. He says she's wondering why she should bother going to college and he doesn't know what to say because Alex is the smart brother while he is just a mover, so he shouldn't be the one giving advice. Alex comes in then and they hug, but Alex asks fairly pointedly what he's doing there. Aaron claims he was driving to Portland and therefore in the neighborhood, and when Alex points out that Portland is 300 miles away Lexie jumps in and points out that his brother is allowed to come say hi. Mere sends Lexie off to work as Aaron reminds Alex he hasn't been home in seven years, and when Derek expresses surprise Mere sends him away too. She then introduces herself to Aaron, who assures Alex that his little sister was ten the last time he was home. Alex asks him again what's going on, and finally Aaron comes out with it, and admits that he thought since Alex was a doctor, he could take a look at something. He pulls up his shirt to reveal what looks like a golf ball embedded under his belly button, and asks the doctors if he should be worried about it before we fade to white.
At the hospital, Callie and Mark meet up at the coffee cart and when Callie asks him about his most recent date with Teddy, she is thrilled to realize they finally Did It. Arizona then bounds up with a grin, but she and Callie clearly don't know what to say to each other and finally Arizona grabs a slice of poundcake and goes on about just how much she loves it. When she leaves, Mark asks Callie if "poundcake" is code for something dirty -- because if not, that conversation was awkward and pathetic. Callie admits that because she and Arizona aren't talking about the baby issue, they wind up having idiotic conversations like that one about poundcake. Mark asks just how long they are going to avoid the subject, but Callie replies by changing the subject to Teddy, and even though he calls her on it, he's clearly thrilled to talk about how amazing the sex was. He tells Callie, "I blew her mind."
