Mark is talking to Derek and tries to assure him that Meredith will come around on another baby, but Derek isn't so sure. Dudes, when a beloved pet dies most people don't try to replace it right away; this is the loss of an actual BABY and only happened about four hours earlier. Let's all give Meredith a moment, shall we? While we're doing that, let's talk about how weird it is that Derek is immediately hoping for another baby. I don't think he's actually supposed to come off as callous, though when you give it any tiny bit of thought, it does. But hey, we've already established that I can't figure out anything about Derek's thoughts and feelings this season, so we'll leave that and see how it works out. Mark thoughtfully offers to work Derek and Meredith into their parenting schedule for Sofia, but Derek isn't so interested. Man, does this scene feel forced, as if someone at ABC was like, "Seriously, guys, this episode needs at least one comedic scene. Give me ONE, at least." There's usually a much more natural balance between humor and drama but this week the humor all seems unnaturally shoved in. Avery runs by with a phone in his hand and Mark asks him about the boy; Avery tells him that the kid's nose is basically hanging off, among other awful things, and he'll call when Arizona is ready for them.
The phone Avery has is for Arizona so that she can talk to Alex. He tells her everything that's wrong with the baby, including pneumonia, and she tries to suggest different things they can do to get the air flowing into her lungs again. They don't have the right device but Alex is able to figure out something else that might help, and tells Arizona that they'll call her once they are back in the ambulance. Before she hangs up, she reminds him that they don't have a lot of time.
Teddy and April are digging around in Laura's chest and find a huge tear in her ventricle, forcing them to put her on bypass. Someone comes in with Henry on the phone and she apologizes profusely for not being able to see him before he goes in for surgery. He tells her it's fine and points out that after the way she acted last time, it might be for the best that she's not there. The two of them get all gushy as they joke about driving each other to the airport, etc. and finally Teddy tells him she loves him and they hang up the phone so that she can attend to Laura and all of her copious bleeding.
Lexie is in Henry's room getting things ready for surgery and he decides to admit his embarrassing med school dream to see what she thinks about it. She's a little bit surprised but not appalled or anything, and just assures him that as an older student he'll have some good perspective that the young 'uns are lacking. He finally tells her that Teddy doesn't like the idea and tells him to give her some time, because it's true that being a med student is pretty hard on a relationship. Henry is hopeful, though, because Lexie's got such a good thing going with Jackson. Reluctantly, Lexie admits that they aren't together any more. Henry tries again, suggesting she's with Mark, but Lexie admits a little bit wistfully that she's not with him either. Henry lets this sink in and then decides to change the subject, asking who is operating on him. Her voice gets all funny as she lies that she doesn't know, but he's in too much pain to notice anything funny.
