April and Matthew are doing pre-marriage counseling and the Reverend walks in with the results of their compatibility test. It's obvious from her chattering that April is nervous and yet ultra-competitive -- when he tells them they aced it she lets out a whoop and she and Matthew high-five. He then leaves to get them exercises for the coming week and once he is gone Matthew nervously tells April there is one problem that they haven't discussed -- while they are compatible, they aren't totally equal. April is surprised, thinking it didn't bother him but Matthew says that it really does. She declares that they should fix it, and he seems happy but a little bit surprised. Simultaneously, they both say the simple solution to this problem: She says they should get a joint checking account while he declares that they should have sex. I guess that wasn't one of the questions on the test, then.
Cristina has Smash give her the rundown on all of her patients, and he's so on it that he even realizes when she's trying to trick him up. As a reward for being his sharky self and keeping her patients alive all night, she gives him a coffee. He asks her if she's going to go to Mere's printer presentation but she quickly comes up with an excuse and says she'll see him afterward.
Bailey and Princess are talking to their Patient o'the Week, whose esophagus they are going to remove and replace with a piece of his colon. Despite Princess pointing out that they are using a part of his large intestine, not his ass, he and his partner can't help but come up with a lot of good puns since he is a well-known Seattle restaurant critic. He says that he can now honestly say that something tastes like crap. Basically, they are completely awesome and Bailey and Princess are obviously both fond of him. Bailey tells them that barring any complications, he'll soon be bossing them all around about where to eat. She seems to lose her confidence just infinitesimally, but no one seems to notice.
Once she and Princess are out in the hall, however, she orders the resident to give the guy another enema. Princess is surprised since he's already have one, but this sets Bailey off and she spits that they are dealing with the most contaminated part of the body, so he needs another. She asks if she can do it after Mere's presentation and Bailey claims she doesn't care as long as it's done before his surgery. She definitely seems to be on edge.
Emma is at the hospital and we learn from what Arizona is telling her that a spot opened up in maternal fetal medicine and Arizona thought of her for the job. She recommended her to the Board and the step is for an interview, which will be with Callie. Arizona admits that Callie is her ex but for the most part reassures Emma that it should be fine. Callie, meanwhile, is talking to Owen and thinks that this is going to be a great chance to grill the girl he's dating. Owen is kind of distressed at the idea and assures her that there is no need, but he doesn't seem to convince her of that before they all meet up and Emma and Callie are introduced. Owen looks somewhat worried as the two walk off.
Smash finds Cristina and excitedly tells her that in Japan, doctors are making conduits seeded with a patient's own cells so that their bodies won't reject them. He thinks that they could do this for baby Nathan, but Cristina is skeptical. However, he has an answer for each of her protests: he has printed out all of the Japan studies for her to review, and scheduled all of the various tests they need to find out if Nathan is a candidate. Cristina is still doubtful and tells him they'd also have to file for a compassionate release from the FDA, since this is experimental. Smash tells her he'll begin that process and asks her to just consider it. When she looks through a window at the heartbroken parents, she finally agrees.
April sees Matthew in the ambulance bay and runs out to talk to him. He's all excited -- does he think they're about to have sex up against his rig right then? April tells him that she wants their first time to be amazing and to feel right, and that she'd prefer if they had committed to each other in front of God before having sex. He'd still like to do it now, and has her pushed up against his rig while he kisses her knowing that this will maybe start to change her mind a little. He tells her he is going to love her for the rest of his life and he's sure God knows that, and she's horny and kind of torn and finally agrees to it. He's the happiest little boy in the world.
As Bailey and Princess are working, Bailey continues to be super hard on her about every move she's making, warning her that if she's not careful she'll cut the guy's bowel and cause spillage, and you don't ever want those two words in the same sentence. Princess is fine, but Bailey finally takes the job from her and starts working herself. She's so busy feeling for something, sure she's doing a better job, that she doesn't hear Princess yelling at her at first: "Spillage!" The camera angle and light go all funny again as Bailey retreats into her own head but she finally snaps back to reality and they get to cleaning up the mess. She seems anything but okay, however.
They get the guy's insides washed out and patched up, but Bailey makes them continue to rinse many more times and she insists that they have to close him up immediately. Ben, in his best Soothing Voice, coaches Bailey to take it one step at a time and reassures her that this was a routine complication and that they got everything under control. He asks her if she's okay, and she stands, pulling on one finger nervously for a while before getting back to work.
