They walk into an on-call room, Cristina looking stern yet nauseated. But since this is her look a lot of the time Owen doesn't realizing that it's serious and starts talking about ordering some food. In reply, Cristina announces that she is pregnant. It's actually quite a big step for her to have told him immediately what was going on, but that's as far as her maturity and giving goes. He's clearly happy but also tries to calm her; when he tries to touch her belly, though, she smacks his hand away and yells at him that there is no way she is doing this. They start to argue, and she doesn't want to hear anything he has to say. Eventually, though, he reminds her that they are partners and asks if they can just think about this together. Dejected, she nods. He assures her that he loves her and wouldn't want to make her miserable and run away to Meredith, but this is all just a lead-up to his suggesting that this might not actually be the worst situation in the world. Cristina can't deal and just whines and yells like an angry teenager fighting with her mom. She point-blank tells him that she doesn't want a baby and he responds by pointing out that she already has one. She's aghast at this and accuses him of "going lifey" on her, and then tries to start a debate about when life actually begins. Her facade crumbles, though, and appears to feel pretty betrayed by his actually wanting her to think about having this child. She maintains that she doesn't hate kids and thinks that they deserve to have parents who want them. Owen pleads that he does want the kid and that one day she might too, but she's certain that is lunacy. Finally, though, after a lot of gentle pleading on his part, he convinces her to agree to just think about it with him before doing anything.
Cristina, of course, then goes running away to Meredith. She sees that Mere is in a conference room with Richard and Derek and peeks through the window. Mere sees her and gives an infinitesimal head shake which Richard doesn't notice on account of all of his yelling. He still wants answers that Mere is still not giving up, and he warns her that once they get all of the info from Alex they'll figure out the dates on which this happened and what patients were involved. Seriously, Richard? No tiny pang of uncertainty that you might realize what possibly happened? Meredith again maintains that nothing she did changes the trial, SIGH. That line has gotten very old, very fast. But the worst thing about this situation is that it's brought Self-Righteous Derek back with a vengeance. He yells at Meredith that she doesn't get to choose which patients get what and when Meredith tries to say that the trial is still blind since he doesn't know who got what, Derek haughtily spits that the trial is over. He then decides to get personal and yells that she screwed him and the hospital. As Derek rants, Alex knocks on the door and hands his report to Richard, who looks it over and then pulls out his own datebook and starts to flip through. Quietly, he finally says something but Derek can't hear over the sound of his own voice, which is growling at Mere that he did this whole trial for her, to cure her disease. I'd say this whole "treating the spouse like a colleague" has failed rather spectacularly at this point. Richard speaks up and tells Derek that Meredith's shenanigans were for Adele. Meredith remains silent; Derek is gobsmacked.
