Cristina is walking Hunt to each pig's beside, animatedly updating him on all of their conditions. In a decidedly un-Cristina moment, she even calls them champs, and calls Wilbur a fighter. Hunt looks amused, but then genuinely congratulates her on a job well done. She's beaming, and he tells her to write everything up... and put them out. It takes a moment for Cristina to register what she just heard and asks him again. He clarifies that she is to terminate them, and in response she just walks out.
He finds her leaning against a railing, and as he approaches she announces that she's not killing them. She spent the day trying to keep them alive, so Hunt can go ahead and kill them himself. Hunt replies by listing all of the crazy procedures she was able to complete that day, both to point out what she learned but mostly to point out that each of the animals would have months of horrible, painful recovery, and that keeping them alive isn't humane. He turns to walk away and finally she calls after him, "Seriously, you don't remember my name?" He walks back and tells her that he does, but that was before. After a moment, he calmly recounts that in Iraq, he and his surgical team were treating the wounded, doing damage control, and then getting out of the area quick. One day, though, there was an ambush. All 19 of his men died, and he was discharged. "I'm not there anymore, in the before. I knew your name in the before. And now I'm living in the after." He leaves, and she heaves a big sigh.
Callie shuffles into Erica's office, and without looking up Erica just tells her, "If you want to apologize to someone, apologize to Bailey. Thanks to you I made her life a living hell today." Callie replies by announces point-blank that she slept with Sloane. Erica is clearly taken aback but Callie cuts her off to try and defend her actions by reminding Erica of her reaction that morning. Callie says that while Erica saw leaves, Callie hasn't and she may never, or she may see entire forests. I just love primetime gay sex euphemisms. But Callie assures Erica that regardless of what she figures out, she wants to be with Erica right now, and that involves telling her the truth -- which happens to be that she slept with Mark. Twice. Erica is clearly working to absorb everything and just answers, "Okay."
