In the outdoor OR, Hahn is looking at the ultrasound while Richard explains that they're going to start, but since Ray's upside down, the blood isn't pooled at the bottom of his heart. Hahn jumps in to say that they should still use the somethingorother instead of the thisandthat. Richard leans in to make sure Meredith heard, and after she confirms it, she asks Ray how he's doing. Outside, Hahn leans in to say be careful because she could nick an artery. Izzie then guesses that she could cause a rupture, and Hahn rogers that and lists a number of other things that could go horribly wrong. "Basically there's about six different ways she could kill him." While most TV shows pretend that standing two feet away from someone, or standing around a corner, means they can't hear what someone else is saying, this time we're actually seeing something realistic. Ray pulls off his oxygen mask to ask, terrified, if they're talking about him. Meredith tells him not to listen and then turns around and orders, "Dr. Hahn, shut up." Hahn looks shocked but then yells inside, full of false cheer, that Ray's going to be fine. She then turns and quietly tells Izzie to get an 18-gauge needle, "before this man's heart explodes in his chest."

Alex is finishing up the last of the surgery, and Callie asks how he's doing. His nose itches, which she says is the anxiety since he knows he can't scratch it. But it turns out his anxiety was warranted, as some blood then squirts out of Jacob's chest onto Alex. I like to think that, while filming this episode, the special effects team was running around having the equivalent of a water fight with all their squirty-blood contraptions, because they clearly have a lot of them on hand. Callie and Alex go into crisis mode; she asks what he did, but he claims nothing. Upstairs, Ava jumps up at the commotion and Alex looks up at her yet again. Man, no wonder this guy's chest exploded -- it probably was craving Alex's attention after all the time he spent staring after his lovah instead of at the incision.

Lexie asks for yet more gauze, and Nick understandably seems pretty worried about the amount that he's bleeding. She assures him that they're also putting blood back in, but he wonders if it's at the same rate; he's feeling queasy and weak. He asks nervously if he should call his family, but just then, she realizes that the bleeding has stopped. Mark sweeps in and asks Nick if he's okay, and Nick asks if he looks okay. It's a pretty great moment, since his entire left side is solidly coated in blood. Sloane confirms that the bleeding has stopped, but Cristina's very technical-sounding reason why also includes the caveat that it could start again. Mark assures them it won't, he'll fix it, and in unison Lexie and Nick inform him that there's no OR. But as he did a few moments ago when he left his surgery, he assures them that there will be, and orders the girls to bring him down. Nick turns to Lexie and declares, "I'm in love with you now. I've forgotten entirely about my ex." She puts a bandage on his neck and smiles, shaking her head. And though I'd love to say she's being ridiculous, he's actually quite charming and cute and I don't blame her for the smile.
