Back in Iraq, he and Dan are riding along while the driver tries unsuccessfully to contact anyone. Hunt's gaping-ab-wound patient asks where they are going and Dan and Hunt tell him they're going to the Green Zone, and then he'll go to a hospital in Germany and then home. Hunt then asks Dan if Teddy made it there already -- as if Dan would know more than he does, they are squashed into the same vehicle together -- and Dan just laughs and says he's sure Hunt's girl is fine. Hunt unconvincingly says that they are just friends, Dan tells him to keep telling himself that, and then... they explode.
In the aftermath, Hunt kicks his way out and sees what appears to possibly be an arm on the ground, though I can't be sure and quite honestly didn't feel like dwelling on it. Let's just say shit's bad and go from there. The patients and driver are all dead, but Dan is still alive and yelling to Hunt, trying to figure out what's what. Hunt goes around the toppled vehicle and finds Dan pinned underneath.
Cristina has to call his name a few times to break him out of his trance, and when he asks her what she reminds him that he was the one who paged. Her voice is clearly worried -- this kind of behavior isn't totally foreign and she knows it can be bad. There's no time for possible PTSD issues, though -- he immediately starts interrogating her about if she performed a particular test on Kim when she was admitted the week before. Cristina realizes that he stole Kim's chart but he ignores her and plows ahead, demanding that she answer the question while adding that the test could give a false positive, and then Kim would be killing herself without all of the correct information. Cristina points out that the test in question is routine so she probably did it, and he jumps all over her, demanding to know if "probably" is good enough for her and Teddy -- he's also clearly needled by how unruffled she is and how she seems more worried about him than Kim. She asks him what's going on, but he just storms out with the chart.
Callie is still with the Idiot Brigade, and Nick tells Tommy to call his wife but to downplay his injuries as a simple broken leg. Mark is tending to Phil's frostbitten fingers and when he dunks them in water, Phil starts to holler and says it's worse than when he broke his ankle climbing Kilimanjaro. Apparently Tommy made it to the top while the other two got altitude sickness a half-mile from the summit. Callie laughs that they are hardcore, while I say they are ridiculous wannabes -- don't you get tired of doing this stuff if you wind up with protruding bones each time? But Nick sells insurance, and Phil and Tommy are accountants, and Nick thinks they have to do these things to keep their "blood moving." Then there's a really contrived moment where they tell Tommy to show a picture of him with a rubber chicken (?) on the peak of Kili, but Tommy accidentally shows a picture of his daughter, dressed as a ladybug for Halloween. Conveniently, Mark is able to take that and show it to Callie, asking her to say she doesn't want one of those for herself.
