Alex finds Callie to ask if she needs any help that day, on account of Stark hating him and choosing to work with another resident. She and Mark had been walking together but he's left out of the Arizona-bashing that ensues: Alex thinks maybe heartlessness is a peds thing while they both say they pity the kids in Africa since she's making them fall in love with her now, but then she'll probably find something better and take off. Mark has just been watching them, too smart to jump in to their dangerous vortex of hurt feelings, and they finally walk off as Lexie comes up. Mark finally says hi to her and then, at a loss, blurts out that he misses her. She tries to stop him but he can't seem to stop himself and he asks if she's seeing anyone. She is absolutely not amused and turns to leave, but as she walks away he pathetically calls after her again that he misses her.
Because things weren't already awkward enough between them, it seems that Mere is working with Owen for the day. They wait in the ambulance bay for their patients to arrive and after a moment of awkward silence Owen asks her if she ever goes fishing with Derek. She informs him that she doesn't because she's a surgical resident with no time, and even on her days off she's at the hospital, just like Cristina should be. That said, she launches a bit of an attack on Owen, asking him what his plan is for Cristina in the coming days -- cooking class or bowling with Bailey? They're saved by the arrival of two ambulances but Owen calls out that while he's not sure, bowling with Bailey sounds fun. He's not wrong, but he's also choosing to completely ignore her point. Their conversation is cut off by their patients -- first up is Trina, who lacerated her ear after falling 100 feet into a ravine. Unfortunately, her husband was what broke her fall, and he's in the other ambulance with much more than just an ear injury.
Meredith takes Trina, who seems to be okay but who is also understandably panicked about her husband. The two are on their honeymoon, and were hiking and decided to take a picture but when they gave someone their camera, posed, and kissed, the ground collapsed and they fell into the ravine. She begs Mere to tell her that Jason, her husband, isn't going to die, but of course Mere can't say and looks a bit tortured about it.
She goes to check on Jason, who is in awful shape. His abdomen is so distended that he looks like he's got a bun in the oven, but which actually means he's got massive internal bleeding. His vitals start to drop so they sprint him to the OR, and Trina watches them go by, crying.
