While George is looking for articles, he notices a drawer named "Resident's Files." Nice misused apostrophe, there. Inside he finds... Richard's unfinished novel! Well, actually he finds the residents' files. George gazes on them and then slams shut the drawer and runs out before he can succumb to temptation.
Aaaand we're back to the yelling. It's not worth it to specifically go through each argument, but basically the concrete is contracting, crushing his limbs. There's some issue with his liver. The concrete has caused third degree burns where it's touching his skin. And on top of all of this, once they get the concrete off of him and his circulation comes back, the toxins that have built in his blood will rush to his heart and could kill him. Cristina throws in a possible solution but Hahn just snaps at her to let them work. George then runs in and starts to speak, but they all begin arguing over him until Richard again shuts them up and fills us all in on the timeline. The teens didn't call 911 until Andrew had been in the concrete for an hour, and it then took three hours for him to be cut out. So they're left with 4-6 hours max to get him out and into surgery. He orders them to work as a team so he doesn't die. George asks where he should be and the Chief sends him off to work with Meredith for the day since there are already too many cooks in the kitchen.
Meredith approaches Rose who, upon seeing her maybe-not-really-kinda rival, knocks an entire file to the floor. She stammers that Meredith is intimidating because of the Legend of Derek and Meredith. In explaining the Legend (which Mere pooh-poohs), she lets it slip that Derek is selling the land, and even moronic, naïve Rose knows it's because of Meredith even though Derek won't admit it. She tells Mere that she really likes Derek and Mere intimidates her, but Meredith smiles genuinely at her and assures her there's no legend.
The scenes with Alex and Ava back at the house are so hard to watch, I'm not sure I can do them justice. Alex keeps prattling away, trying to engage Ava in the movie, pretending that the woman next to him isn't a shell of a human staring into space. He can't ignore when Ava starts to cry, however, and then in a tiny voice she apologizes and admits she thinks she wet herself. Alex seems taken aback for a second, but assures her that it's okay. As he kisses her on the forehead, she tells him she promises to try and do better. I know we've set up Alex to be the poor, guarded, wronged kid from the horrible, alcoholic, broken home, but even that doesn't excuse the fact that he's basically willfully ignoring how badly she needs professional help.
