In Trauma Green, Arrowbelly asks when they're going to take the arrow out. Carter says they'll do it up in the operating room. Shane reports that Dubenko is on his way. Shane can't find a vein for an IV, and neither can Abby. Sam asks if anyone checked his feet, and ties off an ankle. Carter tells Abby to set up for a central line, and Abby passes it off to Darlene, who says that Jake said she was cool about letting students do procedures. She adds, "Actually, that's how he sold me on the switch." Abby hasn't heard anything about a switch. Arrowbelly asks if anyone called his mom, and Sam promises that they're working on it. Darlene explains that Jake switched shifts with her so that he can finish his rotation by working nights with Neela supervising. Carter tells Arrowbelly that they're going to intubate, and Shane promises that, when he wakes up, he'll be recuperating sans arrow. Sam gets a vein in the foot. Darlene keeps explaining that Jake said he wanted to get a sense of how other interns work. Carter notes that Arrowbelly's blood pressure is dropping, and tells Abby to go next door and get the rapid infuser.
