Frank has his shirt off again. Yay! He's hooked up to a machine, from which he determines that he's still in "normal sinus rhythm." He asks Chen how much longer he has to stay in bed, and Chen says he'll have to wait until she gets his electrolytes back. He asks what his patients are supposed to do, and she says she called his unit and told them he was taking a sick day, so they called in a replacement for him. He grins and says, "Well, then, I guess I'm your prisoner." Chen gives him a look like, "You're damn right. Now, where did I leave those handcuffs?" Lisa, standing behind her, asks whether Chen has seen Mark, who was supposed to help her with Kim's paracentesis. Chen says he's in trauma, but that she can help her. Lisa introduces Chen to Kim, and then runs through what she's already done to prepare. Chen says it's fine. Lisa asks what tests she should order, and Frank answers instead. Chen smirks and thanks him. Lisa says, "There's your fluid," and they watch as it drains into a jar. Chen says it looks like Lisa has "good flow," and leaves, telling Lisa to call her if she needs anything. Lisa turns to Kim and says, "That wasn't so bad." Kim, who's started wriggling in pain, says, "Actually, it's starting to hurt." Lisa offers to re-adjust Kim's catheter, but when she touches it, Kim yelps, "Hey!" Frank, leaning out of his bed, says, "Uh oh. If I were you I'd order an upright chest film, stat." Lisa looks alarmed.
In a trauma room, Mark has lost Estrella's pulse. They start compressions. Chuny asks what the problem is, and Mark says it could be septic shock, or meningitis. He's in the process of shocking Estrella with little wee paddles when Carter appears at the door. He offers to come back later, but because Mark is passive-aggressive, he does not take Carter up on the offer, but rather, asks him, testily, what he wants. Carter says that Adam is doing better, but that he could still use (in Carter's opinion) more dialysis. Mark tells him to give Adam another half-hour of dialysis. Mark, pay more attention to the teeny baby you're shocking!
Frank is sitting at the desk, working on a computer, wearing his gown. Dr. Dave, eating something out of a bedpan (possibly shit, given the grin we've all seen him sport from time to time), tells Frank that patients aren't allowed behind the desk, but Randi tells Dr. Dave that since Frank is a nurse, she gave him permission. Dr. Dave reluctantly relents. Chen finds Frank there and fondly chastises him for being out of bed. Frank says that some of his labs were back. Dr. Dave tells Chen that her "patient has low sodium." Frank attributes that result to four litres of water he drank after his workout. Chen hustles Frank back to bed until the rest of his tests are back; he comments, over his shoulder, "I think she wants to keep me here." Dude, who wouldn't? Dr. Dave continues picking at his meal and says, "That guy's a piece of work, huh?" Randi replies, "And you're not?" Dr. Dave asks what that's supposed to mean, and she points out the fact that he's eating Cap'n Crunch for dinner, out of what she calls "an emesis basin." Carol tears into the doorway and asks Randi whether her nanny called again. Randi says she didn't, which frees Carol up to observe what Dr. Dave is eating, and from what he's eating it. Dr. Dave explains that there was nothing in the lounge but a box of cereal and (wait for it) "a jar of milk." Realization floods over Carol's face and she snarls, "A jar of milk?" He says, "What?" and she snorts, "Oh, God, Malucci!" Note for the slow: Dr. Dave has been eating Cap'n Crunch moistened with her breast milk. Hey, if the glands that produce lactation are as big as Carol's heart, she should have no problem coming up with more.
