Malik brings in a vagrant named Mr. Bartlett, found under the El, who promptly tells a passing Mark to kiss his ass. Ah, a vagrant after my own heart. Mr. Bartlett's gurney slams into one containing a rule-out CVA, Chen's patient. Chen is accompanied by Frank; Mark asks about his work-up, which Frank assures him was fine, and Chen explains that Frank saw the ER was "getting slammed," and offered to help. Mark goes on his merry way, and Lisa jogs up to him and anxiously tells him that there was a complication with her colon cancer patient. Mark says that Benton told him, and reminds her that he had planned to help her. Lisa says that, because he was busy, she asked Chen instead. Mark says that Lisa didn't give Chen Kim's complete history, because if she had, they would have tapped the mid-line, and the bowel would never have been, as he puts it, "perfed." Lisa sighs, and says that Kim has spiked a fever, and she thinks he's septic. Mark tells her to make sure Kim is comfortable now. Lisa tells him she wants to stay with Kim, because he has no family, and Mark tells her that she can't, since she's needed to attend to patients (like, duh), and that after her shift, she should go down to pathology to practice procedures. Lisa pouts off, and Dr. Dave calls Mark over to see "a live one"; apparently the patient was feeding his friend's gila monster when it bit him and clamped on to his hand. Dr. Dave asks if they'll have to kill the animal, and Mark replies, "Only as a last resort." Blah blah blah reptilecakes, they use clamps to get the gila monster off, and Dr. Dave catches it in a bucket. Point? I don't know either. It was a pretty lizard, though.

Elizabeth is still taking heroic measures to keep the potential donor alive. When Mark comes in, she gives him non-Robert's vitals, and he tells her that the heart won't last much longer (he's already crashing), and that the patient is a DNR. She refuses to call it. He reminds her that they're too busy for her to be wasting her time on a lost cause, to say nothing of tying up a trauma room and a passel of nurses. Yeah, really -- I'm no longer on your side, Ginger. Elizabeth refuses some more, insisting that non-Robert's parents "would want some good to come out of this tragedy." No sooner has she delivered the line than they recover normal sinus rhythm. Lily asks Elizabeth if she wants a lidocaine drip, and she declines, saying she'll do it, and, looking at Mark, tells Lily to "go help the other nurses." Mark yells, rather angrily, "Don't keep flogging him! I mean it! He's a DNR!" She says nothing. He leaves. Way to be authoritative, Mark. Except for the -- well, you see where I'm going, here.
