Lisa: What can I say? I crossed over to the dark side.
Sars: A Star Wars reference. Now you're cool, ER.

Pounding credits. I'm only at the credits?

In a trauma room, Lisa is telling Luka that Todd's facial films are clear, and that she's paged an oral surgeon. In a flat, affectless voice, Carol asks, "Luka, do you want me to update his tetanus?" Lisa says that Todd had a shot a year ago, and Luka says, "Guess not," and introduces himself to Lisa, who reciprocates in kind. Carol studiously avoids Lisa's eyes, because she's a jealous baby. Haleh watchfully takes in the whole scene, plainly expecting a catfight. Carol asks Luka if Todd needs more meds. Luka turns to Lisa to ask her, and Lisa says, "Sure." Carol almost, but doesn't quite, roll her eyes. Luka smiles, "Nice job," and books. Lisa leans across the patient to murmur, "Well, we never had doctors like that up in OB." "Easy on the eyes, isn't he?" Haleh agrees. Lisa asks if he's single, and in the same Nurses of the Corn voice, Carol tells her that Luka doesn't talk about his personal life. Lisa coos, "Ooh, tall, dark, handsome, and mysterious." She then starts gathering up what appear to be syringe wrappers and the like on Todd's bed. Carol, alarmed, asks what Lisa's doing. Lisa cheerfully says that she's cleaning up, and Carol goes through her tone library to find one that merges professionalism with barely-concealed resentment, and uses it to tell Lisa that she's "got it." Lisa says, "Don't be silly," and Carol insists, in her drone-y voice, that she'll do it. Just as cheerfully as before, Lisa stops, and goes to leave, pausing at the door to tell Carol, "I'd love to see some pictures of your girls later." Non-committally, Carol says, "Sure." Carol, if you want to be a doctor, just go to medical school already, and quit taking it out on the female med students who, unlike you, actually had to stones to go through with it.
