And here it is, folks: the final appearance of the Vomit Comet this season. Here, it's wired to Bill Macy as he horks up chunks of The Budget Gourmet's mashed potatoes and Salisbury steak. They plop into an emesis basin that Abby's holding under his chin. Based on how it looks and sounds, I will say only this: it will be a while before I can eat hummus again. Chen walks up to treat him, and we see that her right eye is bruised and blackened. Abby notices and stares pointedly at Chen so that Chen knows she knows -- yikes, what a sentence -- and Chen blinks self-consciously and continues with her workup. She tells Bill Macy that he's jaundiced, and that his fever and vomiting are probably symptoms of his end-stage cancer. She's not sure what they can do to help, really. "I'm not ready," he cranks. "We can treat you for the pain..." she begins. "I said I'm not ready!" he insists. Abby rattles off under her breath the list of tests she'd run and things she'd prescribe, and Chen, affirming Abby's instincts, says, "Thought you were a nurse today." Chuny loyally says, "Abby's a nurse every day. That's why she's going to kick ass as a doc." Yeah, yeah, yeah.

Outside the room, Chen asks Abby how she scored on her boards. Abby admits that she hasn't heard, and Chen marvels that it's a bit close to the wire now. Abby pauses and leans against a table. "Dr. Chen, is everything okay?" she asks. Chen deliberately ignores the implication and gives her an answer about Bill Macy. As she blithely walks away from Abby, we see Abby looking skeptical and concerned.

Pratt's on Chen duty next, flagging her down and immediately noticing her shiner. "What happened there?" he asks, sternly. She shrugs that it's nothing. "Doesn't look like nothing," he scolds. Chen offers up what sounds like a sincere attempt to allay his concerns, claiming that since her father's not sleeping, she isn't either, and she forgot to turn on a light and ran into a doorframe. Then she slips away before he can contest that ridiculous story. I can't believe she didn't come up with a better cover story than "I ran into a doorframe," since that phrase is pretty much on the poster for abuse. And her tone and facial expressions certainly don't indicate that she was hoping he'd read between the lines.
