Abby interrupts the moment, calling Carter's attention to a patient's file. She can't help noticing that a 500-pound gorilla is humping Carter's leg. "What's wrong?" she asks. No one speaks. "Nothing," Carter finally says, snatching the files out of her hand and running off to go walk on water somewhere. Susan lamely attempts to change the subject, but Abby's on to her. Susan exhales guiltily. "Carter assumed I was in the loop," she confesses. Abby doesn't get it. "The drinking loop," Susan clarifies, clearly uncomfortable. Abby stares at her, then averts her eyes, humiliated. "Oh," she says in a small voice. "He's concerned," Susan says, trying to defend Carter's loose lips, but sadly the ship has already sunk. Abby chases Susan through the halls, spewing desperate explanations to the effect that she didn't want Susan to feel uncomfortable around her because of the alcoholism; she just wanted them to have a fun time. Susan insists that it's absolutely not something she will discuss because it isn't her issue, which is totally right. Abby follows her into the ladies' room, because the horse has to be dead before she can beat it into oblivion. "I'm sorry he got you into it," she apologizes. Susan seems like she really wants this conversation to end. "It was an accident," she swears. "Well, it's not like it's a big secret, either," Abby says, killing the poor horse right there on the bathroom floor.

Suddenly, a needle clatters to the floor. After a painful pause, a hand snatches it back up. Abby and Susan swap confused, nosy looks. Inside the stall, we see a terrified-looking Weaver. She finally decides to suck it up and leave with her head high. She exits the stall. "Kerry," Susan says. "Susan," Kerry nods awkwardly. "Abby." Oh, good, they all know each other. Weaver looks incredibly uncomfortable, and we smash-cut into the commercials wondering what Kerry's problem is with needles today.

After the break, Susan and Abby are chewing the fat about the syringe mystery. "You don't think she could be..." Susan trails off. "No chance," Abby stops her. "That's what it looked like!" argues Susan. "Weaver? The straightest gay woman since Janet Reno?" Abby snorts. "I don't think so." Susan sasses that perhaps Kerry was practicing her flu-shot technique. Unwashed Peasant #35 makes an unwelcome return to ask if he can be treated yet. "Later," Susan snaps. "Go back to your seat, Phil." He shuffles away. Chuny calls Abby away to another patient, but before she goes, Abby wants to take a steam-roller to the horse's cadaver, because beaten dead horse looks better when it's squashed into a bloody pulp. "Listen," Abby begins. Susan immediately looks for an instrument with which to slice off her ears and mail one each to Carter and Abby in silent, crimson protest. "It's not something I talk about much," Abby stammers. "We're friends, Abby," Susan reassures her. "If you want to talk, you know where I am, and if not, that's okay too." Abby thanks her without making eye contact, and leaves hastily.
