ER. John "Bachelor #0" Carter treats Jennifer, Eli's ex-girlfriend from Once and Again; she's clutching her stomach. He asks how long she's had the pain, and she says it's been a few hours. He asks how long it's been since her last period, and she says it's been seven weeks, and that she did a home pregnancy test two weeks ago; it was positive. Carter asks whether she's seen her gynecologist. The camera pans to the next bed, where Chen is treating a man with a migraine. She asks whether he's on any medication; he names a couple of drugs but says they aren't helping and that his headache keeps getting worse; the pain is all around his right eye. As Carter gloves up, Jennifer tells him that this is her first pregnancy, and asks whether she's having a miscarriage. He distractedly tells her that he won't know until they do some tests, and a pelvic exam. He pulls the curtain and we pan back to Chen and Migraine Man; he's saying the pain pounds with every heartbeat: "I think it's the numbers." Chen doesn't get it and asks, "You're an accountant or something?" He explains, "Binary numbers -- ones and zeros, electronic data." Finch gives me a migraine too, dude. I can relate. Migraine Man starts droning, "Eighty, one-forty-six, seventy-two, one-oh-nine. Eighty, one-forty-six, seventy-two, one-oh-nine." Carter pulls back the curtain. Chen's like, huh? Carter points to the numbers on Jennifer's monitor as Migraine Man reels them off: "Eighty, one-forty-six, seventy-two, one-oh-nine. Eighty, one-forty-six, seventy-two, one-oh-nine." "Freaky!" says Chen appreciatively. Suddenly there's a crash, and Dr. Dave rushes into the room, closely followed by Yosh. Off-screen we can hear a woman's voice shrieking, "I warned you! Pervert!" Dr. Dave's patient maced him. Wah.
