Meredith and Derek have been "sharing the truth" in the supply closet, and are pulling their clothes back on, giggling, in the afterglow of all that honesty. Seriously, what happens if someone actually needs supplies? I've yet to see a supply room used for its actual purpose around here. When she tells him to leave the room first and she'll follow, Derek deduces that they're having not just breakup sex, but secret breakup sex. That, or they're trying not to advertise that they're spending their work hours studying each other's anatomy. He guesses that it's a secret because of Cristina, and Mere sort of waffles around about it and says, "If she knew..." Derek finishes that then she'd have to talk about herself and Derek, which would take so much time that there'd be none left for Cristina's problems. Mere points out, "I told you we don't talk about it."
Alex is ordering his interns around for the day, and gives Laura (the one I thought was a nurse last week) scut two days in a row for some slight backtalk. He then yells at them to get lost, all of which to show what a badass resident he is -- a self-proclaimed Nazi. The Chief then heads over to him with Dr. Norman Shales. Yay, Edward Herrmann! Richard explains that he transferred there from the greatest hospital at the best university in the history of the world, UCLA. Alex is happy to meet him and assumes he's the new OB/GYN. Unfortunately, he is very, very wrong. Norm is his new intern, and at Alex's horrified look, he declares, "Don't worry, son. This tugboat's ready to pull his own weight." Richard cheers him on, asking heartily, "Age is just a number, right, Norman?" Alex mutters to himself, "A pretty important one." I think Alex is just intimated because Norman appears to be literally twice his size. In fact, by comparison, all of Seattle Grace seems to be populated by munchkins now.
