When she gets out of the elevator, Mark grabs Callie to ask her if she knows how to put a crib together. She's shocked at the question but he explains that Sloan is coming home, so he bought a crib, and it wobbles. Callie affectionately points out that he's become a "sweet nerdy dad." Mark then sees a blonde from behind who he doesn't recognize, and he becomes single dad on the prowl and excuses himself. He walks up and delivers a pick-up line, then jumps and screams when a newly-blonde Lexie turns around. She tells him that she made a change but then stops, realizing that he didn't recognize her and was therefore hitting on her. Mark tries to deny it and then tries to tell Lexie that she isn't a blonde, because blondes are either badass or fun, and that she's a brunette. Hey! On behalf of all badass, fun, and generally awesome brunettes out there I take issue with that. She's wearing a whole lot more eye makeup than usual but is actually pulling off the blonde way better than I would have thought after seeing a still picture of her about a week ago. Avery gives her a low, "Damn," after witnessing the exchange but she just snaps at him to shut up.
She walks up to Alex who starts and then stares at her, and she gripes at him to stop because she's probably changing it back. Alex is supportive in his own Alex way and says he understands that she got dumped and then went for the extreme makeover, that girls always do it. She corrects that she wasn't dumped, that she wanted to do something for herself on Valentine's Day, and he asks how that's different than what he just said. He leaves, and she declares to no one in particular that she's changing it back.
Mark and Hunt arrive at the ER right behind paramedics wheeling in a number of patients on stretchers, and Callie greets them to run down the list of things such as sucking chest wounds that await. April calls after them and Derek is surprised that she's still there, but she chirps determinedly that if he's there, she's there. She tells him that a rep from OSHA is waiting in the lobby and that the TV crews outside want a statement. Callie cuts back in to talk about the medical side of things, so April tries to talk over her and the two wind up shouting for Derek's attention before he quiets them and pointedly asks Callie who to see first. She sends him to a trauma room while April tries to get him to see the OSHA rep, but he goes in to deal with the patient while April looks on dejectedly.
