Meredith's getting tired of being asked that. All she really wants is to go home now, her and Sean both, and have all this be over, or, barring that, just to put down her weapon and hold onto him instead. Neither's happening now and she won't let herself hide behind him like she wants to. She can't hold her own here, but that doesn't mean she's going to turn meek either. "I'm Meredith," she says, though it's just her name, not a real answer. She looks over at Sean, hoping for some guidance as to what she's supposed to do in a situation that's far more his territory than hers, unsure if the truth might be a liability and unable to come up with a lie. "Doctor Meredith Grey. And I'm his girlfriend. I'm sorry to get in the way; it wasn't my plan either." That much, at least, she means completely. She'd really rather not interfere with whatever it is they're doing, but she doesn't seem to have much of a choice.
