"What?" Meredith balks at the idea of carrying one of those things, but there's no time for hesitation, and with a grim look, she heads over to grab it. The urge to check the agent's pulse as she takes his gun is difficult to resist; getting them out of here, doing this kind of thing, might be Sean's job, but hers is to help the sick and the injured, not to take their weapons and leave them lying there. They would have done the same to them, she reminds herself. They just don't have the time. It doesn't help much, but she edges back toward the door anyway, glancing over at Sean for his lead, her hold on the AK-47 cautious and awkward. She's never carried a gun before, let alone one like this, and any appeal or interest that might have held in other, more peaceful circumstances is outweighed by this being a matter of practice, not theory. It's loaded and she doesn't know what she's doing, fingers far from the trigger.
