He knows it's a nightmare, but right now, he's trapped in it. He's been in places like this before, and it never gets any easier. He is looking all around, hearing the sounds of the fight, but there are no bullets coming at him for the moment. Booth cannot rest though. He is still on alert, all of his sniper's senses ready for action. He is seared by this experience, physically and mentally. He just wants a way out now. But one is not forthcoming.
