'Director' of an agency we don't know exists in a place we don't know exists? Garcia wanted to retort, but at Derek's touch she held her tongue. For the moment. She would rather have given it free rein; this whole situation had her thoroughly freaked out, and while making smart remarks wouldn't necessarily have changed anything, it at least would have given her some sense of being in control of something.
And 'new quarters'. She didn't like the sound of that either. "New quarters?" she repeated, an edge in her voice. "So you're telling us that not only do you have no idea how we got here, you're expecting us to stay?" Vance was projecting the air of a man who was on their side (if being sort of an authoritative jerk about it) but she still saw no reason to take anything he said as canon. Maybe he'd brought them here himself. Maybe he was trying to manipulate them for some nefarious purpose.
Maybe she was getting carried away, but then again, supposedly they'd been sucked into an alternate universe and maybe 'carried away' didn't really have any meaning anymore.
