Donna had expected the look. If she hadn't been so used to space and time travel or been greeted first by Jack and then all the rest, she'd have done the same thing to the first person who spoke to her. "Then you get someone to bring you to a computer. We've got a board up for anyone in our situation. There might be people you know here. Some are lucky and loads are." Others not so much, but there was no reason to be a downer. She wondered if she should keep going or not. Maybe just a little taste of the Apocalypse spiel wouldn't hurt?
"And after you've done that there's the pesky bit about this being a war that you're in, but I figure you'd want to know if anyone else you know is around first. They're usually better at explaining things than a stranger you barely met." Donna thought it was a fairly good plan. Maybe it'd work?
