"I need the parameters of the terminus point, especially if there aren't any parameters for the origin points of potential victims." Tosh tapped one finger against the case of her laptop a moment. "I don't even know for certain how many dimensions I need the program to work in. At least six, to start, possibly more."
Jack watched as Tosh worked, keeping one eye on the street. He wasn't going to leave her alone with the Doctor at the moment - this wasn't the Doctor he was familiar with, and he had come with Tosh in order to make sure she got home safely. He didn't want to explain to her family if something happened, and he'd left her alone.
