"Ehm," he says, trying to field TJ's question in the best way he can. "Well, technically we just monitor the Rift. It does a lot of spitting things out, from other places, other times." He glances at the pair of them warily. Technically, the rest of this is classified, even by Torchwood standards, but he doesn't really see the harm in sharing, considering. "And it sucks things up and sends them away." Sometimes it takes people. He's nearly said as much to John before, but he's not certain the other man's really understood what it meant before.

"Like I said, we can't really control it. We can't really even predict it. We just sort of..." He shrugs. "Deal with the fallout, I suppose." He glances aside at the pair of them. "The only time we tried to do anything specifically it sort of. Fractured time itself, a little. Which we fixed," he corrects quickly, "but I'm not sure it's really meant to be. Used. Not in the way that your gates are, anyway."
