"I know we're not talking about the ghosts," Rodney says, exasperated. "But these people are backwards enough that--oh, nevermind. At least we know that its got a little dial thing." There might be a hint of sarcasm in his tone, but it's fine. It's fine. Peering at the Life-signs detector, he purses his lips. "Okay, there are more than a handful of...somethings here. We'll have to narrow it down."

He looks between John and Ianto, and then because honestly Ianto is right, he makes a shooing gesture. "Go on. Walk. The scan for Natha metals is short range." He only has the comparison for metals because examples are scattered all over Nadril--which means probably a lot of false positives from that, too, unfortunately. Unless he can get a bead on the Natha's specific energy signature for their small power sources... Well, he can try and narrow the band while they walk and see if he gets any hits. "Fend off the scavengers."
