On the trip back to Terra Nova, Quantum tries to explain to Chris in the Muddy that a move to the southern hemisphere would be good for them. "The important thing is, the poison rain never fell there," Quantum says. "You'd be safe. Your children would be safe, you could even spend time on the Overside if you wanted to." Chris in the Muddy tells Quantum that the crew of the Enterprise wouldn't want their tunnels so much if they were truly infected. "We don't!" Mayweather says, spinning around from the navigational controls in frustration. "We only want to help you, make you healthy!" He glances quickly at Quantum, then turns back to his controls. "Was that photograph of Vera Fuller and her daughter shale?" Quantum asks, getting down with their lingo. "Do you really believe we created it to trick you? You're human. So am I. Humans help each other." Muddy Mum doesn't say anything, but her son does: "When we track back to the Underside, we'll return your crewman only if you promise to leave!" Quantum asks if they could just tell their people what he proposed. Chris in the Muddy sticks his nose in the air and looks away, pursing his lips. Damn, he really doesn't want to share any of Terra Nova Spa's beauty secrets, does he? The shuttle pod lands and Quantum makes like he's going to get out, but the pod quakes a bit. "All thrusters are down!" Mayweather tells him. The pod rocks again. "Fire them up again," Quantum commands, as the ground suddenly cracks open and swallows them up. Mayweather transmits to Enterprise that they have a commercial, ur, emergency.
