When they got to the small town that Jack had been trying to find those years ago when he'd met Nate, Jack was in a funk. He didn't really feel like walking all of the way out there. Not only that, but he'd forgotten to figure the travel time correctly, and it was late afternoon. They'd either have to spend the night in town and walk out tomorrow, or walk in the dark.
As Jack was afraid that if he waited one more night he might lose his resolve, he decided that he'd go ahead and drive the RV out there. It was only going to be this once, and Jack would go back and cover the tracks afterward. They ought to be able to make it out there by nightfall if they drove, and then they could get it over tonight.
Jack told Sammy to e-mail Nate that they were coming as he drove out of sight of the town on the road. They then pulled off the road and headed out into the desert.
Everything went well, until they got to the sand dunes. Jack had been nursing the RV along the whole time, over the rocks, through the creek beds, revving the engine the few times they almost got stuck. When they came to the dunes, Jack didn't really think about it, he just downshifted and headed up the first one. By the third dune, Jack started to regret that he'd decided to try driving on the sand. The RV was fishtailling and losing traction. Jack was having to work it up each dune slowly and was trying to keep from losing control each time they came over the top and slid down the other side. Sammy had come up to sit in the passenger seat, coiled up and laughing at Jack's driving.
As they came over the top of the fourth dune, the biggest one yet, Jack saw that this was the final dune - the stone, the lever, and somewhere Nate, waited below. Jack put on the brakes, but he'd gone a little too far. The RV started slipping down the other side.
Jack tried turning the wheel, but he didn't have enough traction. He pumped the brakes - no response. They started sliding down the hill, faster and faster.
Jack felt a shock go through him as he suddenly realized that they were heading for the lever. He looked down - the RV was directly on course for it. If Jack didn't do something, the RV would hit it. He was about to end humanity.
Jack steered more frantically, trying to get traction. It still wasn't working. The dune was too steep, and the sand too loose. In a split second, Jack realized that his only chance would be once he hit the stone around the lever - he should have traction on the stone for just a second before he hit the lever - he wouldn't have time to stop, but he should be able to steer away.
Jack took a better grip on the steering wheel and tried to turn the RV a little bit - every little bit would help. He'd have to time his turn just right.
The RV got to the bottom of the dune, sliding at an amazing speed in the sand. Just before they reached the stone Jack looked across it to check that they were still heading for the lever. They were. But Jack noticed something else that he hadn't seen from the top of the dune. Nate wasn't wrapped around the lever. He was off to the side of the lever, but still on the stone, waiting for them. The problem was, he was waiting on the same side of the lever that Jack had picked to steer towards to avoid the lever. The RV was already starting to drift that way a little in its mad rush across the sand and there was no way that Jack was going to be able to go around the lever to the other side.
Jack had an instant of realization. He was either going to have to hit the lever, or run over Nate. He glanced over at Sammy and saw that Sammy realized the same thing.
Jack took a firmer grip on the steering wheel as the RV ran up on the stone. Shouting to Sammy as he pulled the steering wheel, "BETTER NATE THAN LEVER," he ran over the snake.
THE END
