"Ok, here we are." Sorkin said. "The desalination plant is here." Sorkin pointed at the blueprint.

"We're not that far." Gerry said.

Meanwhile, Yoder heard a familiar clacking sound in the distance.

"No, we follow this route here." Sorkin said. "We follow any water mains at junctions in the direction of convergence. Even still, there's barely any turns. Look, just memorize this route."

Yoder headed down a darkened corridor.

A familiar clicking sound echoed in the darkness.

Jess noticed Yoder standing at the entrance to the corridor. Gerry and the other turned.

"What is it?" Gerry asked.

Yoder lit a road torch. A large pack of Troodons faced him.
