In Denver, Lawrence and five others captured Thomas, Jorge, Brenda and Minho to sell them to WICKED as part of a ploy to take down the organization. WICKED intended to use the Immunes to start the Trials again according to Teresa, who was also captured along with Aris and some other girls from Group B.
Thomas, Jorge, Brenda and Minho were able to steal weapons from their kidnappers and interrogated them. Their kidnappers revealed that they worked for the Right Arm, which worked against WICKED, but claimed not to know much of the Right Arm's plans. After some threatening from Minho, Lawrence said that they could take a few of them with him to the Right Arm's headquarters, where their questions about the Right Arm's plans could be answered.
Thomas and Brenda ended up going with Lawrence to the Right Arm's headquarters in a van which Lawrence drove, running into some Cranks who were trying to break into the van. Luckily, they were able to get away.
When they reached the headquarters, Thomas and Brenda were able to speak to Gally, a former Glader, and the Right Arm's leader, Vince. Thomas volunteered to plant a device in WICKED's headquarters that would shut down all firearms in the building.
Gally chose Lawrence to drive Thomas and a pilot to an abandoned hangar where the Right Arm kept their Bergs, from where they would fly to an area near WICKED's headquarters. On the drive over to the hangar, they ran into a large group of Cranks in the middle of the highway. Thomas recognized his friend Newt among them and demanded that Lawrence let him out of the van. Lawrence said that Newt was already too far gone, and when Thomas ran over to Newt and the latter showed aggression, Lawrence threatened to shoot him.
After Thomas is dropped off near the WICKED headquarters, Lawrence is not mentioned again.
