On their way back, Luke destroyed most of the equipment he had used on the mission and dumped the remains in a river in Big Bend National Park.
Putting on the sportswear which he had come in, he and Selina got into their car in the parking lot and returned to Shackelford.
Entering town, Luke dropped Selina at her place.
Selina asked, "You're not going home?"
Luke shrugged. "I'm planning to spend two days in the mountains near my grandpa's ranch to relax."
Selina understood what he meant.
He had killed so many people in Mexico, and he didn't want his family to notice anything wrong.
Selina thought for a moment, then said, "I'll go with you. I need a quiet place to rest too. Let me tell my mom."
She then got out and entered the house before returning a moment later.
Luke had yet to start the car, when both of them looked out of the passenger side helplessly.
