This was the first time Luke commanded a capture operation, and to ensure everything went smoothly, he didn't act rashly.
After getting out of the car, Luke circled to a spot not far from the suspect's house to observe. The two black boys were constantly around the suspect's house, and there was nothing fun nearby, which seemed odd for two lively kids. Luke became increasingly convinced they were lookouts.
Luke's plan was simple: first capture the two black boys and interrogate them about the suspect's situation. This would maximize the safety of the capture team.
It was his first time leading a capture. He didn't seek credit, only wanted to avoid mistakes. So long as he didn't mess up, there would be another opportunity. If his mistakes led to injuries, even if Jack was keen to nurture him, future chances would be weighed carefully.
After a while, one of the black boys rode away on a bicycle, leaving the other to keep watch near the suspect's house.
