Kayne forgot to mention to Jayson or Chad about the goatee guy that he tied up in the back of the van. He was just so happy that Jayson had finally rescued Chad. Besides the guy was tied up, he wasn't going anywhere. Aristide was Bruno's older brother. He knew what Bruno had planned for Chad, and when Bruno disappeared, he was sure Chad was to blame somehow. His agents soon latched on to Jayson who was searching for toilets- especially one named Chad.
Aristide knew that his brother Bruno had planned to put Chad to use in the boys locker room, and since he quickly determined that Chad wasn't among the toilets there, Aristide suspected that whoever took Chad had also done something to Bruno. He figured he had to get Chad to find out what happened. He had come to at some point into Jayson and Chad's conversation about Rick and Bruno. His brother was a mannequin. Hell, if he had known, he'd've left Chad to rot in the gay bar, and turned Jayson into a practice dummy for his martial arts. There was still time. He just had to get free of his bonds before they did anything to him. Then he'd go to Jayson's house and liberate Bruno, and then he would let Bruno decide how to deal with these three and Todd and Rick or whoever moved the toilets in the first place. Aristide was angry and vengeful. He slowly worked his wrists to loosen his bonds.
