Things were getting complicated in Kyle's personal life, and there was no telling what had happened with the family that adopted him. Either way, there was no doubt that tension was involved; otherwise, Kyle wouldn't be acting this way.
Kyle needed an escape more than ever and knew that temporarily leaving Los Angeles would do him some good. He needed to let off some steam, and the only way he knew how was through the gym.
