He's been mentally broken since MS. Remember that he hadn't been able to ejaculate even by jerking off since MS graduation. If he hadn't ran into them again he'd either have been celibate for the rest of his life or maybe have been able to recover after extensive psychiatric therapy. Running into them brought the trauma to the surface and triggered the old behaviors. He's their slave and he's going nowhere until they dump him.
