Also added to Colby's trauma, the abuse he and his mother suffered from Ross. He tried to do the 'right' thing by leaving it up to the police, even joining the force to help them rescue Bella and bring Ross to justice. But even that failed. He only found them with Dean's help when they went rogue - and they were staying nearby the whole time..he put his faith in the system but time and time again it failed. Even when Bella was rescued, Ross still got away yet again. He kidnapped the girls and was planning on murdering them(Willow was lucky to survive), he was not remorseful and was going to get away with it yet again.
