Torvi and Riddick Friendly was a foreign concept to Riddick. People treated him like a pestilence when he was a boy -nothing more than a ward of the planetary alliance- and they treated him worse when he moved from the designation of 'ward' to 'convict.'
No one wanted to associate with convicts. Even other convicts didn't want to associate with convicts. Riddick sure as fuck didn't go around trying to make friends while he was in a slam.
For him, every slam was only a stop on the map for him. He never had any intention of staying where he was put. Riddick wasn't some good dog. He was only able to settle in at Madison because there was no other option.
No one was getting out of Madison. The Dome made sure of that.
