Tommy is still suffering from his time in prison. He gets sucked into a world of his own nightmares having to relive that time. Billy jumps in to save him and what he finds shocks him to the core. He didn't realize how bad things had been. Once they're both safe in the real world Billy decides to help Tommy through the residual feelings and fears he's still holding on to.
This takes place during the episode "homefront". I really liked the episode and the character development from Artemis but I would have loved to have seen a little more to this episode so I've written it. There is slight referencing to my other fic "Broken Allies" but if you don't want to read it this will still make sense. No pairings except SB/MM.
