"It happens you know Rimmer, you meet people and you move on like" "You'll end up stuck on a spaceship with 'im, 'im and 'im for the rest of eternity" "I'm sick of the Cat, I'm sick of Holly, I'm sick of you, I'm sick of me and as for Kryten...I'm sick of him. I'm sick of this ship,sick of this life, I'm just sick of it" These are just a few quotes that demonstrate the Lister of the early series' frustrations with his predicament and, at times, genuine desire to be rid of the other "boys from the Dwarf". I've no idea how they intend to present him in Series X but the later series seem to show him as having resigned himself to his situation and simplifying his dreams...and yet in BTE he seems, temporarily, happy to leave them behind for a better "life" with Kochanski. He doesn't return because of his "friends" but because of a desire to find the "real" Kochanski. After spending over twenty years on board Red Dwarf with the same people, you would expect Lister to more than a little institutionalised. I wonder if he really would leave them if he got the chance as he once seemed happy to back in Timeslides.
