Red Dwarf - Series VII (1997)

The crew goes back in time to get food but inadvertently lands in Dallas on Nov. 22, 1963, the day President Kennedy was assassinated.

Ace Rimmer -- Rimmer's charming alter ego from another reality -- revisits the crew to ask Rimmer an important favor.

The Red Dwarfers pick up a new crew member -- Lister's old flame, Kristine Kochanski -- when they encounter a wormhole.

Fearing he'll someday be replaced by Kristine Kochanski, a jealous Kryten "accidentally" shuts down the Starbug's engine.

Lister is conflicted when he discovers that he actually misses Rimmer, who's been away protecting the universe for far too long.
