>>138659Fry basically created a time-clone of himself that stayed in the past with his family and dog, while the real one went into the future to meet up with everyone. Bender went back in time to kill Fry, attempted to kill the past fry (this is what turned Seymour to stone) and fry had most of hos hair singed off, becoming Lars (the guy that Leela marries). Lars dies because all time clones are doomed to die, and it strengthens Fry/Leela's relationship.
