afp3683 they're just animation shorts with a vaguely reoccuring themes/characters. don't worry your nerdy little head about continuity and timelines and such.
Aelric i always figured it was simply a reoccurring character in otherwise unrelated episodes. i mean, sometimes the setting was completely different. i remember two that she survived, one had her in the real world to become a soccer mom (seriously), the other sent her billions of years into the future. i say that they have nothing to do with each other.
