For those of you interested in a good piece of fan fiction, check out "Ship Wars AU" by Moringmark. It involves two separate future timelines: one where Starco gives birth to a daughter (Elizabeth), and another where Jarco gives birth to a son ("Jam"). They each come back to the present to try and fix the timeline anomaly without getting themselves deleted from existence. As of this writing, it is an ongoing story (still being written). Be sure to read the notes on the first page before getting started.
