Racetrack: You know he’s been seeing one of the eights, right?
Hoshi: That bitch!

So is Caprica gonna be like getting dumped and then dating your ex’s mom?
That’s where prequels confuse. Events take place prior but are viewed (produced) after. As far as the relationship analogy, it would be like dating someone and then travelling through time to date their mom. Marty did it. I guess that makes it alright.
Which leads to the possibility that you would have been dating your own daughter. Pervert
Retroactively.
