I'm going to guess
Yeah weird things can happen in time travel stories. But I'd be surprised if Jestur writes this in a way that the MC ends up spending years in prison, which is why I doubt the MC is her father even though it's technically possible. Plus that twist would essentially be Jestur nuking his own very successful Patreon since we've already gone all the way with Skylar.
Maccabbee Seemed to be implying Luna thought the MC was arrested at the end of the party, which maybe she did. But at that point MC and Luna hadn't had sex yet, so she couldn't think he was Skylars father but in jail because of that encounter.
