FULL credits to my dear @mileygoneblogger for this idea, and outside of universe I know this is literally just an offhand joke from a time before rdr2 was even a concept, BUT
You ever think about how, after reuniting with John for just one night, one of the first things Jack asks John is if he’s been cheating on Abigail?
As soon as John tells him about the MacFarlanes, one of Jack’s earliest assumptions is that John’s been messing around.

Sure, this could just be Jack being a teenager making a dirty joke, but idk? He and John are NOT that close at this point.
But, the Marstons’ marriage is largely healthy by this point and we all know Jack has no memory of his childhood. He has no reason to suspect John of anything.
Unless Jack knows about how John spurned him when he was little. And therefore knows about the year John where took off and likely drank and whored his way around. There’s a line where he says “You never wanted me!”— I don’t know how to trigger it but… yeah. Jack knows.
How would he know? He has no memory of shit from when he was four, and even then, at four, he would have NOT understood what that implied.
I think he must’ve heard it somewhere. Did John confess it when they were sorting things out? Was it thrown back at John in an argument (perhaps during the pre-epilogue years)? Did he overhear his parents talking about it? Uncle clearly talks to Jack about wildly inappropriate things– did he bring it up once? Did Abigail ever confide in him about it? They’ve been alone together enough times.
Or was it just an assumption he surmised from John’s behaviour?
Either way, Jack suspects that John’s been fooling around. And I’m ABSOLUTELY reaching here, but considering how quiet he is around Bonnie, which is probably just him being introverted but I mean you COULD read it as Jack having reservations about her. Jack's a huge mama's boy... is he wondering if John cheated on Abigail?
Either way Jack absolutely knows about John’s year of fucking around, and may suspect that his dad’s still fucking around.
This isn’t an anti John post. I love John and I love Johnigail. I also love how human he is and I love the more flawed side of his dynamics with his family.
