THEY COULD... thankfully he's not quite obsessed with apocalypse matters (just kind of along for the ride) ... though he does give his best effort in trying to stop it

the canon point he's taken from, he time traveled to 1960 right before the apocalypse happens and has been living there for 3 years.. he doesn't know the rest of his family are there and that there is a second apocalypse coming that is going to hit not long after jfk gets assassinated, soooo ...

he thinks he's in a safe place tbh
