If there were a 2nd season, I think the points that it could explore would be dan dreiberg, who's apparently in jail for violating the keene act, maybe with ozy winding up in the same jail, their effort together to escape perhaps and foil some other plot
but the dr manhattan plot, i dunnohow that works, he/she is a god, theyve played toying with that ultimate power, and used the excuse for why how he could be present but despite knowing all through all time, was unable to know or control that set of events.
but i think they'd need to distance from tulsa and the character set of the 1st season to flush out something or someone else and make a second season more as another standalone with certain tie-ins.
and i think it'd be best as something returned to not as immediate followup to season 1, but maybe in 5-10 years.
not like it matters anyway
