Hi! So. Undiscovered Country!

So like, that white dude is a double agent? Ace's coin showed that like, time in the US is horribly skewed? So how will white boy double agent and sister find their parents if like 100 years have passed? Do we know he 'purchased' the right coin back? I'm confused. I want to like the series but the characters swing between too complex and not enough information to embarassibly obtuse i.e. Ade "why do you even care so much, white girl?" White girl: because.... I have reasons

Also, what happened to Uncle Sam and America Man? Why isn't Uncle Sam like, dead, if a trizillion years have passed, yet the siblings still remember him?

I can't remember their names lol. I think Alan Moore said that six characters is the absolute maximum you can have without confusing everyone. I don't know how many 'main' characters this comic has. But I feel confused.
