There honestly isn't much more left to the story.
Can you stretch it into 3 more seasons? Sure.
But can you also do it all in one? Yep.
In the comics after getting to the point it got to in the show, the shit becomes extremely slow burn.
Don't get me wrong, the comic is still so dope I'll read all those slow ass chapters with all the enjoyment of the world, but I can also see why that wouldnt work for a TV show.
That said, the season needs at least 12 episodes. If they give us 8, it'll def feel rushed.
