I'm not sure we need to know a lot about the rest of the world and the bigger picture. Our story is focused on this particular group of survivors, so I would say the only things needed to get closure are the agenda and the motives of Ink and at least a hint on how it started. Besides that, it's all about how someone survives in this story of survival. What happened in the rest of the world was never crucial to the story, in fact we got a quick update through Kimmet on that, and that's it. About the families, we know what we need to know on that. Angel was probably someone like Al Pacino at the beginning of The Godfather. We still need closure on Scratch, though, so I guess we can include that in the "families" storyline.
