I believe ina day or two should be able to do a post to advance things.
As for the Mayan-Atzek city, the things we know so far are: from it, come warriors that kidnaps five years old metahuman kids; they are "not human" as Sweeter says to Hero, and, as seen of the murals, they share a connection to aliens.
Everything else is open to interpretation. Hero with Sweeter are coming to the city, quinn and Marvelo are there, Midnight is going away, while Doug has been kidnapped by the East-indian-themed villains and that plot (which is connected to the uresolved story of issue 2), could be better reserved to be solved next story.
