Atlantis sequences

According to the reveals, one Mother Box is on Themyscira, one is in Atlantis, and one is somewhere else on Earth (we all know who has it). If the one on Themyscira would bring a cameo from Zeus, the one in Atlantis would show the history of Aquaman's kingdom.

And, according to the reports, it will be an extensive flashback sequence. Hopefully, they will be merged and they won't take as much as we all believe. Anyway, we can expect some ancient Atlantean kings to make an appearance. And this does open up some new and interesting possibilities.

Thus, if we see how Atlantis was submerged, we could end up with the Dead King Atlan as a main baddie in an Aquaman sequel. Which is more than interesting for me.

However, thus far I have only talked about the flashbacks. And I do get a sense that we don't know the half of it just yet. And this may be too much for a single Justice League flick.
