I think the Washington Township is secretly some kind of particle accelerator or fusion reactor plant. Perhaps it allows one to travel between parallel universes? Maybe that's what Whiterose showed Angela?
And the tour guide/scientist says:
"I love a great mystery.
And I'm fascinated by the greatest unsolved mystery. Do we see reality as it is? Do I close my eyes and imagine that everything we experience, think, see, and do unfolding simultaneously in a parallel universe? So, how many copies of ourselves exist? And might our mental states be conjoined for better or worse?"
Seems relevant to Elliot.
