Aha, so something very bad happened in the other world’s timeline. I loved the way the movie pre-roll ever so slowly drifted from mundane public health announcement to … terror inducing dread.
Sounds like the two worlds are exploring different tech trees, and one of them is (obviously, I guess) equivalent to our current world? And if not for the benefits both worlds derive from that, they’d have closed off the portal long ago?
This is a really solid show so far.
