I could get on board with the EvilDarlings theory. That’d be fun and twisted.
I think there’s gotta be some go between for THO in our world. All their equipment worked while in our world, that walkie talkie would have had an actual battery that they’d charged multiple times, it just disappeared when they got to NL. So all their stuff was real world stuff, and I think there had to be someone in our world who they actually communicated with, and that’s the person who spoke directly to PP. There had to be someone in our world to have recruited GOAT in the first place.
