Octavean I get where you’re coming from. I’ve not rewatched season 1 but I have a feeling that if I did there might be the odd clue here and there that ties in with what we are seeing now. Maybe someone will wake up and it’ll all have been a dream 😃
So we know Alex can mess around with events in time. I was thinking, hmm, maybe Alex was able to cause the cataclysmic event? Maybe they wanted to remove humankind from the equation? Sounds a bit Skynet like, but without the killer robots. I had a little dig, and maybe the naming is nod to Matt Smith’s character in Terminator Genisys as they’re named Alex and are a physical embodiment of Skynet. Hmm, maybe that’s what Jane was, a physical representation of Alex? Could explain some of the warnings about them from the past?
