[SPOILERS S3] Confused about this
I've seen explanations about Noah arriving in 1920, but I'm still confused about the actual mechanics of these trips.
In S3E7, Middle aged Noah comes back from the future and ends up in 1920s, where he meets his younger self and stays at the inn. By that point, the passage is gone and portal is also still not working. How did he travel from 2042 to 1920s.
Similarly, Charlotte and Elizabeth arrive to take baby Charlotte from 2053 to 2042 and later leave her with Tannhaus in 1970. Adam gave them the golden sphere to reach that moment, but after arriving, what did they use to continue to 1970? Did they keep the sphere, use another device or is there some off-screen explanation?
Am I overlooking a detail, or is this one of those events that's intentionally left unexplained
