Just yesterday I completed watching season 4 of The Man in the High Castle and had a burning question throughout the entire season.
It could be a plot hole, or it could be I missed some vital clue.
At the end of season 3 Juliana manages to travel to 'our' world just as Smith shoots her. But minutes before that cliffhanger scene, we also learned through Abendsen that one can only travel between worlds if your counterpart in the other world is dead.
But Juliana in our world isn't dead. Juliana in our world is married to Tagomi's son and they have a child (season 2, episode 5)
How could Juliana have travelled to our world?
