Still kind of confused with the trade minister's ability/meditation thing to go across realities/worlds. At first, it seemed kind of a meditation aspect, but he confirmed that he has 'powers', and during the time that he was in the alternate world with his wife/alternate Juliana/his son, it looked like he actually disappeared from his own world, as when he came back, Kido was wondering where he went.
And it seems, tapes are/were brought over from alternate reality(ies)? I wonder now if the Man in the High Castle has the same reality traveling ability?
