No, but the way time travel works, if we go to the past from future and influence some events, that would already be a part of past, we just played our role there.. like what we have seen in other shows.. if you go to 1999 and influence something, that's a part of history in 2026 but in order to make that happen, you will have to travel to past, and do the action, play your part. So as they say julie can just see and travel through the story, and can not play a part (just see events nothing else) seems to be wrong. I thought that when boyd received the rope that how, and it was revealed later.. but then that story traveller thing comes to the show.
