However, the episode felt like it had a few cuts. So maybe there was more to the story than we saw. There's an odd jump, where suddenly everyone who was in 2017 (Stein, Jax and Rory) are now back in the '80s on Hallowe'en night, without any exposition to cover how they got back in time to be there.
I can accept this kind of daft plot--especially on LOT--just as long as they cover it with some pseudo-science. For instance, we saw that Ray was at risk of disappearing from the timeline, but that it hadn't yet become a fixed fact. So that could have caused Martin's whole dilemma with Lily. If there's a true fear that time itself can always get rewritten--it's vital to Martin to get there to 2017, to see his grandchild, so he can retain the memory and not lose them.
But Martin might have also created a temporal quandary by communicating with Lily in 2017--that itself might have made it impossible for him to go back to the period of her pregnancy in 2017 without messing up the timeline he had already established with her, through their communications. For both of them that had already happened, so by going back to any point prior to the granchld's birth, Stein could have butterfly effected those events.
