I don’t know who this guy is. From the past, present, or future. As long as he doesn’t work for the Home Office I’m sure he’ll be an interesting addition to the show.
Personally, I’m hoping his story is connected to August’s story. I’ve been waiting to hear a believable explanation of how August found Baelfire, and why he typed that message on his typewriter.
Those incidents happened in our world, and since Emma is back in our world, now would be the perfect time for an explanation.
Theres a shot in the promo of Emma reading something. I hope it was written by August.
