I keep seeing posts about how Henry went to the EF, fell in love and had Lucy, and then ended back in Seattle but that’s not what happened. I know it’s confusing since in this show memory curses are so common but Lucy doesn’t know Henry when he answers the door implying that she has never met her father before that moment. The EF sequences were in the future happening sometime after Lucy knocks on his door and A&E confirmed this when they called them flash forwards.
I actually think this signals a shift in the storytelling from flashing back to flashing forward. So we will have one storyline that is Henry and Lucy in the modern world dealing with the new curse/cursed people and a second storyline that flashes forward to the EF and the conflict with this gathering darkness. I think the main thrust of the season is going to be getting us to the point where Henry disappears (or maybe half of the season). We may still get flashbacks for key pieces of information but it won’t be a continual flashback into the characters past.
