I think I've sorted through the thoughts. We have 3 scenes that take place in the future, 1 at the start of 621, 1 at the start of 622, and 1 at the end of 622. Here's what we learn from each one:

Scene 1 - Henry and his daughter Lucy are living in the Enchanted Forest, during a time of great termoil. Henry gives Lucy the Once Upon A Time book (assumably the one where he wrote the story of Season 1 through 6), and tells her to run and hide, while he stays to fight some sort of evil that comes to the area.

Scene 2 - Lucy goes back to the area, and it appears that it has been destroyed by the evil. Tiger Lily (who appears to be a fairy again) tells Lucy to go to her mother.

Scene 3 - Lucy is riding an elevated train in Seattle, reading the Once Upon A Time book Henry wrote (although the outside looks different), and goes to an apartment where she tells a confused Henry she is his daughter and that his family needs help (obviously this parallels the scene in the Pilot when Henry comes to Emma).

What can we infer from these scenes: As an adult, Henry has a child with someone and winds up living in the Enchanted Forest, and a new evil breaks out. Some sort of curse happens and Henry and Lucy wind up in the Land Without Magic. Henry's memories have been wiped.
