Will Henry’s dad be significant to the development of the story? Nothing is certain yet, but even if he is, don’t expect to hear about him any time soon.

Jennifer Morrison tells TV Line:

I’ve heard rumblings of ideas about Henry’s father and how he fits into all of this, but that is something that is definitely going to take a long time to be revealed.

She jokes that it might be a season 6 finale reveal… but hopefully we won’t have to wait that long! Of course at this point we don’t know if the dad will be significant beyond being someone who fell for a semi-fairytale character, but it’d be interesting if we learned that Henry had some significance to the central mystery of breaking the curse.
