Henry's father (people think he's beil, so rump's son and snow's daughter, that really interesting) 或者 august if he alive (I like wood/swan brotp, I kinda wish to see them as romantic couple, but I highly doubt it) 或者 maybe Jefferson (a lot of people 爱情 those two together, I prefer regina/Jefferson LOL)
A lot of candidate, but I think the most possible choice is henry's father, 下一个 season we will know 更多 about emma's past, so I really think we will finally see henry's father, don't think he's emma's true 爱情 though but maybe I change my mind after watching 下一个 season
