Since I’m intent on trying to pin one or more of these new finale actors as CS’s kids, I’m going to say that it’s still Emma and Hook’s child that they adopt. Regina dies somehow, and Emma recognizes how good of a mother she ended up being to Henry when she adopted him and acknowledges that by adopting her own child with Hook. Although, I will say, it makes a little more sense that Henry, being adopted himself, perhaps also remembering his deceased adoptive mother Regina, adopts a child with Violet.
