I don't think Hope's parents matters anymore.
Hope was another way to have "Jean" without bringing her back. A carrot dangled...and now TPTB are trying to make/keep her relevant.
Another ploy and more than likely, another doppleganger to either go evil or disappear for years in another reality, universe, etc...now that Jean is "officially" back.
