I wouldn't know who it could be. Several candidates have their own preferences: Victoria's ex-husband likes them young, the Monster would destroy her every time they did it and even the Master has a duty to fulfill with the rest of the island and I don't see Brandi as his assistant or partner.
But we still don't know the name or who is Momoko's husband (the Asian woman who came with her family years ago). We also have Monica (the fitness model, who may end up with one of Victoria's children). And even Carmen's possible husband, who has grown up on the island like Gina (we have only seen her have relations with her son in the orgies they have several times on the beach, which makes me assume that she doesn't have one and that, either she is married to her own son or at least has a child with him, as Gina has said about several women having children with their own children).
