Anyway, in original plans, they pretended to make Peter and Gwen the "parents" of Sarah and Gabriel. Since it has been revealed they are clones (as I always suspected), this could actually happen because they could make a new Sarah and a new Gabriel using Peter's DNA and combining it with Gwen's. Ben and Kaine seem to have surpassed the Age Degeneration problem, so they could be the key to create a stable Sarah and Gabriel.
