Though this would be a nice ending for the two characters, I think in the legend, Gwen dies without an heir, having never had children [In the legend, she takes Mordred in as her own son, unaware that he is Arthur's son, and cares for him, as she cannot have her own.]. I wouldn't want that to happen, but I guess we have no way of knowing!
