Well, Naho pregnancy is actually a bit intresting, as we're not quite sure what she can birth. There's apparently no previous cases of dragons impregnating moon-touched wolfgirls. And if you give Naho to Malagar, he'll conclude that moon-touched don't actually have moon power in them, but something closer to primal energies.
She will still most probably birth kobolds, but maaaaybe not?
As for her potential role of consort/queen, then yeah, I'm a bit sceptical too xD. I'd love to see her more like loyal bodyguard (her and redeemed Maelys, nice) or maybe even 2nd in command.
