The returning villian, I think, should be Alvarr. Morgana made two tries at Calemot's throne and got her butt kicked both times. (It's time to give it up, boo.) Alvarr could be a Dragonlord just like Merlin and he may have sent Aithusa to save Morgana. Alvarr helps Morgana regain her powers. Alvarr and Morgana could marry and form their own kingdom with the goal to bring down Camelot. In some Arthurian legends Morgana did rule her own kingdom.
