Question: Does Morgana have her powers back? Because it wasn't clear as to how long the poppet that Merlin enchanted will burn and cut Morgana off from her powers.

A far out theory: Kligharrah sent Aithusa to save Morgana because she is part of the 'destiny'! The dragon did say that Morgana is 'the darkness to his light; the hatred to his love', and so to keep things in balance, Morgana needs to live until the prophecy is done: Albion is united, even if it is at the cost of Arthur's life when Morgana allies herself with Mordred to spell the King's doom.

As for who held Morgana captive, I don't know because there are many possibilities.

I really hope neither Morgana or Mordred is a Dragonlord/lady. It would be really frustrating because we had an entire episode about how Merlin is the last Dragonlord. If this turns out to not be true, it would be as annoying as Mordred being another 'enemy within the walls'! In other words, besides Merlin, Kligharrah has the authority to control Aithusa.
