User blog comment:Morganaforever/Series 4 Cliffhanger/@comment-4190137-20120218012906

I think the last one, I specified this in one of my blog posts. Why would Merlin send Aithusa? He'd send Kilgharrah, more powerful, faster at flying, simply a better dragon, if he wanted to save Morgana he'd send the "Great" Dragon. Aithusa flying and saving Morgana is too simple, they wouldn't have called it a cliffhanger that affects Series 5 if there wasn't much to it. I think Aithusa isn't evil, as Kilgharrah said, he is the light of the sun. I doubt Mordred has anything to do with this nor does Morgana being a girl Dragonlord. But I am confused on what Katie McGrath said... But I do believe that Aithusa saved Morgana because if it isn't (in the future) for her, Arthur will die, Merlin will fall, and Albion will be gone forever...
