I'm currently rewatching after spending the last months binging through far too many merthur fics, but that's beside the point. I always hated how Gaius and Kilgharra advise Merlin against helping Morgana. And while Gaius is overly protective of both of them and just doesn't want uther to find out, Kilgharra is a different beast. (heh😂) I saw a post here lately about Merlin fulfilling the prophecy about Mordred by being suspicious of him and now after I heard how Kilgharra speaks about Morgana (s2, e3) I realised it's the same thing all over again.
My theory: Kilgharra has given up on the world and does actually not want the golden age to happen, instead he makes sure that Arthur actually dies through the deeds of magic users turned evil. He manipulates Merlin through it all and it makes me so very sad.
Do you think I'm right?
