User blog comment:Morganaforever/Series 5 fights/@comment-4135736-20120302130639

I would love to see a duel between Morgana and Merlin (old or not, I don't care because he showed great agility when he fought the Knights of the Round Table as an old man, the first Morgana and Merlin fight contradicted that), Mordred and Merlin and maybe Morgana and Mordred vs Merlin. I hope these magical battles are an improvement to those terrible duels involving throwing people and objects about. The most likely reasons to make Mordred want to kill Arthur is because in Series 2, Arthur led two attacks: first on the Druid camp (The Nightmare Begin's) and second on Alvarrs hideout (The Witch's Quickening), both the people who Mordred was staying with, that would drive him to kill Arthur for revenge. However, don't forget that Arthur would not stand a chance against Mordred if he does not have magic himself, so maybe Merlin will disable Mordred's powers like he did with Morgana so that Arthur will fight Mordred, though I don't know if that will happen in Series 5. I'm not sure if there will be a battle between Aithusa and Kilgharrah at all.
