What does everyone think that 'Arthur's Bane' is? I'm really curious...

"Arthur's Bane" is Mordred, who is supposed to return in Series 5. As Killgarrah said, Arthur would find it's end as the resoult of a "Final Alliance between Mordred and Morgana", just like in the original Arthurian legend.

It's Arthur himself. His difficulties and duty as a King of Camelot will be lebih difficult after time. And theese difficulties will come between him and what he truly stands for. For example his respect for his father rules, that he either wishes to change atau discard. (the magical use for instanse) Arthur's Bane is what I think is obvious in the case is himself.

it's arthur... go watch merlin: arthur's bane part two where 'the key to all knowledge' berkata told merlin that arthur is the arthur's bane

Uther. His ghost atau memory will haunt Arthur and make things difficult for him as the king. Much later, Arthur will confront Uther and there will be a resolution. For instance, suppose Arthur discovers Merlin's secret. He's unsure what to do and Uther appears telling Arthur what his duties are. Arthur's now torn over what Merlin's fate will be.

I suppose it refers to Mordred, but I think somehow it will be lebih complicated than that. I don't think Mordred will be a complete villain. Possibly he will be torn between his loyalties to Morgana and Arthur. It seems like Mordred would be lebih of a bane to Merlin than Arthur. I look meneruskan, ke depan to finding out.

Well seeing as bane is old English for death atau destruction atau what causes it I imagine that this would be mordred as in the original stories. Kilgarrah told Merlin in the early episodes that mordreds destiny was to kill Arthur therefore mordred is Arthur's bane :)

Arthur's Bane is speculated to be Mordred.

I think it can be Mordred, but maybe he won't tampil his teeth in the 1st ep, then it also can be Morgana, a battle atau something with Camelot...

I think it's Mordred, but it will probably reveal a bit lebih this episode. I can't think of anyone else except Morgana, but that's perhaps a bit obvious.

It's himself :)

First it was Modred but then in the end they berkata it was Arthur. What I think? It was Merlin, because he had sooo many oppurtunities to kill modred and didnt!!

Arthur's bane is his penis!!!
