User blog comment:Rod12/The Unknown Returning Villain for Series 5/@comment-4190137-20120309052623

Well... I do think Mordred will return and he is the villain that they were talking about.

But that doesn't mean that the others won't return. I think we'll at least get a reference to Alvarr, since he played a big part in turning Morgana evil.

As for Odin, I gotta feling they'll conclude his story by saying something like this, "Arthur, I have good news! Odin forgives you!" I think that might happen because for the past 3 series, he has only been mentioned as a villain, so they'll probably conclude his story the same way. But I hope he sets up a battle or something, but I doubt that will happen.

Nimueh, NO! DEFINITELY NOT! I'd rather see Valiant return than her... Her story is over! and now that Uther is dead, her life goal is achieved!

I don't want to see Morgause either, in Series 3 she was the main baddie and Morgana was her sidekick. I was upset when I found out she was returning in Series 4, but I was glad she died within the first few minutes of it. If she returns in Series 5, it will totally not make sense!

To conclude, I think Mordred is the villain that they're speaking of, but that doesn't mean that the others won't return.
