User blog comment:Rod12/The Unknown Returning Villain for Series 5/@comment-4650675-20120309122538

What I think is, we'll never see Nimueh or Morgause again, maybe only some references of them now and then. Alvarr- there is a high possibility he will return, same for Mordred. I also have an idea or two of how they will appear, since we will have "more Arthurian Legend" is series 5. Mordred and Alvarr would be guests to Lot's kingdom (there were some references to him so I think it's time for him to show up) and Morgana goes to him to form an alliance, which ends with Morgana reuniting with her former friends. I think that this makes a lot of sense, since Mordred was originally king Lot's son, so those references MUST have something to do with Mordred. It is a smooth and nice way to bring him back. I also agree with below comments, if Alvarr appears he would probably sacrifice himself to pay back Morgana for saving him. Finally, I really want Odin to appear so that he finally dies-he is such a coward! All he does is send sneaky people to try and kill Arthur. Time for him to go on an all-out war and die, or sign peace and mean it.
