I can guarantee Lancelot will return in some way, as he was seen in the trailer. I think he will be revived by Freya in a second repayment to Merlin (I'm pretty sure it was him who rose from the Lake of Avalon.) Other Characters: I don't think Morgause will return in a MORTAL way, but she will appear to Morgana in some strange way. I think Mordred will return towards the end of Series 5, because there is little storyline you can adapt with his legend. I think Alvarr will return in the same episode Mordred does. I honestly think Nimueh won't return for the rest of the show, but I certainly hope she does. Some of you may notice a minor villain called "Odin" who made an appearance in Series 2, I think he will have big impact in future episodes. Alined, Vivian, Olaf and Trickler may make a cameo in the future but there won't be any storyline to do with them. I think Hunith will make a cameo in the future. I think Gilli will also make a cameo in the future. And I think Grettir will never appear again, but there may be other dwarves the appear. Ygraine will appear in some way.

Well... Sorry to change the subject but there is a list.
