With the new season in sight, I just wanted to discuss this for some reason xD. Every season a lot of new characters are introduced some one-shots, some recurring, so just gonna ask what people expect and hope for the new season. A lot of the new ones are from Arthurian legends so my choices are something that could tie into there.
At the moment we have Arthur, Guinevere, Merlin, Percival and Lionel from the Arthurian legend.
Sir Morgan is an unknown knight of the Round Table and Violet is the daughter of Lionel.
And of course Merida who is the only new character not from Arthurian legend.
Personally I would want to see Bedivere as he always has been a loyal companion of Arthur, but never gets much spotlight. Of course I want to see Morgana too, who I still imagine to be the original Dark One. And my last hope/expectation is the Headless Horseman, of whom I feel just fits in this genre.
