Does Lancelot know Merlin has magic?
Sir Lancelot was a Knight of the Round Table. He was one of the first to discover Merlin's magic and was known to be in love with Gwen. Many (including Arthur Pendragon) regarded him as the noblest of Camelot's Knights, especially after sacrificing himself on the Isle of the Blessed.
Arthur was indoctrinated to believe magic led to people becoming power-hungry and evil. All his brushes with magic ranged from annoying to traumatizing.
