This man and his retinue comes to a bridge over black, devilish, water and think they see two lions tethered to a large rock, but that turns out to be an enchantment. In an early episode, this hero foolishly ignores the advice of a maiden and sleeps in a bed; at the stroke of midnight a lance with a blazing pennant falls onto the bed and nearly burns him to death. Later on, he uses his bare hands to remove iron bars from a cage which causes him to bleed; he then makes love with his lady while bleeding, leading Sir Kay to be accused of adultery.
