Meanwhile Sir Lancelot has been avoiding Guinevere due to his feelings for her, but finds an opportunity to distance himself from her when old King Pelles comes to court to ask for their help. He has been usurped by his nephew, while his daughter Elaine has been bewitched and kept prisoner in a tower guarded by a serpent.
