A shadow with ill intent. Agravaine: Arthur. Agravaine: But as for Lancelot, death's too good for him. Agravaine: Sire...
King Arthur: Now! Arthur rides to the box and Guinevere steps down to take the ring off of his lance with a smile. GWEN'S HOUSE - NIGHT
Arthur removes Gwen's blindfold (her engagement ring on his little finger) and she sees her home covered with candles. Give him time. Guinevere sits in the royal box with Agravaine. I must make Arthur see that. It's Lancelot. Lancelot (whispers): Merlin. Lancelot bows. Lancelot du Lac pulls back and nods to Arthur and Merlin who stare at him, equally stunned. Lancelot du Lac: Thank you. Merlin approaches him and Lancelot wakes, unaffected by the blow. Merlin snickers and tries to cover it up with a cough. Merlin's eyes glow and Lancelot is freed from Morgana's grasp. Morgana appears behind him. Morgana gets an idea. Morgana: And Gwen? She can't bring herself to look at him. She has one last wish for you. This has to stop. What do you know about necromancy?

Agravaine informs Morgana, who brings back Lancelot's soul under her command. After Gwen agrees to marry him, Arthur celebrates a tournament and Lancelot appears in the middle of it, with a made up story about his return. Merlin is suspicious because Lancelot has forgotten Merlin has magic. Lancelot gives Gwen an enchanted bracelet from Morgana, to revive Gwen's love for him. Merlin discovers Lancelot's a Shadow, invoked by necromancy , working with Agravaine and Morgana, but can't stop him. Agravaine makes sure Arthur sees Gwen kiss Lancelot. After Lancelot and Arthur fight, Agravaine advises Arthur to kill them both. Arthur banishes Gwen and Morgana orders Lancelot to kill himself. Before burning his body, Merlin wakes Lancelot one last time. Lancelot, now himself again, thanks him.
