Arthur walks down the stairs into the courtyard. Gwen is by his side. She isn't pleased: "Arthur, please. Don't go there! I remember, what happened last time you have been there." But she can't change his mind: "Gwen, I have to. I need to know, what happens here. I have to ask them." He looks over to Sir Galahad and Sir Leon: "Ready?" Both nod and jump up their hoses. Gwen takes her husband's hand: "Please, be careful. Arthur, promise me." He smiles: "I promise. Tomorrow afternoon I'll be back. Tell Gaius, that he has to keep Merlin alive." He jumps up his horse. Together the three men ride out of the courtyard.
At sundown, they reach that cave. As they walk towards the entrance, Arthur pulls his sword out and hands it to Sir Leon: "Take it. And Sir Galahad? I want you to make fire. I'll be back in some minutes." Stunned both knights watch their king. Sir Leon holds him back: "You can't go in there alone! I'll coming with you!" But Arthur shakes his head: "This is something, I have to do alone. " He leaves his knights and disappears in the cave. His knights stand there and watch him unhappily.
Merlin runs along the wall. As he notices a light, he runs towards it happily. As he comes closer, he recognises a bright but blurred place. It is a door but it isn't. Merlin remembers that place. A man makes a step out of it and walks towards Merlin. It is Lancelot. This is the door, what connects the worlds. It is the torned veil, who links both worlds. This is the door what links the world of the dead and the world of the living. But he should be repaired. Merlin stops in his movement: "Lancelot, what happens? The veil, why is he torned?" Loncelot walks towards Merlin: "I decided to open it again." Merlin shakes his head: "That is impossible!" Lancelot smiles: "Is it? Have you been there or me? Why do you know that it is impossible?" Merlin shakes his head again: "I thought it needs a sacrifice to open the veil." Lancelot laughs loudly: "You thought. You also thought that I sacrificed myself willingly. But you left me no choice with your ramblings about loyality. You told me all that, to make me sacrifice myself. I was so supid." Merlin scares: "That isn't true. A lie, a lie! I wanted to take Arthur's place and you knew that. I never had thought about sacrificing you!" Lancelot stands in front of him: "Didn't you? So you wouldn't sacrifice a friend for your king? So why did you sacrificed the Great Dragon? Or Will? Didn't he died for Arthur? Or Isolde? Why didn't you tried to save her life? Because Arthur had recognised, who you are? You are nothing Merlin. I thought, that you are my friend. In truth you sacrifice one friend after another for you and your king. And for what? For nothing! He already left you alone! You are alone Merlin, alone." Merlin walks backwards until he feels the wall on his back again. "You aren't Lancelot. He never would have said that. You are just an imagination!" But the knight calls: "Are you sure? I've always been your one true friend in Camelot. Why should I lie to you? Arthur left you and Gauis has given up." Merlin breaks down, he falls on the ground: "I'm alone. I'm alone. Alone." Despaired he closes his eyes.
