She ought not to do this.

She knows that Arthur sees through her thinly-veiled lies.

Yet she cannot stop herself. Ever since that fateful day any chance she gets; she does it.

He ought not to do this.

He knows that Arthur sees through his thinly-veiled lies.

Yet he cannot stop himself. Ever since that fateful day; any chance he gets; he does it.

Guinevere and Lancelot ought not to do this; but they do it anyway.

Arthur Pendragon; King of Camelot is no fool. He has seen the looks shared between his wife and one of his best knights. They lie to him and the lies are so pathetic that a blind person can see through them. However Arthur brought this onto himself by his actions on that fateful day and so he turns away. He allows Guinevere and Lancelot to believe he is oblivious while they do it. He allows them to slip away from Camelot for hours at a time. He pretends to be oblivious to the looks they give one another from across the room. The other knights are also aware; yet they do nothing. They stand back and watch; the same way they stood back and watched on the fateful day.

"I'm just going to see Elyan." Gwen says as she walks out of their chambers.

"That's fine," Arthur replies; pretending to ignore the fact she's in her riding gear. As the door shuts behind her; he waits and watches as she meets Lancelot in the courtyard and mounts her horse. This time, Arthur follows them at a distance until they arrive at the side of a lake in the middle of the woods.

Arthur stands under the shelter of the trees as a figure appears and walks towards the pair standing at the water's edge. He watches as Gwen rushes towards the man; embracing him like a brother. He watches as Lancelot does the same. It had been the first time Arthur had seen the man since the fateful day and the man hasn't changed a bit.

"I wish you could come back." Gwen's voice, heavy with sadness, sounds over to them.

"So do I," the figure replies.

"We all miss you; none of the others say it but we do." Lancelot adds.

"That's good to know." The figure says.

"We can't stay long; the others suspect." Gwen comments as she turns away; pretending that she's got something in her eye.

"It's fine, someday I'll come back; I promise." The figure vows, squeezing their hands and vanishing into thin air. Gwen wipes her eyes and Lancelot rubs her arm consolingly; the way you would with a child who had just fallen over.

"It'll work out," he reassures.

"No it won't; everything's changed." Gwen retorts, staring at the ground.

"Come on, we'll need to head back to Camelot." Lancelot says, mounting his horse.

"I know," Gwen says as they ride away.

From his hiding place in the trees, Arthur sinks to the ground. Staring at his feet; Arthur knew that Gwen was right. Life in Camelot had changed. It had all changed two months ago on the fateful day.

The fateful day when Arthur discovered the truth and banished Merlin for having magic.
