Haha, me again. =)

Unfortunately I dont own the characters, the BBC does. Even though, in my opinion, they're doing it wrong.

There was no way Merlin was ever going to get that image out of his mind. It had all been going so well and, even using all his magic, he would never have seen this coming.

True, he hadn't been overly happy when Arthur declared he was in love with Gwen, but he had accepted it. He was happy for them, understanding that he could never be what Arthur needed. Merlin had grown used to the idea that Arthur and Gwen were going to be together for the rest of their lives and he was just going to have to settle himself in the 'best friend' position. It wasn't that bad. Not really. After all, Gwen was his friend too.

But not anymore. Not after this.

Arthur didn't know. He couldn't know. This would kill him, Merlin was sure of it. How could he have let this happen? Why didn't he see it coming? When Lancelot returned to Camelot all smiles and charm, he should've known it would end badly. He should've remembered Gwen's attraction to Lancelot when they were younger.

But Merlin hadn't known, the thought hadn't even crossed his mind. And now it was too late. Sooner or later, Arthur was going to see the same thing Merlin had just seen.
