It wasn't the fact that merl had spoken to him so rudely, Or even the fact the he had been struck that bothered Artus. He was bothered by the way he was being looked at by everyone as if he were some defenseless child. He thought about all the training he had been through and about how he was regarded as somewhat of a Sidhe. When Artus heard the unseen voice, he felt its presence, which cause his thoughts to spiral out of control. Artus became covered in a blue ethereal energy and his body was ripped in half, the same way he was when he was killed. Then the energy went into his body, and Artus grew into a grown man, and his body reformed itself. Artus looked around at everyone, not yet realizing that he had changed.
