The greatest warlock, ever to walk the Earth, was hidden in a tree. In a game of hide and seek. With Arthur, who rose out of Avalon. Merlin could have cheated and used his magic to make him invisible.
But that would not be fair.
"Merlin! I do not understand this game! Reveal yourself!" Arthur yelled, walking around the yard like an idiot.
"Merlin! Reveal yourself, or I'll banish you from Camelot!"
"Camelot doesn't exist anymore, you clot-pole!" Merlin yelled, dropping down the tree branch and behind the shed.
Arthur turned, hearing Merlin's voice and started walking around again. Sliding to another part of the shed, Merlin almost started laughing before he ran towards another part of the yard, only to be tackled.
"Gwaine?!" Merlin wheezed, surprised by the Knight's sudden appearance.
"Merlin!" Arthur yelled, running up to the two men, before lightly kicking him. "Found you. I win. Can we play this game again. I enjoy it!"
