Merlin grinned and hit the little white poof at the end of his hat. "A Santa hat. There is a story of big man in a red suit who gives gifts on christmas." He liked the hat. It was soft and amusing, and it got a smile out of Lancelot.
"That's alright. You're here. That's what matters." He looked a little concerned because Lancelot didn't appear in the best of moods. Merlin remembered their last chat though, and assumed it was because of Gwen and Arthur. "Do you want a hat?"
Merlin dug a hand into his pocket, pulling out a brightly colored Christmas cracker. The tubes were wrapped in paper, and would pop when opened, usually giving you a paper hat of some kind. "Take the other end and pull."
