Arthur rested his head in his palms. Feeling he wasn't alone, he sat straight and propped his chin on his fist.

"Hello Merlin."

The servant smiled gently. "Is everything all right, sire?"

Arthur sighed. "Sometimes I don't know who I am. Some days I do, and I don't like it."

Merlin grinned.

"Who would like being a prat?"

Arthur rolled his eyes. Merlin frowned.

"You know who you are."

"And if I don't?"

Merlin blinked. "Well I know you."

Arthur looked up, eyes narrow.

"And… you like me?"

"Course I do."

The king grinned.

"Most of the time," Merlin mumbled.
