Now That's Logic

Arthur dropped unceremoniously onto his bed with a sigh, Merlin struggling behind. Without a thought he fell beside the prince, face down.

It had been a long day.

"Merlin," came Arthur's muffled voice, "why is it that every time there's a sorcerer in Camelot, it's the person we least suspect?"

Merlin gave a horizontal shrug. "That's not really true. The person you suspect most is never the sorcerer because it's too obvious, but it can't be the person you least suspect because then they become the person you most suspect. So it can't be them."

Arthur raised an eyebrow. "So it's the person we middle suspect?"

"Pretty much."
