“I see you calling my bluff and I resent it,” said Gideon. “So, hey. What do you really use when you’re not pretending the rapier’s your main wield? Two short blades of equal length, or one blade and one baton?”

“You drew your rapier and your dagger at the same time. And you’re ambidextrous. You keep cutting like both your blades are curved. Also, there’s six swords and a nightstick on your bed.”
“Should’ve tidied my mess,” admitted Camilla. “Two blades. Double-edged.”
