Just because he's not firing doesn't mean Martin is fully relaxed, and as much as he's trying to be polite the stranger's sudden voice still makes Martin startle, and very nearly drops his bullets as he spins around to look like a deer in headlights at the stranger.

"I-I-I, uh-- S-sorry-" He takes a deep breath, and with very deliberate motions, holsters his gun - the holster and its leather straps so neatly hidden under the layers of his kilt-like robes that it's invisible when he puts it away - before he turns properly, looking marginally less frazzled.

"S-Sorry, um. I actually- I got mine from my mentor, I-I think he must have picked his up back in- in Thorne, probably."
