(changing my mind about not having my wings, let's just assume he had them hidden under his vest as per usual)
*hearing the repeated gunfire and fighting outside Martin tries speaking to the guard outside his cage*
"Sounds like someone's having a bad day, how long do you think it'll be until someone knocks down that door and frees me?"
Man 2: "Shut the hell up, nobody in their right mind would try to rescue an abomination like you."
Martin: "Then what do you call the noises outside? It sounds like somebody is attacking your camp trying to free us."
*Martin groans in pain as the guard fires a round through Martins wing membrane*
Man 2: "Then you'd better hope that if someone is in fact wasting their time trying to free you, that they get here before you bleed out."
Martin: "You're dumber than you look and believe me that is saying something. You might have chained me up but you left the lock within reach of my claws...and using wrought iron instead of hardened steel to restrain a dragonhound...poor choice."
*the chains fall to the ground around Martin as he gets up and lunges at the door, throwing the end of the chain around the guards neck, the guard falls to the floor after having his windpipe crushed as Martin pulls with his full weight*
-Martin smirks as he scolds the dying guard: "One would think you'd be more cautious when restraining a wolf, let alone a wolf/dragon hybrid....dumbass, I let you capture me. Thanks for telling me what you did to my brothers, count yourself lucky i'm more focused on saving them than making you suffer for it."
*Martin grabs the keys from the guards waist and unlocks his cage, leaving the room afterwards*
