You're undercover in the enemy base. He was being held captive, you decided saving him was worth blowing your cover. "If I weren't chained to the wall, I'd kill you", his voice is menacing, almost hurt. "If you stay here... you'll, die", you say. He stiffens when you reach out to something behind your back. Instead, you throw him the keys to his chains. He's confused, mostly stunned. "Why are you helping me?" You don't answer. He has no idea who you truly are, but he knows you just saved him.
