The old seems pretty cagey. Cedwyn can't see anything glaring, so he questions him to look for holes.
Cewyn holds up his hand to forestall Rodric's command. To the old man he says, "How came you by this key?"
The man nods, apparently impressed. "The last knight they drug out of there struggled. One of the guards had their head dashed against the wall and fell senseless to the ground. When they dragged him out of here, I noticed a key had fallen from him, so I hid it in the filth." He shakes his hands indicating his short shackles. "I cannot use it, but I can toss it to you."
To Rodric he says, "I am an old man, and no warrior. I would never make it out on my own. With your help, I stand a chance. I will give you the key, if you swear to help me. I know Cymric knights are men of their word. Will you give me your oaths?"
