XIII stayed silent throughout the entire ordeal with the old man, but he nearly jerked his hand away from Twain when he started going cold. It was cold to the point that he was having trouble keeping the warmth at the same level. The heat in the room started fluctuating. When Twain came back from wherever he went and let go, XIII pulled his arm away and started rubbing his wrist. If anyone was looking closely, they would see what looked like a minor hand shaped burn on his wrist before his other hand covered it.

"Some other group found me and..." He trailed off and watched the flame in his hand before extinguishing it. "Well, let's just say it wasn't pleasant. So how are you planning on breaking out?"
