He looked up at the wall in fascination as they approached, mind quickly working on problems of constructing such a monstrous structure. It was a marvel of engineering. Especially as it was constructed of nothing but ice, as far as he could see. It must never thaw in this place. A cold, miserable existence. He repressed an urge to run a hand along the tunnel wall as he passed. He did not need to add frostbite to his problems. Not that his fingers couldn't be reconstructed properly, but it would be an inconvenience. He chuckled softly at Tyrion's reply. "I can handle my self in a fight," he said dryly. He had both a gun and his sword, he wasn't worried at all.
