Tyrion could detect a hint of amusement in that last statement, but he couldn't be sure as the Northerner's face was hidden between a black greathelm.

Not to mention the unsaid threat of the savage dragon that looked ready to burn down everything in the surrounding area. He highly doubted that a healthy Viserion could match up to the dark-blue monster in front of them, let alone a wounded one.
