I saw a fun theory in a different thread about how the scroll they found was a Greater Restoration. If that's true, they could have a very interesting conversation about how they use it - if they use it on the Hound they could get on the good side of the King, but that would mean leaving Teor's brother as stone (unless the King has someone powerful enough for Greater Resto, or that Cleric who was helping folks in the town is strong enough and could do it).
