I ' member . <| sep |> Greyscale is a disease . Wights and White Walkers are immortal , with some being thousands of years old , so its safe to say that they are immune to disease , greyscale included . Stonemen are infected humans . Any human can be turned into a wight , no matter what diseases they have , and any wight has a weakness to fire . Therefore , a stoneman should be able to turn into a wight and catch fire like any other wight . Wights shouldn ' t be able to get greyscale . <| sep |> have you seen a war by any chance ? a lot of people involved would be young and unmarried , butchered by the masses . in early rome , the army ' s first line was the Hastati , basically a bunch of young peasant men trained to fight and sent out . they were the first ones into the melee of the battle and would whittle down the enemy for the next , older line to come in . as time has gone on war has generally become more and more focused on younger soldiersyes , marriage happens a lot , but im not specifically talking about murder on the street . im talking about humans killing one another in general .
