We didnâ€™t see Tormund after all the chaos at the Wall, but you can probably assume heâ€™s going to be OK for season eight.
We speculated that possiblyÂ the only way to kill ice ViserionÂ is by killing the Night King. Now that we know if you kill a White Walker all the wights it turned also die, this seems like the most efficient method. AndÂ George R.R. MartinÂ had a kids book in the â€™80s called â€˜The Ice Dragonâ€™, in which an ice dragon totally demolished some fire-breathing ones. So, the task may be impossible without this Night King option.
However, time and time again weâ€™ve seen that everything on â€˜Game of Thronesâ€™ is cyclical. Because of this,Â perhaps Drogon will be the one to kill Viserion, since his namesake, Khal Drogo (Jason Momoa), killed Viserionâ€™s namesake, Viserys (Harry Lloyd).
