Assuming you’re up to date with Game of Thrones Season 7 you’ll know that Jon Snow and Daenerys Targaryen are working together in an uneasy alliance.
Daenerys has given Jon permission to mine the dragonglass that’s buried keep under Dragonstone, and Jon has wasted no time in getting to work.
Suffice to say this clip isn’t what appeared on the show. Instead, it has been edited to make it look as though Jon Snow is a noisy bugger.
It’s masterfully done, with the characters pausing at the right moments, and looking thoroughly pissed off with the racket Jon is making beneath their feet.
