It’s from the Game of Thrones series, that’s Ramsey Bolton taunting Theon Greyjoy, and you want to stop watching it quite some while before the final season as the show runners can’t write for shit and GRR Martin hasn’t finished the actual story yet. The beginning is great, though. And so is, so far, House of Dragons, at least for that one the story is finished as it’s a prequel so I’m quite confident it’s not going to turn into a total disaster.
