This theory post contains speculation for Game of Thrones Season 8, episode 3, and spoilers for episode 2, “A Knight of the Seven Kingdoms.”
If there’s one Game of Thrones character who’s shown a real knack for making his way in the world and playing the War of the Five Kings to his advantage, it’s Bronn. This once humble mercenary has managed to work his way up the ranks, befriending the Lannister brothers, earning the title “Ser Bronn of the Blackwater” and even becoming the only person in living memory to wound a dragon.
The Season 8 premiere suggested Bronn might play more of an antagonistic role in the final season. Bronn has been dispatched to Winterfell by Queen Cersei, ordered to kill both Tyrion and Jaime. But maybe the question shouldn’t be “Will Bronn betray his friends?” but rather, “Is Bronn the key to saving Westeros?” Here’s why we think Bronn may turn out to be one of the most important characters in Season 8.
