"Game of Thrones" star Jerome Flynn plays Ser Bronn of the Blackwater.

At HBO's red carpet premiere for the eighth and final season, Flynn tells INSIDER that his filming experience wasn't as "stressful or strenuous" as his fellow cast mates' grueling production schedule.

Flynn also says fans "might not love [Bronn] as much as they do right now" when asked how people will feel about his character after season eight.

"Game of Thrones" fans may need to prepare themselves for Bronn's character to take a turn for the worse on the eighth and final season of HBO's hit series.

"I don't know, they might not love him as much as they do right now," actor Jerome Flynn (who plays Bronn) told INSIDER at the New York City final season premiere red carpet Wednesday when asked what people will think about his character after the finale.

"But I hope they still do," he continued. "He is who he is and what he says, isn't he? And he'll do what he needs to get his castle."

Bronn's character started out as a sellsword, and quickly rose through the ranks of King's Landing thanks to his service to both Tyrion and Jaime Lannister.

At one point, Cersei managed to wheedle Bronn into doing her bidding by arranging his engagement to the highborn Lollys Stokeworth, and then Jaime promised him a castle for his work. That was back on seasons four and five, and Bronn has yet to get his castle.

Last we saw the wry sellsword, he was working for Jaime and had helped arrange a meeting between the two Lannister brothers. But then Jaime left King's Landing to head north and Bronn remained in the capital.

While other cast members have said shooting the final season was a grueling and strenuous schedule, Flynn had a different experience.

"It wasn't that stressful or strenuous for me," he told us with a sly smile. "Yeah, that's all I'm saying. I wasn't that stressed or strained."

Does this mean Bronn won't have a major role in the Great War heading quickly to the people of Westeros? We'll have to wait for the eighth and final season to unfold to know what Flynn means, but it sounds like fans of his character should prepare themselves for the unexpected.
