History
Bronn, a morally flexible mercenary with a heart of tin — copper at best — entered our lives in Game of Thrones season 1, when he helped Catelyn Stark escort Tyrion Lannister to the Vale. Bronn and Tyrion, both opportunists, quickly bonded, particularly after Bronn represented Tyrion in a trial by combat. After that, Bronn served as Tyrion’s right-hand-man, a position he held until season 4, when he jumped on another opportunity and landed a rich wife.
But that didn’t last. After Tyrion fled King’s Landing, his brother Jaime drafted Bronn into his service. In season 5, the two traveled to Dorne in a failed attempt to rescue Jaime’s daughter Myrcella. Bronn also served Jaime in season 6, when the pair mounted a successful siege of Riverrun.

Status
So far as we know, Bronn still remains in service to Jaime Lannister, although he appeared to be tiring of Jaime’s promises of reward in season 6. With his former master Tyrion returning to Westeros and on a collision course with his brother, Bronn may want to switch sides. It’s not like it would be the first time. At the end of the day, he’ll do whatever he thinks is best for him.
