Lena Headey vs. Jerome Flynn
Observant fans may have noticed that the show seems to contrive situations so that Cersei and Bronn don’t appear in scenes together, including having Bronn leave the Dragonpit scene in the season seven finale, or using Qyburn as an emissary to send Bronn on his ridiculous mission to assassinate the Lannister brothers in season eight. Persistent rumors have suggested that this is because Lena Headey and Jerome Flynn refuse to work with each other ever since their messy break-up, though Flynn denied this was the case in a Q&A at the 2019 “Con of Thrones.”
