Bronn ended Season 6 arriving back at the capital with Jaime Lannister to discover the destruction of the Sept of Baelor; evidently, he won’t be leaving the region right off the bat in Season 7.
James Faulkner isn’t the only Game of Thrones actor who has been spotted in Cáceres.
Season 7 seems to be bringing everybody else together from all corners of Westeros and even Essos.
Maybe Bronn and Randyll will cross paths while in the same area.
