The résumé lists the character name as “Roslyn Frey” but it may be a spelling error, or a minor change for the television series. Her agency CV lists her as joining Game of Thrones, but without specifying the role. A newsletter from Dowling’s alma mater refers to her GoT part as a “cameo.”
Dowling is a 2012 graduate of the Oxford School of Drama. She recently filmed an episode of Merlin as “Kara,” and will be playing the female lead in the film Hammer of the Gods.
In A Storm of Swords, Roslin is the fifth daughter of Walder Frey, the Riverlands lord played by David Bradley in season one.
