More infoThe Traitors Ireland star Faye Brennan has told of the freezing conditions during filming at Slane Castle on the RTÉ show. Now the ‘Faithful’ has lifted the lid on what conditions in the castle were really like for the cast and crew. And you don't think it's going to be cold... all my outfits were off the shoulder and short sleeve, or skirts. “People are coming up to me in the streets, they are leaving really nice comments and sending me really nice messages. It’s so nice to know that the nation is behind you, so it’s incredible.”The Traitors final airs on RTÉ One at 9.35pm tonight.
