Harris, Hubert, and Hamish appear in the first half of Season 5 of Once Upon a Time. After their father passes away, their older sister Merida assumes the throne as Queen of DunBroch; however, the neighboring clans no longer approved of a woman leading them by herself. So they kidnap the boys, and Merida allies herself with Belle to rescue them. The clans aim their arrows at the brothers who are tied to the stake, but are saved by Merida who is able to shoot an arrow through the arrows aimed at them. The three are freed and reunited with their sister.
Emma mentions that they didn't come to Storybrooke, but adds that they are safe and sound by their mother's side.
