Although of a low and undistinguished birth, Hugh of the Vale somehow became squire to Lord Jon Arryn, Lord of the Eyrie and Hand of the King. On Lord Arryn’s death, he was knighted by King Robert in honor of his deceased foster-father. He is a young man, described as not handsome, with rough-hewn features. He has a notable ego, following his knighthood.
The actor cast in the role is 3 years older than the character. More notably, however, his name has been changed from Robert, named after the king who had been Lord Arryn’s ward, to Robin to avoid potential viewer confusion.
Jon Arryn’s former squire proves arrogant when Jory Cassel comes around to ask questions, insisting that as an anointed knight he’ll only speak to Lord Eddard directly. Ser Hugh never does so, however, as he is killed by Ser Gregor Clegane during a joust.
