Hugh

Ser Hugh, also called Ser Hugh of the Vale, is a character in Game of Thrones. He is played by Jefferson Hall and appears in the first season.

Hugh served as Lord Jon Arryn's squire for four years before Jon Arryn's death. After his death, he was knighted for his leal service by King Robert Baratheon. When Lady Lysa Arryn returned to the Eyrie with her son, Ser Hugh elected to remain in King's Landing in the King's service.

In the books
In the Song of Ice and Fire novels, Ser Hugh is a reasonably effective warrior but is newly-proud and slightly drunk on his achievement of becoming a knight.
