Ianto Jones' father

Ianto Jones' father had not a good relationship with his son. Ianto told his Torchwood team that his father enjoyed taking him to the cinema, (TV: From Out of the Rain) though his sister Rhiannon implied that their relationship was not as strong as he made out. Rhiannon and Ianto recounted that his father pushed him too hard on the swings in his childhood and broke his leg. (TV: Children of Earth: Day Two) In the last days of his life, he was hospitalised and waited three weeks for a call from his son, in vain, before he died. (AUDIO: The House of the Dead)

Afterlife
Along with other dead people, he was "summoned" by the entity Syriath in the House of the Dead. He talked with a "revived" Ianto Jones, holding his "betrayal" against him. He tried to persuade him to let Syriath rise, in order to see again his passed loved ones such as his mother, Owen, Toshiko and Lisa. (AUDIO: The House of the Dead)

Behind the scenes
He was credited as "Mr Jones" in The House of the Dead.
