Kieran was Vince's son that appeared in episode 2 of season 1. He was the only cub left after Vince ate his 5 brothers and sisters. He was the runt of the litter and was taken in by Nelson and after being medically assesed by the Doctor he was diagnosed as "anaemic, asthmatic, he's got athletes foot, Bell's palsy, a bile duct infection, bronchitis, carpal tunnel cirrhosis, cryptosporidiosis, diabetes, dwarfism, Dane Bowers' syndrome which gives him a lovely singing voice, and that he's semi-retarded. After the appointment Nelson decides to prove the doctor wrong by trying to find something he's good at with no success. He can do a jigsaw though. At the end of the episode he is crushed by a bookcase, poor guy.
