He returns in Series 8, Episode 17. Marty reveals that him and Sue lived happily for years in Spain with their kids, only for Sue to cheat on him with a rich local and kick him out of the house. Not knowing where else to go, Marty flees back to the Chatsworth and begins squatting in a flat once occupied by heroin addicts, and on the run from the CSA for not paying child maintenance. Presumably, he found his mother Carol (who left to go to Maguluf), as he returns with her urn. Shortly after returning Marty causes tension between Shane (Nicky Evans) and Kelly Maguire (Sally Carman) by telling Kelly that he loves her.
