Kenneth Kirk is the father of Colin Kirk and the man Paddy Kirk believed to be his father until February 2019, when Paddy's mother Barbara's affair with Bear Wolf was revealed, and a DNA test revealed bear was Paddy's father.
When Paddy and his brother were children, quick tempered Kenneth emotionally abused him. Kenneth was later admitted to a mental hospital, and when he got out, Paddy made him a poster saying "Welcome Home Dad". Kenneth was over the moon and gave Paddy a hug. However, the next day, Paddy heard an engine going in the garage, with a hosepipe leading to the window, and found Kenneth dead in the car.
