William "Billy" Brodie was the brother of Jack Osborne.
In 1968, Billy attacked Callum Alexander and forced Jack to join in, and Jack ended up delivering a fatal blow. Billy was arrested and charged with murder, and sentenced to life imprisonment inside Eastbridge Prison.
In September 2016, Billy contacted the Osborne household several times without leaving an answer via phone. He then requested to see Jack. Jack eventually ended up visiting him. Whilst in prison, Billy suffered a heart attack in prison. Jack assumed Billy was faking his heart problems. Billy told Jack that he wanted £5000 for his silence but Jack leaves in disgust. Billy's daughter, Eva Falco, visited Billy in hospital and told Billy to forget about Jack. Shortly after, Billy died from heart failure.
