The production team had to film in London instead due to the lack of support from the legal authorities in Glasgow.

Junior slashes a father's face in front of his children, shocking Paul due to Anne Marie's pregnancy.

Paul tells Anne Marie he has become what he had always hated and wishes to leave Glasgow because of the slashing incident, and that he wants to turn his back on crime.

He serves eighteen months in prison for possessing a weapon, after which he meets his new son and Anne Marie says she no longer loves him.

Later Junior is brutally executed outside Arthur's home by a masked assailant, who is addressed as "Paul" by the getaway driver.
