When Hayden visits a shop with Christine and discovers that the owner is none other than Luther's father he is determined to have them both meet. He takes Luther back to the shop and after some coaxing they both start talking. Luther quickly discovers his father did not run away and cut all contact with him as he thought. Instead he had moved each time Luther did, always living a little distance from him and keeping a scrap book of Luther's life.
This makes Luther angry and disapponited and once again it is up to Hayden to make both men work out their differences.
Great episode, introducing someone from Luther's family which is very rare.
