The epilogue is a wrap-up of the intro and the intermezzos and shows Tommy Angelo finishing his story to Detective Norman and saying how he took his wife and daughter and fled the country. Norman reveals to Tommy that he will help him, before switching to Tommy sitting in an isolated cell and writing down his testimony about all the people he had worked with. He says he was imprisoned for eight years and released in 1946 and then re-united with his family before getting new identities for him and his family and moving to Empire Bay, where Tommy got a job as a driver for Empire Bay Cab & Co..
Next, Tommy is seen watering his front lawn outside of his residence on Oak Street in Empire Bay. Suddenly, a Bolt-Thrower pulls up and two men dressed in suits step out. They walk up to him and one of them asks him "Mr. Angelo?" before Tommy responds "Uhm, yes?". Next, the hitman says "Mr. Salieri sends his regards" and the other one pulls out a Sawed-off Shotgun and shoots Tommy in the chest. The two return to their vehicle as the camera zooms out while Tommy narrates a speech of how he, Sam, and Paulie just wanted a better life but were worse off than most other people:
"You know, the world isn't run by the laws written on paper. It's run by people. Some according to laws, others not. It depends on each individual how his world will be, how he makes it. And you also need a whole lot of luck, so that somebody else doesn't make your life hell. And it ain't as simple as they tell you in grade school. But it is good to have strong values and to maintain them. In marriage, in crime, in war, always and everywhere. I messed up. So did Paulie and Sam. We wanted a better life, but in the end we were a lot worse off than most other people. You know, I think it's important to keep a balance in things. Yeah, balance, that's the right word. Because the guy who wants too much risks losing absolutely everything. Of course, the guy who wants too little from life, might not get anything at all."
