The premise here is simple, Harry but in the Fallout Universe. this is considering that he has been living probably twice as much as Mr. House, he saw it all. from bombs falling, the Nuclear Winter that followed and the many factions rising and falling, because his home became unbearable to live in, he migrated to the West towards where California once stood..

It also goes without saying that because of how much time as passed his clothes had to change multiple times until he found himself wearing what he currently has now. he still retains his job as a Bartender but jumping from casino to casino, depending on the Caps so long as no one questions his background.
