The location where LeBlanc and Fiore are picked up is the same as where Walter White, in Breaking Bad S5E14, Ozymandias, is picked up so that he can disappear. After the vehicle pulls away in both shows, the same (or similar) dog crosses the road. Sam Caitlan, writer of this episode, also wrote for Breaking Bad. Michael Slovis, executive producer for Preacher, also worked on Breaking Bad.
