The Southbound Bus

S1, E1: In the premiere, the angel Monica (Downey) is excited at being promoted to the job of caseworker, a notch up from search and rescue missions, which finally gives her the chance to be seen by humans. Her first assignment is to stay close to David (guest star T.J. Lowther), a 10-year-old who initially appears to be a runaway, riding alone on a bus in the desert and pilfering tips from a pit stop waitress.
