The next day Monica is going laundry when she discovery's bus tickets in David's jean pocket. Across the street, an ambulance appears to pick up a recently deceases neighbor. Monica sees her friend and fellow angel Adam who is on the scene to help escort the neighbor to his 'reward'. Monica asks Adam if he knows anything about the Morrow family and if he knew anything or the death of the mom and baby sister. Adam says only the little 8-month baby girl was taken while in her crib, so the mother is still alive. Upon this realization, Monica finds David at the bus depot and asks him what really happened. Mrs. Morrow ran away to the desert after the death of his baby sister Katie. Monica promises she will find his mother for him and goes to the police station to asks Mr. Morrow for some time off for an emergency. Monica overhears Mr. Morrow talking about going to the Dead Dog Saloon to interview a witness. Monica asks where David's mother and he says she is at a place called Hewitt. At Hewitt, Monica is seen by 2 waitresses talking to an invisible Tess who chastises Monica for leaving David. They argue and Monica claims she is following her instincts by trying to find David's mother. Tess takes Monica's place as David's nanny. The two waitress, Ruth Ann, and Christine welcome Monica into their gas pump. They think Monica is running away from a man because she has no purse and exhibits strange behavior They and introduce Monica to coffee and she just smells it. Monica claims that she wasn't allowed to stop and drink coffee and this is a real treat. Monica asks for room and claims she doesn't have too much. The waitress says she can help work it off and Monica says she is good at fixing things. One of the waitresses Ruth Ann is wearing a star necklace and Monica mistakes her for David's mother. Later Monica and Christine are taken down some dried laundry when Monica asks about a red Cadillac. Monica befriends the two waitresses while playing pool and convinces Ruth Ann to take her dancing at the Dead Dog Saloon. She arranges a meeting between Ruth Ann and Nick, which backfires when the police officer recognizes the waitress as a wanted fugitive. Ruth Ann runs away in the Cadillac leaving Monica behind. Ruth Ann returns home long enough to get her things and explain herself to Christine. Ruth Ann has been running from the law because of an accident that left somebody dead a long time ago. Ruth Ann gives the star necklace back to Christine as she had only been borrowing it. The angel appeals to Ruth Ann to stop running, but she refuses to turn herself in. Returning to the café, Monica discovers the other waitress, Christine, is actually David's mother and reveals herself in an effort to persuade the women to return to her family. But Christine blames herself for Katie's death and refuses. In anguish, Monica tearfully prays for guidance and returns to David and Nick to deliver the bad news. The child is crushed, and Tess admonishes Monica for mishandling of the assignment. While Nick is outside comforting his son, Christine drives up in her red Cadillac, Monica's revelation convinced her to return home, thus reuniting the family. In gratitude, Christine gives the angel's her car, which Tess gladly accepts.
