Detailed walkthrough

 * Investigate the voice - You'll hear a child calling from a refrigerator near a ruined house south of University Point, east of Jamaica Plain. Upon shooting the handle off the refrigerator a child ghoul by the name of Billy will step out.
 * Talk to Billy - He will inform the player that he had fled to the fridge when the Great War started and that he had been trapped in the fridge for two hundred years. He tells the player that he wants to find his family and return to his home in Quincy.
 * Escort Billy to his house or sell him - You can either choose to help him get there or sell him to a member of the Gunners named Bullet for caps. His house is not far, but there are a few gunners between you and the house.
 * Ending - If you choose to help him get to the house you will find his parents survived the war and are happy to see him. Bullet and some other Gunners will arrive shortly thereafter and demand Billy and his parents step outside. If you choose to fight Bullet, Billy's father will give you 250 caps for saving them.

Or


 * After talking to Billy you will encounter a Gunner named Bullet on the road to Quincy that wants to buy him. Pass his charisma checks for a total of 350 caps, to get the charisma checks you may need to ask him how much Billy would be worth. Let Bullet walk away a little after you get the caps then kill him. When you get the caps from Bullet the quest will technically end, but if you kill him you can talk to Billy again, and then take him to his house for an extra 500 caps from the father, which also bypasses the fight in front of the house.
