Kid in a Fridge

Kid in a Fridge is a side quest

Detailed walkthrough

 * Investigate the voice: A child will be 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 Sole Survivor 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 them that he wants to find his family and return to his home in Quincy.
 * Escort Billy to his house or sell him: One can either choose to help him get there or sell him to a member of the Gunners named Bullet for caps. Billy's house is not far, but the fastest way there requires swimming to the peninsula with the Atom Cats garage and skirting the outskirts of Quincy, which can attract the attention of enemies in a random encounter spot nearby and the Gunners on the overpass at Quincy.
 * After talking to Billy, the Survivor will encounter the Gunner that wants to buy him, Bullet, on the road to Quincy. If the Sole Survivor passes the charisma checks, Billy can be sold for a total of 350 caps. To get the charisma checks one may need to ask Bullet how much Billy would be worth. Receiving the caps from Bullet will end the quest. If one kills Bullet afterwards they 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.
 * Ending: If one chooses to help Billy get to the house they 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 one chooses to fight Bullet, Billy's father will give them 250 caps for saving them.
 * If they chose to lie to Bullet and say the house is empty (very hard speech check), Bullet and his gang will leave the Sole Survivor and the Peabodys alone. Billy's father will award 250 caps for saving them.

Bugs

 * If this quest is started before the player has encountered Tessa or Clint in Quincy, they will not drop their respective unique items, making them impossible to acquire.
 * Asking Bullet "what's he worth" will freeze the conversation after Bullet stops talking, resulting in the Sole Survivor either staring at him endlessly or having to walk away.
 * When prompted to "talk to Bullet," dialogue may not appear. This can be fixed by reloading or killing him.
 * Bullet may not correctly appear at the Peabodys' house to confront the player. Instead, he will spawn at the center of Quincy, which makes talking to him difficult since Quincy is protected by a large amount of Gunners. PC users may summon him with the console using the command . Otherwise, fast traveling away and back may resolve the issue. Another simple workaround is to kill Bullet on the first encounter.
 * After the quest is completed, there is a chance that some Gunners will spawn inside the Peabody residence. They will not interact with the Peabodys, and if the Sole Survivor kills them it will not be acknowledged.
 * Strong's verbal approval or disapproval is switched with a dislike and like, respectively, for choosing whether or not to help Billy.
