Bullet

Bullet is a character appearing in Fallout 4.

Quests
Kid in a Fridge: the Sole Survivor encounters Bullet who offers to buy Billy. If the Sole Survivor declines the offer (or reaches the Peabody House before encountering Bullet) and delivers the child to his parents Bullet will come to their house with three additional gunners as back up and demands to be sold/given the child and the parents or you'll have to fight them off. The fight can prove to be rather a doozy as the gunners are surrounding you, have numerical advantage, have energy weapons, and will throw a rather large sum of explosives at you.

If you kill Bullet right after the first time you meet him, however, the second encounter with him and three gunners does not occur, but the family thanks you as if you confronted and defeated them anyway.

Locations
After completing the Kid in a Fridge quest, if the Sole Survivor chose to lie to Bullet and tell him that the ghouls are not in the house, you can find him on top of an unmarked dam just west of Walden Pond, and to the north-east of Sunshine Tidings co-op. He will not be hostile until you talk to him or his accompanying Raiders. He can also be found just southeast of the Peabody house but will only become hostile if attacked.

There's also a change that after passing the speech check Bullet will appear just north of Fiddler's Green Trailer Estates with the accompanying Raiders. He is found following a nearby road north, standing on a small bridge crossing a small pond.

Appearances
Bullet appears only in Fallout 4.

Bugs
Sometimes Bullet does not appear at all. You may resolve this by sending your companions away, then fast travel to somewhere near (University Point) to run the script.

PC users can circumvent the problem by teleporting him using this console command: 28db4.moveto player
