Brother James

Brother James is scam artist living in the Commonwealth.

Background
Upon meeting him, James will invite the player to join the movement. If you tell him you're interested, he'll ask you to follow him to a private room. Once there, he'll tell you that in order to join, you must give him everything you own. You can refuse if you pass a speech check. But, if not, you'll be left with nothing except your clothes and pipboy. If the player refuses to hand over his possessions, James and all of his followers become hostile.

Interactions with the player character
Upon approach, Brother James will initiate the Sole Survivor in dialogue. At the end of his dialogue he will ask you to follow him to his office. In his office, your draw and fire ability will be blocked. Brother James will tell you to give him all of your belongings. At this point you can give them to him, or opt not to.

On non-compliance, Brother James will drop the act and inform the player that their belongings can either be given voluntarily or be taken by force. Opting not to will result in being attacked by the group (about 10 of them). Kill them all and leave the area. Optionally, you can pass a red Speech challenge, which will result in being allowed to leave without any further conflict. He will claim that you're not worth the time to deal with.

If you agree to hand over your possessions, Brother James will take every item from your inventory (but not your companions) and will hold them on his. You are free to go, but the only way to retrieve your items is to pickpocket or kill him.

Appearances
Brother James appears only in Fallout 4.
