Brother Simon

Brother Simon is a character in Fallout 4.

Upon meeting him, Simon 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, Simon and all of his followers become hostile.
