Brotherhood Bond

 is an unmarked quest in Fallout: New Vegas.

Quick walkthrough
Located in the Hidden Valley bunker, home to the Brotherhood of Steel, the goal of this quest is to gain reputation with the Brotherhood.

One way of achieving this is completing the quest Pistol Packing, in which you are asked by Knight Torres of the Brotherhood to retrieve the Missing laser pistol.

Upon return the player is greeted by an Initiate who lets you know about a supply of recycled energy weapon ammunition, to be restocked every day!

Keep being helpful to the Brotherhood, and it will begin to really pay off. Complete the quest Still in the Dark and you will be given the Brotherhood of Steel safehouse key, gaining access to a safehouse where the player can rest and relax.
