Faithful Protector is a companion perk in Fallout: New Vegas. It becomes available to Rex if Rey's brain is used in the quest Nothin' But a Hound Dog.


Faithful Protector increases Rex's attack damage by 25.

Quick walkthroughEdit

There are three options for retrieving the brain needed to unlock this perk:

  • Just walk in and kill Rey. This option turns Old Lady Gibson and her other dogs hostile if the player character is not hidden while doing so.
  • Talking to Old Lady Gibson will reveal an option to give her money, in which she will take Rey off to the side and kill him in private; giving you the brain afterwards.
    • Alternatively, you may pass a Barter check of 70, in which case she will do this for free.
