Cait

Cait is a cage fighter and a possible companion living in the Combat Zone in 2287.

Background
Cait was born in 2261 to a distant and abusive family of Irish1 descent. She had tried to run away from her parents twice; the first time, she was locked outside in a shed, the second time, they broke one of her legs. On her eighteenth birthday, Cait's parents sold her into slavery. For five years, she stole small sums of bottlecaps from her owners, until she had enough to buy her own freedom. In a pique of rage, she returned home to seek vengeance on her mother and father and shot them both dead.

At some point after she left home, she began using psycho, developing an addiction. Sometime later, she arrived at the Combat Zone in Boston, and was hired by owner Tommy Lonegan as a cage fighter, soon becoming a strong and ruthless fighter. In 2287, a raider gang moved into the area, which then required Cait to buy friends to make life easier, making the cage fighter mistrustful of selfless offers of kindness.

Sometime later, the Sole Survivor arrives at the Combat Zone just as Cait is winning a match and subsequently interrupts the rest of the event. After the Sole Survivor defeats the raiders in the building, Tommy discusses Cait's drug addiction and offers them Cait's contract.

Effects of player's actions

 * Maxed approval with Cait grants the Sole Survivor the Trigger Rush perk, which increases Action Point regeneration when the player character's health is below 25%.
 * Cait is a potential candidate for romance, an option that unlocks after reaching the highest level of affinity.

Other interactions
Cait can be used to pick locks of any tier. To do so only guide her to the nearest lock. This will take some time, depending on the difficulty. She needs to have bobby pins in her inventory to do so.

Fallout: The Board Game
Cait can be acquired at the shop by any player character that has the Vilified trait. When the player character has her as the active companion and performs a test that uses Perception, Agility, or Luck, she can be exhausted to gain one hit on the test.

When the player character performs the camp action, she will become unexhausted. However, if the player character does not have at least one drug in their inventory, she must be discarded.

Appearances
Cait appears in Fallout 4 and Fallout: The Board Game.

Bugs

 * Cait's quest might not trigger after her confession about her addiction. Taking another companion, sending her back to a settlement, and then talking with her should trigger the quest (it may have to do with her being flagged as a companion). For more info about this bug, read Benign Intervention.
 * Cait will talk about wanting to "lower the dosage" if she thinks she is being followed in combat after Vault 95.
 * During Cait's companion quest, Cait may begin to randomly collapse as if incapacitated during the dialogue. This will continue following completion of the quest.
 * Ordering Cait to pick a floor safe when there is an object between the safe and Cait may sometimes cause her to pace aimlessly around the area.
