Cait

Cait is a possible companion in Fallout 4. She is a chem-addicted Irish pit fighter and can be found in the Combat Zone. She is able to pick locks up to and including Master rating.

Background
Cait's parents were abusive, distant, and fought constantly. They eventually sold her into slavery once she turned eighteen. She spent five years of enslavement pickpocketing her owners to obtain enough caps to buy her freedom. After doing so, she chose to track down and murder her parents in lieu of rebuilding her life. She began using Psycho after the murder and found herself in the Combat Zone, fighting there for three years until the Sole Survivor kills the nearby raiders and is given Cait's contract.

Due to her upbringing and time spent in the Combat Zone, Cait is slow to trust and finds it hard to believe anybody would be nice to her without expecting anything in return. Over time she comes to trust the Sole Survivor, telling them about her addiction to Psycho and desire to be cured of it. Her addiction is too strong to be handled by a doctor so she mentions rumors of a cure in Vault 95 and requests the Sole Survivor take her there.

Skills
Cait is proficient at picking locks. In order to pick a lock however she has to have a Bobby pin in her inventory.

Appearances
Cait appears only in Fallout 4.

Bugs

 * Cait's quest might not trigger after her confession about her addiction. If you take another companion and send her back to a settlement, then talk with her the quest should trigger. (It may have to do with her being flagged as a companion)
 * If needing to raise Cait's affection, one can do so by exploiting a terminal that controls a safe. The player character can unlock the safe, which will boost Cait's affection, lock the safe again via the terminal, quicksave, and load. This method will bypass the "refractory period" on Cait's affection and allow them to boost her affection in a relatively short period of time. One such location is Fiddler's Green Trailer Estates, which is along the western edge of the map, south of Sanctuary.
 * At the entrance of Vault 81 Cait can be commanded to open the locked door leading to Curie's room, however the door can only be unlocked from the other side using a terminal. She says she is unable to unlock it, but the door opens.
 * Between Somerville Place and Vault 95 there is a small military building that houses a Legendary Sentry Bot. Ordering Cait to unlock the main door will cause her to walk away from the building or simply stand there. Ordering her to go stand in front of the door and then giving an order to unlock it will cause her to walk away.
 * Cait will talk about wanting to "lower the dosage" if she thinks she is being followed in combat after Vault 95.
 * If you give her Psychos, she will use them during combat.
