Cait

Cait is a companion in Fallout 4.

Background
Cait is an Irish pit-fighter and chem-addict in the Combat Zone. She is able to pick locks up to and including a Master rating, though it can take her a few tries. Despite being quite harsh and wild, Cait can be persuaded to change her outlook on life. Her selfish and harsh attitude can primarily be attributed to her difficult upbringing.

Cait's parents were abusive and distant, eventually selling her into slavery once she turned 18. She spent five years pickpocketing in order to buy her freedom, choosing to track down and murder her parents in lieu of rebuilding her life afterwards. Racked with guilt after the murder she begins using Psycho and finds herself in the Combat Zone, fighting there for three years. After the Sole Survivor defeats the Raiders watching Cait's latest bout, her agent, Tommy, gives her contract (and thus Cait) to the Sole Survivor - passing a speech check reveals that Tommy wants Cait gone because of her carelessness and addiction.

It's revealed through dialogue that Cait is not used to anyone being nice to her without expecting something in return.

Range of interests

 * Cait approves of the player character successfully picking locks
 * Cait approves of alcohol and chem usage until the completion of her personal quest (using either afterwards results in disapproval)
 * Cait approves of sarcasm
 * Cait approves of violence
 * Cait approves of selfish action such as asking for, or trying to increase, rewards
 * Cait disapproves of the player character flirting with other NPCs if she's traveling with you

Maxed approval with Cait grants the Sole Survivor the Trigger Rush perk, which increases Action Point regeneration when the player's health is below 25%.
