Cait

Cait is a possible companion in Fallout 4. She is a chem-addicted Irish pitfighter and can be found 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.

Background
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. She begins using Psycho after the murder and finds herself in the Combat Zone, fighting there for three years until she joins the Sole Survivor.

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 her desire to be cured of it. Her addiction too strong to be handled by a Wasteland doctor, she mentions Vault 95 and requests the Sole Survivor take her there.
