Betsy is part of the 1st Recon. She is in charge of training 10 of Spades and getting him some experience within the 1st Recon. Betsy and 10 of Spades were out doing recon and tracking down Cook-Cook. However, Cook-Cook got the jump on them, knocking out 10 of Spades and raping Betsy before attempting to cook her alive. When the Courier arrives at Camp McCarran, she is in denial over the incident, which begins affecting her performance and relations with her comrades.
Betsy will flirt with a female Courier if her Charisma is 7 or greater. Possessing the Cherchez La Femme perk will allow the Courier to acknowledge her advances, though ultimately, there is no option to actually follow through with it.
