Apathetic, self-involved, and rebellious, Bittercup is the lone exception to Big Town’s desperate, overwhelmed atmosphere. She has completely retreated into a one-woman subculture of her own making, spending time applying makeup and wearing dark clothing instead of guarding the town against attack. The other residents of Big Town are fed up with her, but there is little they can do about it, with the threat of Mutant and Raider attacks being a more pressing concern.[1]
She has been involved with all of the men in Big Town at one point or another. She had a romantic interest in Pappy, whom she left after arriving in Big Town, believing that he was a liar. She will give the player a random selection of items if you visit her in Big Town. On rare occasions, this item may be stimpaks.
Regardless of your character's gender, if you flirt with Bittercup successfully, she will declare you her next love interest.
It is revealed through dialogue that Bittercup wears chalk from the Wasteland on her face as makeup.
If you give her a better weapon by reverse-pickpocketing (for example to use when defending Big Town from the super mutants) she will still be using her lead pipe later in the game.
PlayStation 3PCXbox 360 You may keep getting ammunition from her even after saying, "I'm not even going to begin to tell you what's wrong with that question" when asked if you are seeing anyone. This also occurs with the dialogue asking if Bittercup was hitting on the player.
