Apathetic, self-involved, and rebellious, Bittercup is one the of troubled young characters that live in Big Town. She spends time worrying about what dark clothing to wear and applying home made makeup often at the expense of better guarding the town against attack. Many of the other residents of Big Town seem fed up with her, but there is little they can do about it, with the threat of super mutant and raider attacks being a more pressing concern.
Through dialogue, it is revealed that Bittercup has been involved with most of the males in Big Town at one point or another but it is remarkable she does not seem to take any of their interests in a physical way. She had a romantic interest in Pappy, whom she left after arriving in Big Town, believing that he was a liar. She then got with Flash, who snapped after a short time after he couldn't stand her teasing. She claims she then had a relationship with Timebomb; however, he claims he doesn't remember this, since an injury put him in a coma.
More than any other personality trait it should be recognized Bittercup is a frightened young lady who sees death nearly every day and she clings to anyone who takes time to visit with her.
It is revealed through dialogue that Bittercup wears chalk from the Wasteland on her face as makeup.
If the Lone Wanderer is friendly to her, Bittercup will offer miscellaneous items if she is visited just before midnight.
If Bittercup had been particularly fond of the Lone Wanderer but they later enslave Red, Bittercup will at least temporarily stop rewarding them for their late-night visits and the dialogue will revert to what it was before. However, it seems she can overlook your slaver tendencies if you have good Karma.
