Apathetic, self-involved, and rebellious, Bittercup is one of the troubled young characters that live in Big Town. She spends time worrying about what dark clothing to wear and applying homemade 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 romantically involved with most of the males in Big Town at one point or another, but it is remarkable that 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 involved with Flash, who snapped a short time afterward because 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.
Bittercup Runneth Over: If one endears themselves to Bittercup through dialogue options, she'll give you things she finds in the wasteland. You can return to her once every 24 hours for a random present for a lengthy, albeit limited time.
It is revealed through dialogue that Bittercup wears chalk from the wasteland on her face as makeup.
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 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.
Should the other residents of Big Town somehow die before starting the quest Big Trouble in Big Town she will become depressed. Questioned about the super mutants or if spoken to her next time, she states she wishes to die.
"I was dating Pappy then, you know. I got here and he was all like "Bigtown will be safe", but it wasn't! This place is always under attack! But I don't date liars, so I dumped his ass and got with Flash. But that didn't last very long. Me and Timebomb were a thing for a while, too."
