Bittercup

 is one of the citizens of Big Town in the year 2277.

Background
It is revealed that through the course of her life she has been involved with all of the men in Big Town. Her first boyfriend was Pappy, who she left upon arriving in Big Town believing he was a liar. She then went on to date every man in town, including Timebomb, who has no recollection of the relationship.

Quests

 * Big Trouble in Big Town: When the player first meets Bittercup, she will tell you that Red had been captured by super mutants and was taken to Germantown Police HQ along with Shorty.

Other interactions
Regardless of your character's gender, if you flirt with Bittercup successfully she will declare you her next love interest.

Effects of player actions
If you become Bittercup's next lover, she'll give you things she finds in the wasteland. You can return to her once every 13 hours for a random present such as squirrel-on-a-stick, purified or dirty water, a stimpak, noodles, blood pack or Nuka-Cola, sometimes even shotgun shells, 5.56 rounds, 10mm rounds, or .308 rounds.

Appearances
Bittercup only appears in Fallout 3.

Bugs

 * You may keep getting ammo 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 PC.
