Sierra Petrovita

Sierra Petrovita is a Nuka-Cola addict (It is not possible for the PC to get addicted to regular Nuka-Cola, although Nuka-Cola Quantum has a 10% chance of addiction) living in Girdershade. Sierra is blissfully and innocently unaware of her neighbor Ronald Laren's obsession with her or his unsavory intentions with her.

She has her own Nuka-Cola "museum," (really just a display of her collection within her shack) which she gives tours in. After completing the tour she will give you an Ice Cold Nuka-Cola. Taking the tour initiates The Nuka-Cola Challenge quest in which the Lone Wanderer must gather 30 Nuka-Cola Quantums for 40 Bottle caps per bottle. Completing the quest her way grants the player good karma.

Should you instead help Ronald Laren in his quest to sleep with Sierra by giving him the Quantums (which he then gives to Sierra), she completely misunderstands his subsequent sexual innuendo and believes he intends to propose marriage to her. The player will receive 40 Bottle caps (but, if you succeed in a speech check you can get 80 Bottle caps) as well as bad karma.

Unmarked quest: Mississippi Quantum Pie
After completing her mission to obtain a large supply of Nuka-Cola Quantum, if you bring her 1 Nuka-Cola Quantum, 1 bag of Flour and 1 bottle of Vodka, she can make you a Mississippi Quantum Pie.

Trivia

 * Just as Nuka-Cola is an obvious parody of Coca-Cola, Sierra is a parody of people who collect Coke memorabilia, in particular the distinctive glass bottles used by the company during the first half of the 20th Century.


 * There are 65 Nuka-Colas in Sierra Petrovita's House (including on top of the Nuka-Cola Machine), 71 if you include the 5 Ice-Cold Nuka Colas in her fridge and the one she gives you at the end of her tour. This is far and away more than the runner-up location, the 19 Nuka-Colas in the jack-knifed truck with Old Olney's Nuka-Cola Quantum delivery.

Bugs

 * If you kill Sierra, even after severing her head from her body, she may still complain when you steal stuff from her house. She really does love her Nuka-Cola.


 * It is not recommended that you have Fawkes with you should you ever enter Sierra's house, as he may attempt to kill her for some reason. Possibly because he is a mutant and poses a threat to her.


 * Sierra may sometimes randomly die after you deliver the Naughty Nightwear to Ronald Laren. (Tested on 360)


 * A Deathclaw can sometimes appear in Sierra's house. (Needs confirmation)


 * Sometimes, Sierra Petrovita will run around her home in "fleeing" mode for a random period of time. In some cases, she won't come out, making it impossible to talk to her. Reloading a save will not always fix this. It appears to happen randomly, but known causes include the player killing an NPC that she likes (Ronald) or having a hostile NPC follow the player into her house. Using a pip-boy while she is fleeing, will cause her to stop fleeing (tested on the xbox 360 version only).


 * Also Sierra may randomly become hostile to you, therefore it might be risky to bring in NPC followers, as they could kill her.
