Sarah grew up in Vault 21. Like her brother, she suffers from agoraphobia and as such, rarely leaves the Vault. After Mr. House took control of the Vault and made known his plans to evict the residents and seal it with concrete, Sarah and her brother convinced him to spare the upper level. By Mr. House's acceptance, Sarah won the ability to remain in her home, now converted into a hotel and gift shop with her as the proprietor. Sarah's brother was allowed to stay nearby, now working out of a warehouse immediately next door to the Vault 21 Hotel. Sarah and her brother seem to keep in touch via e-mail despite their physical proximity, likely due to the extreme discomfort both would experience from being outside even for the short trip between structures.
As vault suits are extremely popular items for the gift shop, Sarah is always on the lookout for extra stock. The player character can help her with this through the unmarked quest Suits You, Sarah.
With a barter check of 65, she will accept Boomer jumpsuits along with Vault jumpsuits. They will not count towards the 30 jumpsuits you need to give her.
If you kill Mr. House, you can mention it to Sarah. She'll be delighted that she now technically owns the Vault, but it otherwise has no effect on her unmarked quest.
Through certain dialogue options and after giving her the 30 jumpsuits, she can be propositioned for sex, at which point she will tell the player she will meet the player in their room. Sarah will have sex with the player regardless of their gender.
If you insult her in any way she will become angry and say she "Doesn't have to take that shit from anyone."
Sarah has a picture of James and Catherine on the wall next to her bedside dresser.
If she is killed she will be replaced by a Securitron. The Securitron, however, won't buy vault suits.
Sarah refuses to rent you a room if you have negative Strip reputation. Strangely, she also refuses if your reputation is at Wild Child. Because of this, it's possible to lock yourself out of renting by raising your positive Strip reputation (going from Soft-Hearted Devil to Wild Child).
Sarah grew up in Vault 21, but oddly doesn't have a Pip-Boy.
When completing a sale with her, her lines when exiting the barter screen are said by a different voice actress.
After having sex with her, she will stay asleep in your bed with her Vault 21 jumpsuit unequipped and will only reequip it after she wakes up. This means, if you pick her pocket, you can take the Vault 21 jumpsuit and she will remain in her underwear indefinitely. This leaves the option to dress her however you please, for she will equip any clothing item in her inventory.
Sarah is essential to Classic Inspiration; her death will make it impossible for the player to complete that quest, due to her brother becoming despondent at her demise.

pcps3xbox360 After having sex with her and waking her up, she will have a different voice than normal. This also occurs when she greets the player in passing (without engaging in dialogue). This glitch may also occur at the end of a transaction. [verified]
pcps3xbox360 It is possible for her to not recognize that you have Vault 21 or Vault 19 suits in your inventory to give to her. The same problem can occur with any type of Vault suit if you are withdrawing them one at a time from a companion's inventory, but these issues can be fixed by exiting and re-entering the gift shop.

pcxbox360 If you play a character with speech abilities high enough to use all the dialogue options (and you do it when you meet her for the first time), you possibly won't be able to have sex with her whether you have delivered any quantity of suits or not. She may sound as if she's going to meet you in the room right away, but she will actually stay in the shop. [verified]
