Joana

 is a prostitute living in the Gomorrah Casino in 2281.

Background
Joana is a prostitute who can be found dancing in the Courtyard of Gomorrah or in her room just off the second floor of the courtyard. The Courier may have sex with her for free after two speech checks (50 & 75) or with the Lady Killer or Cherchez La Femme perks, otherwise the price is 100 caps. However she will not have sex with the player if you have activated the Bye Bye Love quest.

She is a Med-X addict, using it to deal with the loss of her lover Carlitos and sexual abuse by the Omertas lieutenant Cachino.

Quests

 * Bye Bye Love: In one of the endings of the quest, she will become the girlfriend of her long lost lover Carlitos.
 * How Little We Know: If she survives Bye Bye Love, she will inform you that there is something going on in the Gomorrah, and start the quest How Little We Know; provided you are not involved in this quest already.

Other interactions
With a high enough Medicine score (50) you can call her out on her addiction and initiate her quest, Bye Bye Love. Alternatively, if you wait one or two more dialogue choices, an option to do another speech check, score (75), and you can ask her what her problem is and she will give you her quest if you continue the dialogue.

Appearances
appears in Fallout: New Vegas.

Bugs
Prid 00112471
 * As with Red Lucy, Joana may not have sex with the player after the first time, she will only talk to the player and lay down again. This can be fixed by sleeping in her bed for 12 or 24 hours.
 * If you pass the speech check of 75 and do not enter her room, it can be repeated indefinitely for 83 exp with each attempt.
 * If you have sex with her, after you wake up she will occasionally be where she was before the sex, this is brief, however, as she then teleports back into the bed.
 * If you talk to her while she's in bed, she will wake up and the clothes she is wearing will change
 * After having sex with her, the PC will most likely have their health restored and their limbs fully healed, even when hardcore mode is activated.
 * Entering the courtyard and leaving before she initiates contact will cause her to chase the courier across the world. She has shown up at Alpha, Delta, Foxtrot, Hidden Valley, Primm, Mojave Outpost, Mole Rat Farm, and Camp Searchlight.
 * If you use Prid 112471 enable move to player after the completing Bye Bye Love, she will appear as she did at the end of the quest and say "I'm so happy to see you! Me and Carlitos have been living here since I escaped." It is unknown whether this is a bug, or a programming fault, because she seemingly disappears after Bye Bye Love.
 * Joana will disappear if you complete "How Little We Know" before "Bye Bye Love," even with the 1.3 patch. To fix this bug, enter the following commands in the console:

Resurrect

Enable
 * After killing Joana, only her Sexy Sleepwear is removable, not her exposed Prostitute outfit
 * Joana should now stand in front of you as nothing has ever happened
