Bye Bye Love

 is a quest in Fallout: New Vegas.

Quick walkthrough
This is a quest that begins in the Gomorrah Casino. If the Courier goes into the courtyard Joana will begin a conversation. Passing a Medicine or Speech check will initiate dialog that will eventually have Joana talk about Cachino and Carlitos. The Courier has the option to help Joana (for free or otherwise) by finding Carlitos (located in the diner of Vault 21). After some running back and forth between Joana and Carlitos, the Courier can help Joana, Carlitos, and 2 of Joana's girls escape to Freeside. When

Behind the Scenes

 * The name of the quest might be a reference to the "Everly Brothers" song of the same name.
 * The name of the quest may also be a reference to a song by The Cars of the same name.

Bugs
Due to a glitch, Carlitos isn't appearing in the game for many people, making the quest temporarily unfinishable. To fix this, simply go to the diner in the Vault 21 hotel and use the console command: player.placeleveledactoratme 11f862. This will spawn Carlitos right in front of you.

Another glitch has risen as Joana seems to disappear too after you talk with Carlitos. To fix the Joana glitch, go to the Gomorrah courtyard and us the console command: player.placeleveledactoratme 0010c6f6.
 * Another glitch can render this method useless: spawning Joana in the courtyard makes her disappear once she enters her room (since she tells the player to follow her to her room). If you spawn her inside her room, she keeps asking the player to go to her room.
 * This glitch will happen on the PS3 if you complete the How Little We Know quest before taking Joana out of the casino.

Yet another glitch exists where, after telling Joana the escape plan, she arrives in the lobby of Gomorrah - but does not follow the player. Neither do the disguised hookers waiting outside the casino; leaving to Freeside without them results in failing the quest a few hours later.

Sometimes before executing the final part of the mission Joana might be dancing below her room, although the mission icon shows that she is in her room.

After running back and forth a few times, the dialogue option to get Joanna to run away might fail to appear. The only way around this seems to be to have a high enough speech to convince her.

Killing the bosses with Cachino during the quest How Little We Know can cause you to fail this quest.
