How Little We Know

 is a quest in Fallout: New Vegas.

Quick walkthrough
In this quest you can choose whether to help Cachino end the reign of the Omertas... or not.

NOTE: Helping Cachino will reveal the full extent of the plans (Speech check of 80), while helping the Omerta bosses will not.

Detailed walkthrough
This quest is activated after talking to Yes Man, once Bye Bye Love is complete, or started after a few tasks during For the Republic, Part 2. Inside the main entrance to the Gomorrah, talk to receptionist on your left. If it appears as a Speech option, ask her about "the outstanding balance" on information to find out what's been going on in Gomorrah. She will tell you to find Cachino, a low level lieutenant, and ask him about suspicious Omerta activities. If there is no "outstanding balance" speech option with the receptionist, ask a few of the dealers/bouncers/hookers about where you can find Cachino. They will all tell you to go away, but eventually Cachino will appear on the casino floor and talk to you. If you have the Terrifying Presence perk, you get a new speech option and they'll tell you to meet him in Brimestone. During For the Republic, Part 2, you will be asked to get some information regarding the Omertas by Colonel Moore. She will then tell the Courier to talk to Liza O'Malley to start this quest. The quest can also be given by Mick (Fallout: New Vegas) at Mick and Ralphs after asking him for work. He mentions that the Omertas have stopped buying guns from him without a word as to why.

Once the quest starts, you need to find proof of Cachino's work he's been pulling on the side. The Omertas don't know about this because it goes against Omerta rules, putting his life at risk if it ever gets out. There is a journal in his desk directly to the left in the bedroom of his suite and another on his person that can be pick pocketed, this is the evidence needed. You can get the key to his suite from the receptionist for 300 caps, passing a Strength check of 8 (making it free of charge) or a Barter skill check of 55 (lowering the bribe to 200 caps). Once you return to Cachino and tell him you have his journal, he will offer you 100 caps to get the journal back, or if you have Barter of 60, get an additional 200 caps for his "friendship." He tells you about two people in the club that were brought in by the bosses as part of their plans and says to talk to Clanden and Troike about specifics.

Clanden will not give you any clues or talk with you about what he does at all, even if you mention that Cachino sent you. If you go back and speak to Cachino, he'll mention he did some asking around and the bosses plans would be screwed if Clanden wasn't around, so he asks you to kill Clanden discreetly. Alternatively, you can steal Clanden's key off him which opens a safe located in his room behind the wardrobe next to the bed. Taking the evidence within back to Cachino will result in him telling you to confront Clanden with the tapes and blackmail him into either leaving Vegas or helping you. The key gained from pickpocketing Clanden can also be used to open one of the maintenance rooms on the suite level, where a dead hooker can be found (which you can investigate), and proves Clanden's shady dealings.


 * NOTE: Confronting Clanden can result in him becoming hostile and attacking.
 * NOTE: Clanden will turn hostile as soon as he sees you draw a gun.
 * NOTE: Killing Clanden before you are instructed to will result in failure of the quest but the player still receives the same rewards (positive karma, experience, etc.). Same goes for Cachino.

When you speak to Troike, start asking about the dead hooker. If you have a high enough Medicine skill you can say that the story he tells you about blacking out doesn't add up. The player can find evidence that there was foul play by looking for the blackmail note in Big Sal's office safe that proves the bosses set Troike up. Alternatively, you can talk to Big Sal and convince him to free Troike from his contract with a high enough Speech or Barter skill, this allows Troike to be freed without having to investigate the dead hooker incident or find any evidence. If you have a Speech skill of 80, you can lie to Troike and mention to him you'll tell the NCR of his dealing, bypassing the hooker investigation and talking to Big Sal.

Once Troike has been freed of his contract, he will cooperate and tell you about his involvement with the Omertas. He'll tell you he was smuggling guns in through NCR supply shipments, and you can discuss destroying the guns. He'll give you some Thermite and a key to destroy the guns the Omertas have been gathering for their secret plans, or if your speech is high enough you can convince him to plant the Thermite himself. The guns are behind a unique door in the hotel, look for two Flamer's, a Sniper Rifle, and two Marksman Carbine's (these will help later in the next part of the quest). Place the Thermite on the guns and set off the detonator via the panel near the closest door of room. If Troike plants the Thermite himself, he'll get caught and rat you out before the Omertas kill him, but this won't ruin any of your objectives.

After you speak to Cachino upon completion of both objectives, he'll tell you Big Sal and Nero need to be killed now. Luckily, they just put him in charge of finding out who's responsible for ruining their plans, and he'll lead you to a small room where the two bosses are. It is possible to convince Cachino to wait for your initiation signal with a Speech of 80 before the assassination. If you didn't get the guns from the room before you used the Thermite, you can use the Sawed-off shotgun Cachino gives you to kill the bosses, or you could use the holdout weapons you smuggled into the casino. Upon entering the room, the bosses will ask you to have a seat, and a conversation will begin. They talk about how they know you've been ruining their plans and how they want to kill you. At any point in the conversation you can start combat through a dialogue option, but it is possible with a Speech check of 80 to have Big Sal explain the whole plan to you and convince him that Nero was helping you. This results in Big Sal shooting Nero when combat starts. However, if you do this, Big Sal and Cachino will likely die very fast. If you want to avoid combat, you can quickly loot the office key from Big Sal and run outside. The various Omerta Thugs in the casino will kindly assist you with killing Nero.

Once the bosses are dead, the quest is complete and Cachino will take over the casino. If you speak to him after the fight he'll offer you 50 Gomorrah tokens as thanks.

Alternative Solution
If you inform the guard at the door to the Zoara Club that you have proof that one of their guys is dealing on the side, he will let you in to see the bosses. You can talk to Big Sal and offer him Cachino's Journal for 100 or 200 caps if you succeed in a Speech check. After that, everyone is brought into Big Sal's office for a meeting where Button Man will kill Cachino after he begs for his life. Talk to Big Sal afterwards, he'll ask you to take over for Cachino then offer you a job aiding Clanden and Troike in their plans.

For Clanden, it means helping him kill "a large amount of people in a short amount of time". If you have a high enough Science skill (60), you can persuade Clanden into making a Chlorine Bomb easily, otherwise Clanden will tell you what is needed. Chlorine can be stolen from the Ultra-Luxe casino, or purchased from Ralph in Freeside.

Troike will tell you that he is a gun smuggler and inform you that he needs someone to retrieve a crate of guns stolen by the Fiends. The location will be marked on you map, guarded by 4 Fiends. Once you retrieve the Disassembled Weapons Shipment, return to Troike.

Once the Chlorine is given to Clanden and the weapons to Troike, you will then be told to see Big Sal. Upon informing Big Sal of having fulfilled his request to aid Clanden and Troike, he awards you with 400 caps. You can also speak to him about gambling for 50 tokens.

Bugs
When speaking to Cachino before going to kill the bosses, selecting the "Wait" and "Ready" dialogue options may prevent Cachino from further interacting with the player. When trying to re-initiate dialogue, Cachino will only respond that 'there is no time to talk' meaning the player cannot tell him they are ready to go; and he will also remain in place and not lead the player to the meeting with the bosses preventing further progress in the quest including completion. Leaving Cachino there and attempting to finish to quest later will revert Cachino to previous lines of dialogue in which you can only ask about the bosses' plans, Troike, and Clanden. To note, this quest was undertaken before initiating or completing Bye Bye Love as the walkthrough indicates is necessary. It is unknown if this is related to the glitch. (Update, 360): Completing Bye Bye Love does not unlock communication with Cachino. ** This bug can be bypassed, by simply finding the small office where the meeting would take place (next to Big Sal's office on the main floor) and killing the bosses, resulting in a quest complete message, regardless of Cachino following you there. **

When Cachino is supposed to give you the double-barreled shotgun, it may end up in your companions inventory instead of yours. This can occur even if Cachino is still bugged as previously mentioned.

Sometimes, after unlocking the Very Hard locked door in which the Dead prostitute is located, she will get off the table as if sleeping. She will then use the default prostitute dialogue. Not quest-breaking as the dialogue concerning the prostitute occurs with Troike where there are other options for getting him to cooperate.

If you steal Sal and Nero's ammo before sitting down for your chat, choosing the lie option implicating Nero will cause the two of them to stare at one another with guns out, but they will not attack due to lack of ammo.

If you accidentally start a fight with the body guards or security, then leave the Casino to The Strip, when you re-enter the casino the game freezes; your character is unable to move just look around.

The dead prostitute you can inspect during the How Little We Know quest can be found alive and standing after the quest is complete. If you examine her the box telling you to inspect her will still pop up.

If you find and inspect the dead prostitute before the quest, she may be found alive during the quest. She can still be inspected, so the bug does not affect the quest.

After completing this quest Joann will disappear from Gommorah this may be because without the Omertas around she is able to escape or because Cachino was able to keep her for himself.

If you receive the key from the receptionist, you can lift the book off Cachino AND head up to his room to get another copy of his journal. Sell the first one with the Barter check then talk to him again for the 100 caps and intel on the Family's activities option.

If you were previously banned from gambling at Gomorrah, you will still receive chips as a reward, even though you remain banned.

After receiving the option from Cachino to kill Clandon - occasionally killing Clandon will result in a failed mission. In this play through, Troike set off the thermite and didn't know he was exonerated... unknown if this triggered the bug.

After completing the mission, without going into Clandens room with the dead hookers body, going into Clandens room via his room key, the hooker may be alive. You cannot interact with her but only examine her body, which is glitched because she is not dead.
