How Little We Know How Little We Know is a in " " . Detailed walkthrough ( NCR / House / Yes Man ) . Warning : It is tricky to avoid permanently locking options in this quest . It is best taken after completing Bye Bye Love , as completing this quest will render Bye Bye Love either unobtainable or unable to be completed . Also , If you don ' t speak to Liza O ' Malley before starting How Little We Know , then you will not be able to complete For the Republic , Part 2 , see Bugs below . And , completing this quest incorrectly prevents you from acquiring the Pimp - Boy 3 Billion . This quest can be given by at Mick & Ralph ' s after asking him for work . He mentions that the Omertas have stopped buying guns from him without a word as to why . This quest can also be activated after talking to Yes Man . If you are going to do the Wild Card quests , make sure to ask him about the Omertas , so that new speech options progress the quest when exploring Gomorrah . Otherwise , you will have to return to Yes Man and opt to ignore the Omertas , if you ' ve given up finding clues . 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 . You can also automatically receive this quest when you accept The House Always Wins IV from Mr . House . Once the quest starts , you can talk to the receptionist in the main entrance of Gomorrah . If she has a Speech option for you to ask her information about " the outstanding balance " , then she can point you to Cachino , a low level lieutenant . You can ask a few of the dealers / bouncers / hookers for Cachino ' s whereabouts . They will be unfriendly to this and not answer , but Cachino will still turn up after this . Having the Confirmed Bachelor and / or Terrifying Presence perks gives you additional speech options for the same result . Your inquiries will prompt Cachino to approach you when you enter the Brimstone club . Once you meet him , you need to find proof of Cachino ' s work that he ' s been pulling on the side . The Family doesn ' 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 as you enter the bedroom of his suite and another on his person that can be pickpocketed , this is the evidence needed . You can get the key to his suite from the receptionist either by paying 300 , passing a 8 Strength check ( making it free of charge , ) or passing a 55 Barter check which lowers the bribe to 200 caps . ( You can pay her the 300 caps , then pickpocket her to get it back . ) Alternatively , you can just pickpocket Cachino since he is carrying a copy of the journal . Once you confront Cachino with his journal , he will give you 100 caps to get the journal back ; a 60 Barter check makes him give you an additional 200 caps . He tells you about two people in the club who were hired by the bosses as part of their plans and says to talk to Clanden and Troike about specifics . Take the elevator to the suites level to find Clanden . He 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 behind the dresser next to his bed , or you can just pick the safe ' s lock if you have at least 75 Lockpick skill . Inside the safe are the Snuff tapes . You can take the evidence back to Cachino , who will give you the option to confront Clanden with the tapes , or you can just confront Clanden with them . Telling Clanden that you have the tapes gives you the option of telling him to leave and never come back . A 50 Barter check makes him leave after giving you 200 caps . Alternatively , you can can choose to keep the tapes , at which point he will become hostile and attack you . His room key that unlocks the safe also unlocks the door to the 100 Lockpick maintenance room ( on the same suite level to the west . ) Inside is a dead hooker , which you can inspect with 35 Medicine . Troike is found in the lower brimstone level . When talking to him , you can choose a 30 Medicine check , saying that the story he tells you about blacking out doesn ' t make sense . You can find evidence of foul play by looking for the blackmail note in a safe in Big Sal ' s office that proves the bosses set Troike up . If you pick up the note , you CANNOT free Troike from his contract . This makes it impossible to legitimately obtain the Pimp - Boy 3 Billion . Alternatively , you can talk to Big Sal and convince him to free Troike from his contract with a high enough Speech ( 53 ) or Barter ( 45 ) skill . This frees Troike 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 ( giving you bad Karma ) 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 NCR supply shipments and you can discuss destroying the guns . He ' ll give you a key and some thermite to destroy the guns the Omertas have been gathering for their secret plans ; with 70 Speech , you can tell him to plant the thermite himself . The guns are behind a unique door in the hotel , with two footlockers containing a random assortment of s , s , and assault carbine s ( these might help later in the next part of the quest . ) Place the thermite on the 4 crates of weapons and set off the detonator via the now active panel in the hallway near the closest door to the 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 Cachino gives you to kill the bosses , or you could use the holdout weapons you might have 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 80 Speech check to have Big Sal explain the whole plan to you , then you can lie and convince him that Nero wanted him dead . This results in Big Sal killing Nero when combat starts , allowing time for you and Cachino to kill Big Sal . If you want to avoid combat , you can quickly loot the office key from Big Sal and run outside . The various Omerta thug s in the casino will kindly assist you with killing Nero . The quest is complete when the bosses are dead . Cachino takes over the casino , earning you Strip Fame . If you speak to him after the fight , he ' ll give you 50 Gomorrah chip s . Alternative solution . If you inform the guard at the door to the Gomorrah Club that you have proof that one of their guys is dealing on the side , he will let you in to see the bosses . ( Note : You can only do this after you have informed Cachino you have his journal and have decided to keep it . ) You can talk to Big Sal and offer him Cachino ' s journal for 100 or 200 caps if you succeed in a Barter check ( 60 ) . 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 afterward , 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 to make a Chlorine Bomb ; otherwise Clanden will tell you what is needed . Container of chlorine can be stolen from the Ultra - Luxe casino or purchased from in Freeside . The Chlorine from Ultra - Luxe is found in a small supply closet with an Easy lock on it , in the area behind Mortimer ' s counter . You can also persuade Ralph to give you Chlorine for free by passing a Science speech check of 60 . 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 your map , guarded by 3 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 rewards you with 400 caps . You can also speak to him about 50 Gomorrah tokens . Choosing this solution will cause the player to gain infamy with the New Vegas Strip , and during the quest , a dialogue option will appear when talking to Yes Man saying that you support the Omerta ' s plans of attacking and taking over the Strip .
