Detailed walkthrough

Silus is held captive in Camp McCarran, and the NCR is attempting to interrogate him. He will not give information to the NCR, and interrogator Carrie Boyd is looking for help. She informs the player that the NCR does not allow torture of prisoners. The player can suggest a truth serum, beating the prisoner, or calling him names.

If the player has a reputation of Accepted or higher with the NCR, Lieutenant Boyd will allow the player to go in and speak with the centurion. The player will go in unarmed, unless the player's Sneak skill is high enough to bring in holdout weapons.

The Courier can either break Silus or help Silus escape.

Break Silus

The Courier can speak with Silus or attack him outright.

  • Should the player speak with Silus:
    • The direct option is to attack Silus. After a brief fight, Lt. Boyd will come in again and ask Silus if he wants more. When the centurion refuses, the player will briefly speak to him again, and begin attacking once more. After a second round of fighting, Silus will talk.
    • Passing a series of Speech checks with high Speech (50 is enough, though the required Speech skill is not shown) will cause him to spill information.
      • This is worth 50 extra XP
    • With Intelligence 8 or higher, the player can persuade him into thinking that you are working with the Legion and are here to assassinate him; this will result in him telling you all of his plans and give you little information about Caesar's illness. Here, some knowledge of Latin will help you understand the dialogue choices:
      • Timeo Danaos et dona ferentes means "I fear the Greeks, even when they offer gifts." This is a line from the Roman poet Virgil, recounting the doubts of Laocoön, one of the Trojans, about accepting the gift of the Trojan Horse.
      • Corruptio optimi pessima means "Corruption of the best is the worst possibility." It is originally from Pope Gregory I (Gregory the Great).
      • Legum servi sumus means "We are all slaves to the law." The phrase is originally from the Roman orator and statesman Cicero, and in full reads Legum servi sumus ut liberi esse possimus -- "We are the slaves of the law, in order that we might be free."
      • At the end of the conversation the player can attack him, asking if he has any last words, to which he replies "Cedo Nulli" which means "I yield to no one," though he does not become hostile.

You can also kill Silus to gain history points with Boone. Just take Boone with you and give him a weapon like a knife. Enter the room, go through the Speech checks, exit the room and talk to Boyd to get your reward. Take the weapon from Boone and kill Silus. Talk to Boone to advance your history with him and give him back the weapon and leave.

Killing Silus during the interrogation results in Boyd condemning your action by complaining that she lost her best shot at getting a promotion since he didn't reveal anything about the Legion and you ended his suffering, and finishing this diatribe by calling you an "asshole." An NCR Infamy gain is received.

After the information is gained from Silus, you can no longer interact with him, and Lieutenant Boyd will pay you for your troubles.

Help Silus escape

If the player has already been invited to Caesar's camp at The Fort or has a positive reputation with the Legion, they have the option to tell Silus this. The player can choose to stage a fight with him and retrieve his silenced .22 pistol from the locker in the next room. When the player returns for the second round of interrogation, Boyd will confiscate all weapons except the pistol. After giving Silus the weapon, he will fake being unconscious. Boyd will come back in and say it looks like he is "all tuckered out," and she and the player will leave. On the way out, she will tell the corporal to go clean Silus up and he will go in and tell Silus to get up. Silus will kill the Corporal and dress in his clothes. He will then sneak out undetected by the NCR. The Courier will not lose any reputation with the NCR as a result.

Notes

  • After Silus is dressed as an NCR corporal he will not speak to the Courier while he leaves.
  • If Boone is with the Courier, he detects and becomes hostile to Silus once Boyd has left the room and called for the Corporal. Silus also detects Boone and walks around with the pistol drawn. Silus ultimately leaves the room (and will typically be shot dead by Boone) without having shot the Corporal or disguised himself. Boone does not talk about the incident afterwards.
  • The Courier is unable to explain to Silus that they are from the Legion if they are wearing NCR faction armor.

Rewards

  • NCR fame
  • 175 (attacking Silus) or 300 caps (persuading Silus)
  • 325 XP

Notes

  • Although Silus will become hostile to the Courier, he will never actually fight back against their assaults. He will only block and sidestep when they hit him. This means the Courier needs not worry about their Hit Points or Unarmed skill.
  • Caesar approves of the Courier releasing Silus before he could talk about Legion movements, though is less pleased by Silus' capture by NCR troops and plans to punish him.
  • It is not necessary to kill Silus during the interrogation to gain "fame" with Boone. So long as the Courier has Boone as a follower, they can kill Silus before, during, or after the interrogation.
  • Regardless whether the player character chooses to kill Silus during or after the interrogation, all further conversation with Boyd will begin with "Haven't you done enough?" However, this doesn't have an effect on any other dialogue chains - including quest related dialogue.
  • Silus disappears from Camp McCarran once he reaches the terminal doors.
  • If the Courier kills Silus at McCarran, Caesar applauds them, saying that it's good he died before he could talk.
  • If the player approaches Lt. Boyd dressed as a member of the NCR, she will address them as a NCR soldier. The dialogue for this side quest changes and she will disregard the player's offer to help. (Easily fixed by merely taking off the armor and talking to her again).
  • After everything is done, Silus and Boyd will still continue their banter while she is walking away. They will talk to each other as if they are still in the same room despite Boyd being halfway across the building.
  • On PC, if, for any reason, the Courier is unable to initiate the quest through dialogue with Boyd (or simply wishes to bypass the reputation check), the door can be unlocked via console commands, which will force the quest to proceed as normal and can be finished for either faction.

Behind the scenes

The name of this quest is a play on the term "silent treatment," which means to deliberately ignore someone for a period of time, usually because of something they have done.

Bugs

  • Playstation 3Playstation 3Playstation 3 It is possible to earn infinite XP with a glitch while talking to Silus. Use the first speech check option (50 XP), then use intelligence one. After Silus' answer, the speech check will still be available, as well as the the XP. [verified]
  • Xbox 360Xbox 360 If the player leaves the room after the first time Silus is talked to, the room will become inaccessible and further interaction with Lt. Boyd only result in her saying "Let's talk after we finish this up," ending the conversation abruptly. However, it is possible to return to the area in a few game hours. [verified]
  • Xbox 360Xbox 360 The door has many opportunities to bug: if the game is saved after Boyd enters the room to introduce the Courier, the room will remain locked prohibiting the interrogation after she leaves. Also, if Silus is murdered in order to earn points with Boone towards triggering his character quest I Forgot to Remember to Forget, Boyd may become stuck in the room afterwards, preventing the player from talking to her again and completing I Put a Spell on You. [verified]
  • Playstation 3Playstation 3Playstation 3 Reloading the auto save that occurs when first entering the room may cause all of the player's weapons to spawn back in the inventory. [verified]
  • PCPC Around the third going into the interrogation room, a random NCR trooper can spawn inside as well, kiling Silus, preventing the full reward and resulting in infamy with the NCR. [verified]
  • Playstation 3Playstation 3Playstation 3 sometimes Boyd's face may not load and will only have her eyes and mouth showing. It can be fixed by exiting the building and re-entering. [verified]
  • PCPC Do the speech option of [Intelligence] and don't leave the room. If you engage in conversation with Silius while Boyd is talking to him again, Boyd may disappear, although the conversation between her and Silus continues. If you tell Silus you are not from Caesar's Legion while this happens, after Boyd finishes the speech you can talk to Silus again and apparently he just forgot what you said and thinks again that you are a legionary. [verified]
  • Xbox 360Xbox 360 If you initiate this quest and have Boyd enter and talk to Silus but then you don't go in after she exits and you leave and proceed to do various other quests and gain rep with the NCR, when you come back you may be unable to continue the quest and Boyd will act as if you "have to do a lot more NCR ass-kissing" before she'll let you help with Silus. If you talk to Hsu, he will still recommend that you see if Boyd needs help. [verified]
  • Xbox 360Xbox 360 After entering the interrogation room for a second time and beating Silus to get the information a glitch can occur when exiting the room to talk to Boyd. She will disappear and not be anywhere within the building. [verified]
    • Note: After experiencing this, it may be possible to find her through the I Put a Spell on You quest. She may appear in the hall to the right of where you find Col. Hsu, by the Nuka Cola machine. This may require I Put a Spell on You not being started until after Boyd disappears.
  • PCPC After helping Silus escape, sometimes Lt. Boyd got stuck in the same dialog, making future interactions with her impossible. On the PC, this can be fixed in console with the command set "00E7913".bSilusUnconscious to 0. [verified]
  • Playstation 3Playstation 3Playstation 3 Loading the Autosave when you enter the interrogation room may result in you being permanently locked inside with Silus. [verified]
    • Note: This can be worked around by immediately exiting the room, before talking to Silus. The player then can reenter the room and proceed as normal.
  • Playstation 3Playstation 3Playstation 3 If you do all of the speech checks in Silus' dialogue then kill him before Boyd tells you to stop, Boyd returns to the room and lock it and will not leave but appear to be talking to the empty chair. [verified]
  • Xbox 360Xbox 360 If you have ED-E or Boone as a companion, he can follow you into the interrogation room. Once you start hitting Silus, turning him hostile for brief periods, ED-E will also attack him. [verified]
  • Xbox 360Xbox 360 After entering the interrogation room for the first time, re-load the auto save of when you entered the room. You should now have all your weapons not just holdouts. [verified]
  • Xbox 360Xbox 360 Silus must reach the terminal doors without being made hostile through a failed pickpocket attempt (even if he doesn't detect the player) in order for Caesar to acknowledge his release. [verified]
  • Xbox 360Xbox 360 When interogating Silus, any characters inside the terminal, most commonly the Corporal or your followers, may believe that Silus is an actual threat and come to your aid, resulting in Silus' death. [verified]
  • Playstation 3Playstation 3Playstation 3 Sometimes when Boyd enters the room where Silus is located, she may not exit the room making the quest impossible to complete, this may be fixed by continuing other quests. [verified]
  • PCPC There's a chance that after beating Silus the first time and going back in that he won't respond to anything; trying to talk to him fails, and he merely sits in the chair. At this point, killing him will yield no angry dialogue with Boyd, nor any NCR infamy. Also, if the room is left, it cannot be entered again, leaving the quest broken. [verified]
