Detailed walkthrough

Persuading Cass

Upon first interaction with Cass, she will direct the Courier to the Crimson Caravan Company for work. Once there, Alice McLafferty, the company's manager, will assign a series of jobs. One of these jobs will involve buying off Cass's caravan, Cassidy Caravans. There are several methods of convincing her to give up her caravan:

  • With a Barter skill of 50, one can choose to sweeten the deal by throwing in an extra 750 caps.
  • With a Barter skill of 75, one can challenge her to a drinking contest. One will need to acquire twelve bottles of whiskey. (The dialogue will vary depending on one's Endurance and alcohol addiction status, but the outcome is always the same: she will agree to sell.)
  • With a Speech skill of 50, one can suggest that the outpost is a pretty terrible place to be trapped.
    • Cass will agree, but Ranger Jackson won't allow her to leave. The Courier can earn Jackson's agreement by performing the job he assigns.
  • With a Speech skill of 75, one can persuade her by telling her that she's responsible for the destruction of her caravan.


  • There is a bug with There Stands the Grass that can lock up Thomas Hildern's dialogue preventing the completion of You Can Depend on Me and ultimately preventing the recruitment of Rose of Sharon Cassidy as a companion. Therefore it is highly recommended that the player complete this quest prior to There Stands the Grass.
  • These are the only possible methods of persuading her.
  • It is possible to get twice as much experience with multiple skill checks. For the first check, challenge Cass to a drinking competition and then instead of getting whiskey, choose one of the other options for the second check.

The Mystery of the Caravans

After Cass is persuaded, she can be recruited as a companion. If one has Evil Karma, she will not initiate the quest and will instead yell or even leave the party.

After talking to her (via the companion wheel) with sufficient Karma for her not to be annoyed, she will want to visit her caravan's wreckage site to pay her respects. Cass's caravan wreckage will have nothing left but a dead pack brahmin and some miscellaneous loot. Upon further examination, Cass will notice something suspicious and suggests visiting Griffin Wares' caravan.

The second caravan, which is found nearby a billboard south-west of the Horowitz farmstead has suffered the same fate as her caravan. Aside from the three dead pack brahmins and various scattered loot, there are three ash piles. Cass will become even more suspicious, and will want to examine Durable Dunn's caravan.

Durable Dunn's caravan, aside from the similar damage the earlier caravans sustained, has the corpses of a Van Graff thug and a Crimson Caravan guard. The picture will be clear to Cass; the Crimson Caravan Company and Silver Rush are colluding to eliminate competition for the caravan business. She wishes to kill Alice McLafferty, the Crimson Caravan manager, and Gloria Van Graff, the head merchant of the Silver Rush, for all of the damage they caused. One can intervene in Cass's rash decisions and offer a more peaceful solution, or agree and aid her in killing both of them. Attention: If this is done after the player has started Birds of a Feather with the Silver Rush faction, be aware there is a Silver Rush member near by. Killing him will cause the Silver Rush faction to be hostile towards the player upon returning to Freeside. When Simon begins to attack the player, the Birds of a Feather quest is failed.

Peaceful solution

To come up with a more peaceful solution, one must gather evidence of the two caravans' true motives. These pieces of evidence are located in the two following locations: a safe in the Crimson Caravan main office and a safe behind a locked room in the Silver Rush. If one agreed to help Cass "settle accounts" with Alice McLafferty and Van Graffs, there won't be any evidence in the safes if changing one's mind.

Crimson Caravan main office

The evidence required to prove Crimson Caravan's reasons for attacking is located in a safe in the main office, next to Alice McLafferty's desk. It can be unlocked in two possible ways, with a loss of karma:

  • Having a Lockpick skill of 50.
  • Unlocking the safe with McLafferty's safe key. It can be acquired by pickpocketing her.

Once the incriminating note has been obtained, talk to Cass and show her the evidence.

Silver Rush

The evidence required to prove the Van Graffs' true motives is located in a safe behind a locked door inside the store. There are two ways to open the door:

  • Unlocking it with a Lockpick skill of 75.
  • Using a key to unlock it, which is carried by all of the Van Graff members (except for the crier).

The safe can also be opened in two ways:

  • Unlocking it with a Lockpick skill of 75.
  • Disengaging the lock by hacking the terminal near it with a Science skill of 75.

Again, once the evidence has been obtained, talk to Cass and show her the evidence.

Cass's Calm Heart

Once the two pieces of evidence have been obtained, Cass will suggest taking it to Ranger Jackson. The evidence will be passed on to NCR higher-ups, determining the fate of the two companies.

The quest will end once one talks to Cass. Cass will receive the Calm Heart perk, which grants her an additional 50 HP. One will also receive 500 Experience Points.

Additional notes

  • Obtaining the evidence inside the Crimson Caravan main office will be easier at night, since the office will be empty. Alice will also be sleeping, making the key easier to pickpocket.
  • Jean-Baptiste Cutting, Silver Rush's second-in-command, can turn hostile after a period of time if he is in the same room as Cass.
  • Even if spotted lockpicking the door inside the Silver Rush, the Van Graffs won't become hostile, unless playing the Ultimate Edition.
  • As of patch 1.2, turning in the evidence will turn the Van Graffs permanently hostile.
  • Lockpicking all of the required safes and doors will incur negative Karma.

Violent solution

One can aid Cass's initial plan by helping her kill Alice McLafferty and Gloria Van Graff, by any means necessary. So long as both of the managers are dead, Cass will have fulfilled her vengeance.

  • There is a possible glitch to this. if one first kills the Van Graffs and have previously talked to Cass (one may also have to buy Cassidy Caravans for the You Can Depend On Me quest too), it automatically starts the Violent Solution. When one next talks to her she will want to kill Alice McLafferty next, entirely skipping the parts where one must search the destroyed caravans.
  • Another glitch involves killing Alice McLafferty with a silenced weapon to avoid the penalties to reputation or allowing a companion to get the finishing blow for the same reason. It is also possible to kill Alice and have the quest complete in these ways if Cass is present. Talking to Cass after killing Alice even though the quest did not update will finish the quest violently.

Cass's Hand of Vengeance

Once both targets are dead, speak to Cass to conclude the quest. Cass will earn the Hand of Vengeance perk, which gives her an additional 15% damage with guns. One will also receive 500 experience points.

Quest stages

5 Cass is drowning her sorrows at the Mojave Outpost. Her advice? Go work for the Crimson Caravan.
6 Pitch in at the Crimson Caravan company if you're looking for caravan work.
7 Return to Cass and see if you can get her to part with the title for Cassidy Caravans.
8 Clear the roads for Jackson in Mojave Outpost HQ to allow Cass freedom to leave.
9 (Optional) "Remove" Jackson as an obstacle without Cass or anyone the wiser.
10 Pay your respects with Cass at her caravan's grave.
20 Investigate the wreckage of the Griffin Wares caravan with Cass.
30 Track down Durable Dunn's missing caravan with Cass.
40 Investigate the Crimson Caravan for reasons behind the attack.
50 Investigate the Silver Rush in Freeside for evidence on the Van Graffs' guilt.
60 Take the evidence of the Caravan attacks to Jackson at the Mojave Outpost.
70Quest finishedEvidence passed to NCR.
80 Find Alice McLafferty at the Crimson Caravan Camp and "settle accounts."
90 Find Gloria Van Graff at the Silver Rush in Freeside and make that bitch eat her hair.
100Quest finishedAccounts settled.


  • It is possible to finish the quest peacefully, then kill both of the targets. Cass will end up with both of the perks. (Note that the GECK scripts appear to take away the Calm Heart perk when the Hand of Vengeance perk is granted, but it appears that companion perks are handled specially - in-game testing shows that she keeps both perks.)
  • If you kill anyone of either faction after completing this quest the peaceful way, Cass will ask you why you did not keep it simple and kill them in the first place.
  • It is possible to finish the quest by killing Cass and returning to the Van Graffs. However, if you're not hidden or use a stealth-based way of doing so, you will incur a negative reputation with the NCR.
  • If Ranger Jackson is dead when the player suggests finishing this quest peacefully by gathering evidence, Cass will decline and the player will have to do it the "old fashioned way".
  • At the end of the peaceful solution, Ranger Jackson warns the player not to kill McLafferty or Van Graff, or he'll "put you in chains." If the player then kills both or either characters and returns to the Mojave Outpost, speaking to Jackson does not trigger any negative consequences.
  • It's not possible to complete this quest and Birds of a Feather quest at the same playthrough in the console version since Cass will be killed.
  • Killing Gloria Van Graff or Jean-Baptiste Cutting will fail the quest Birds of a Feather.
  • Killing Alice McLafferty will fail the quest Pressing Matters (but it's completely possible to complete that quest before killing her in Heartache by the Number).
  • It is possible to kill the Van Graffs first by presenting Cass to them as requested, then objecting when they try to kill her. This method will still allow one to turn in the evidence from Alice McLafferty to Ranger Jackson, and complete the peaceful option.
  • If one has already killed Gloria and the Van Graff family, after going into the Silver Rush with Cass and getting the evidence from the safe, when talking to her and trying to show her the evidence, she will go on about doing it the old fashioned way, and the marker will lead one to Alice to kill her. If one ignores that and still report to Ranger Jackson, he will accept the evidence, and will complete the quest peacefully, gaining the Calm Heart perk. The ranger will also lead to the quest Can You Find it in Your Heart?
  • If working towards the peaceful solution and then either change one's mind or alienate the NCR (which makes the peaceful solution unreachable), one can switch to the violent solution simply by killing either Gloria Van Graff or Alice McLafferty. One cannot make this switch through dialogue; just kill the targets to make the switch. Cass will ask to let her know next time the Courier wants to change their mind.
  • If one accepted Heartache by the Number but has not picked up Cass as a companion, and one talks to her after having killed Gloria for unrelated reasons, it will trigger the final phase of the quest, she will rejoice over Van Graff's death out of the blue and propose to go settle the score with Alice McLafferty.
