Help Cass Deal with the Crimson Caravan and the Van Graffs

Kill Alice McLafferty and Gloria Van Graff

Head for either Crimson Caravan Company and Silver Rush. It's up to you to choose which area to head to first but both areas will have a lot of guards so be prepared to fight. After killing Alice McLafferty and Gloria Van Graff, talk to Cass to conclude this side quest.

Prove the Crimson Caravan Company and Silver Rush Guilty

For this objective, you can choose which area to head to first. At Crimson Caravan Company, you can find the evidence in the safe beside Alice McLafferty's desk. This will require a 50 Lockpick skill check to unlock. At Silver Rush, you can find the evidence inside the safe found in the inner office.

You can get inside the room by pickpocketing a one of the Silver Rush guards or by passing a 75 Lockpick. The safe itself can be unlocked with 75 Lockpick or through the terminal with 75 Science. After gathering both pieces of evidence, talk to Jackson at the Mojave Outpost then talk to Cass to complete this side quest.

Best Choice for Heartache by the Number

Don't Kill Alice McLafferty and Gloria Van Graff

When choosing how to help Cass deal with the Crimson Caravan and the Van Graffs, we recommend choosing to get evidence of their crimes and have the NCR deal with them.

Going with this route keeps your NCR reputation unblemished while also unlocking the Calm Heart companion perk for Cass which gives her additional health points This allows you to focus on taking down enemies without having to worry much about Cass's wellbeing.
