Step-by-Step Walkthrough

1. Initiating the Quest

   • Begin the quest by speaking to Deacon, who can typically be found in the Railroad’s hideout in the Old South Boston area.
   • Accept his task to go undercover within the Brotherhood of Steel.

2. Meet with the Brotherhood Initiate

   • Travel to the Cambridge Police Station, where the Brotherhood is based.
   • Approach the Initiate, who will inform you of the ongoing situations in the Brotherhood.
     • Ensure you’re equipped well, as some members may be hostile upon your arrival.
     • Utilize stealth if you wish to scout out the area first.

3. Gain Trust within the Brotherhood

   • After being accepted by the Brotherhood, check in with Paladin Danse or Elder Maxson.
     • You will need to progress with the Brotherhood quests to further ingratiate yourself with them.
     • Complete at least one mission for the Brotherhood, such as "Learning Curve" or "Defend the Castle".
       • Focus on gaining their trust while gathering information about their synth beliefs.

4. Collect Intel on their Activities

   • Listen carefully during conversations at the Cambridge base. Information about their synth-hunting operations will help you fill in Deacon on what the Brotherhood is planning.
   • Keep an eye out for any plans concerning the Railroad or their synth retrieval missions.

5. Return to the Railroad

   • Once you’ve gathered enough intelligence, fast travel back to Railroad HQ.
   • Speak with Deacon about what you've learned regarding the Brotherhood's intentions.
     • You will have a decision to make based on the intel: either support the Railroad or give up the information to the Brotherhood.

6. Final Decision Making

   • If you choose to inform the Brotherhood of the Railroad's plans, you must report back to the Initiate.
     • This will jeopardize your relationship with the Railroad but may benefit you with the Brotherhood.
   • If you decide to keep the Railroad's activities secret, prepare for a confrontation with the Brotherhood later on.

7. Concluding the Quest

   • The quest concludes based on your decisions and your affiliations.
     • If you maintain loyalty to the Railroad, you will help them continue their mission without the Brotherhood's interference.
     • Alternatively, siding with the Brotherhood may provide you with their advanced technology and support.
