Suspicions at the Supply Depot
This quest becomes available once you complete both Brotherhood of Steel Quest: Show No Mercy and Brotherhood of Steel Miscellaneous Quest: The Lost Patrol. Captain Kells ordered you to investigate some missing supplies at the airport. Report to Knight-Sergeant Gavil in the Boston Airport supply depot for more information. Ask about Lucia and Clarke.
Your first suspect might be Knight Lucia, so talk to her about the recent activities.
Your second possible suspect is Initiate Clarke.
Knight-Sergeant Gavil directs you to find evidence. Board the Prydwen, and find Clarke’s and Lucia’s sleeping quarters on the lower main deck. Their footlockers are locked (Novice). You can:
- Pickpocket either key from them in the supply depot.
- (Novice, Expert) Pick the lock of Clarke’s and Lucia’s footlockers.
- Or find Clarke’s key on his bed, open his footlocker, find Lucia’s key inside Clarke’s footlocker, then open her footlocker. Amass the following, read the note, and read her log.
SHADOWING THE SUSPECT
Now that one of your suspects has been acting suspiciously, return to the supply depot at Boston Airport. Lucia grants you more information. Locate and follow your main suspect at a safe distance. Back away after speaking to them if you’re seen. Your suspect disappears into Boston Airport Ruins.
There’s a little-known underground area of ruins under the airport, including an old subway station and baggage claim area. The place is filled with Ghouls and some of the least pleasant water you’ve ever waded through. Along the way, dart into a dead-end corridor and discover Knight Rylan. Gather his Holotag. This enables more conversation choices when confronting your suspect.
Continue to explore the ruins, culling Feral Ghouls. Destroy them all if you wish (or they are destroyed once the quest is complete).
When you finally catch up to your suspect, you can:
- Kill them without a conversation.
- Provoke them in any way, turning the suspect hostile.
Or convince the suspect to go into exile. They leave the airport, though you may meet again during a random encounter later in your adventure.
Or promise to lie about your discovery.
If your suspect is killed or pickpocketed, you can gather the following:
After dealing with the culprit, report to Lancer-Captain Kells on the Prydwen. Your options here will vary depending on how things went in the airport ruins, but basically, you can:
- Lie about the thefts. If your suspect is still alive, they remain working at the airport.
- Or tell the truth. If your suspect is still alive, they are imprisoned at Cambridge Police Station. During Railroad Quest: Precipice of War, you can optionally free your suspect if you subsequently side with the Railroad.
You receive a reward from Kells. This is usually Bottlecaps. However, if you managed to persuade Clarke to turn himself in, you receive a special Power Armor part.
