In multiple instances where Information can be obtained you can stop by and talk to Brand who is sitting down near the entrance to the mill. He mentions he trades information to Ashur in exchange for time off. He asks that if the Lone Wanderer learns anything, they should pass it along.
There are 5 pieces of information you can give Brand:
- "I'm here to find a cure for the mutations."
- "I'm from outside The Pitt. I'm here to help free the slaves."
- "Midea is helping Wernher."
- "Wernher is trying to free the slaves."
- "Marco is making weapons." (This option kills Marco instantly.)
Ultimately, this quest has little effect on the outcome of the storyline of The Pitt.
