Brimstone was an agent of the Railroad who was killed by B-263.
Background[]
Brimstone hired B-263 as a detective to find her long-lost mother. However, she eventually found out that B-263 was actually a synth working for the Institute, with the mission to discover the Railroad's hideout. B-263 killed Brimstone before she could blow his cover, but he managed to extract the names of other Railroad agents before her death.[1]
