She was to be an integral part of the broken Find Children spy in the Followers quest.
As a scout for the Followers of the Apocalypse, Heather's primary duty is to aid scouts in raids against the Children of the Cathedral.
Sometime before the Vault Dweller arrives at the Boneyard, Heather secretly joins the Children of the Cathedral and begins spying on the Followers of the Apocalypse and reporting their actions. The reports give the Children a clear advantage over the Followers and soon prompt the Followers to deduce that there is a spy in their midst.
- Find Children spy in the Followers: Heather is the sought for spy.
During investigations into the presence of the spy, Heather continually tries to manipulate the Vault Dweller into believing the spy is someone other than her. Despite these deflective attempts, the Vault Dweller soon deduces Heather is the spy, and she promptly attacks him in order to ensure none of the other Followers discover the truth.
Heather was set to appear in Fallout, but was either cut from the final version of the game or never properly implemented.
