He first tasks Nicholas Raine to get his hands on a Cuprino in order to deliver supplies to the Watch Tower. Afterwards, he gives the quest "Destroy the Bomb Caches" in order to stop the Shrouded Clan RC Bomb Cars that have been harassing people who passes by the Shrouded territory.
After destroying the bomb caches, he thanks the protagonist and tells him that it's good having people like him around. He then asks him to check on the Mayor. He will then be standing there either checking the computer on the table or tuning the radio that appears to play the distinctive Wasteland Radio music.
Later, the protagonist acquires a mission protecting the Sheriff from the Authority during "The Exchange" from the local Job Board. He is not heard of, seen or mentioned again after completing the quest.
- In the novel, Sheriff Black is a rather vicious character as he threatens to sell Nicholas Raine off to the Authority unless he entertains the people of Wellsprings by participating in Mutant Bash.
