Bannon

Bannon is the owner of Potomac Attire and a member of the Rivet City City Council.

Bannon thinks that he is the most important person in Rivet City and when asked about the history of the city, he will tell you he is the founder. This is not the truth. But that doesn't stop him from telling you. He also apparently has a "social problem" (STD) as noted by Doctor Preston on his terminal.

Unmarked quest: Council Seat
Bannon mentions that his council seat is being contested by Seagrave Holmes. He wants you to look for incriminating evidence against his opponent, which can be found in Seagrave's room (under the bed, leaning against the footlocker). The key for the room can be pickpocketed from Seagrave.

Once you have obtained the evidence, you have to side with either Bannon or Seagrave Holmes. Denounce the other to Lana Danvers and collect your reward. If you complete the quest in Bannon's favour, he rewards you with Deathclaw Gauntlet schematics and a permanent 10% discount at his shop.

 only appears in Fallout 3.
