This is the FIFTH time I've requested that you allow me to release our supply of headphones and personal audio listening gear to the residents. It seems unfair that residents are required to listen to their music selections in the studio rooms.”— Intra-Vault Mail 000476
Gordie Sumner was a resident of Vault 92 and possibly its supply manager.
He wondered why the overseer did not allow the Vault 92 residents listen to their recorded music with earphones in their private quarters. When he realized that the other residents were going insane, he made a deal with Dan Kobachesky to obtain a weapon to "be prepared".
Gordie Sumner is mentioned only in Fallout 3.
Behind the scenes
Gordie's name is possibly a reference to rock musician Sting, whose given name is Gordon Sumner. The first name "Gordie" is also most likely a reference to Sting's hometown of Newcastle upon Tyne, England; the natives of which are known as "Geordies".
