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".

Trivia
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".
