This unnamed gun store owner resided in Alternate Earth.
Background[]
After the angel Virgil arrived in the Alternate Earth in search of a key held by Sam and Dean, he discovered that he did not possess any of his powers due to the nature of this new world. After Virgil obtained the key, he contacted Raphael using Misha Collins' blood and learned that he needed to return to the spot from which he came through in order to get back home.
Virgil visited this man's gun store and obtained two Berettas and a shotgun. The man was impressed by Virgil's knowledge in firearms. Virgil responded by explaining that he was Heaven's Weapons Keeper, which confused the man. Virgil then knocked the man in the head with the back of the shotgun and left him unconscious while he went off and used the weapons he stole to slaughter the Supernatural crew who were surrounding his exit point.
