Gene

Gene is a right nutty geezer appearing in Fallout 4.

Background
Gene wanders the Commonwealth to sell dogs he raised himself, albeit begrudgingly, stating that he "feels blue for a week after selling a dog".

Other interactions
Gene is a character that the Sole Survivor may meet in the Commonwealth as a random encounter. If the Sole Survivor is able to pass a Charisma check of 6 or higher, he will offer the Junkyard dog for 250 caps.

Gene can be encountered multiple times in random encounters, and he will be willing to sell a new Junkyard dog on each new encounter.

Appearances
Gene appears only in Fallout 4.
