Three Dog

Three Dog is the radio host and news anchor of the Galaxy News Radio station in the Capital Wasteland in 2277, playing music that likely would have been heard on the radio in the years leading up to WWII, as well as the immediate post-war era.

Background
Born to parents who made their way in the world as members of a traveling theater group, Three Dog grew up listening to rock music, hating the government that he never knew (but surely caused the nuclear holocaust), and fully believing in the rights of free speech and communal law. At some point before he established GNR, he was taking Jet and stumbled across Oasis.

He established GNR in 2272, together with Margaret, a radio technician. Should Three Dog die for any reason, she will replace him as the radio host. Since he began, he's been broadcasting to the Wasteland with his voice, public service announcements, and music. At times he makes jests at Enclave Radio.

Three-Dog believes in what he calls 'The good fight', which boils down to noble pursuits in the fight against raiders, super mutants and the Enclave. This explains why he cooperates with the Brotherhood of Steel.

Daily schedule
He stays in the GNR building throughout the entire game.

Quests

 * Following in His Footsteps: Passing a speech check will give you immediate information about your father.
 * Galaxy News Radio: Failing, or not taking the aforementioned speech check starts this side quest. If you pass that speech check, you can immediately reinitiate conversation to have both quests running up at the same time. You can also come back later, or see him for the very first time after having made progress otherwise in the main quest to find your father, and if you bring your support to his "good fight", Three Dog will also give you this quest.
 * The Search Continues: Killing Three Dog before he tells you to go to Rivet City at the end of the Galaxy News Radio quest starts this quest.
