Gavin was most likely born somewhere in the British Isles. Later in life, he, along with his friend Nigel, decided to leave Britain behind in their pursuit for a new life, and chose the United States as their destination. So, at some time prior to 1899, the two embarked on their journey and reached America.
At some point after reaching the New World, Nigel woke up and Gavin was gone. In 1899 and 1907, Nigel can be seen traversing the map in search for his lost friend.
Gavin himself is not seen in the game, however, his friend Nigel can be encountered on numerous occasions throughout the game. He tells the player about how he woke up one morning to find that his best friend, Gavin, had disappeared and still has not been located.
- Gavin is not seen anywhere in the game.
- The player can encounter his friend Nigel in 1907, where he appears to have gone insane due to the excessive searching. He appears much more unkempt and stressed than he did eight years before.
- It is possible that Gavin left Nigel after an argument, which is implied through Nigel's dialogue, although Nigel states that he believes Gavin was "taken by someone".
- It is implied that Gavin simply doesn't exist and that Nigel may suffer from dissociative identity disorder. The Letter to Nigel from Tom that can be found after looting Nigel written by his friend, Tom, refers to both Nigel and Gavin's mother as the same.
