Bethesda waited until June to even confirm that Fallout 4 existed. In a new interview, the developer explained why they waited so long to announce the post-apocalyptic RPG.
Galahad is the main character of The Order 1886 and throughout the game, players can notice that he lacked any proper reflection on surfaces with a highly reflective material e.g Mirror. This led to a fan theory speculating that Galahad was a Vampire, even though the developers never intended this to be the case here.
