Wilfred was also an old friend of Jon Elwood, the director, going back to their days at the C.I.T. campus. After Jon ordered the lockdown of the labs when the bombs fell, he was the first one to try to find a way out. He eventually locked himself in a small part of the labs and tried to hack his way out. When Mary tried to get the U-238 from the isotope containment, he locked her in there. In his office, there is a single feral ghoul.
Wilfred Bergman is mentioned only in Fallout 4.
