CASE 318: KEVIN WAGNER
Resides and works in Seattle, Washington, United States.
He is employed at a startup company dealing in the tea market.
While watching television on his phone at night, it switched via a "weird distortion" to a channel where people were waving British flags and singing "God Save the King". In his view, it was as if the United States had lost the Revolutionary War.
Note, this is similar to Case 42.
