Edgar Ross

Edgar Ross is an agent for an unknown body, althought is is suspected he is working for either the Bureau (Predesessor to the modern FBI) or a Pinkerton (a private military contracter similar to Blackwater) who supposedly has kidnapped John Marstons wife (if not his whole family) to coerce Marston into working for them.

In the new trailer Ross rationalizes his actions by saying his alternative is hell.
