I'm confused about a certain character's fate in season 3. *Spoilers*
Can someone please explain to me what happened to Arthur's father in season 3? He agreed to go back to complete his mission after talking to Dr. Whittison, but at the end of one of the episodes a mysterious person puts a gun to his head while he was trying to rest in an abandoned building.
They then just never really follow up on that, unless i wasn't paying attention. Was Roy Milligan really killed? If so, who the heck was the mysterious person?
