This one, like some of the others, may make your head explode. Or, it may be an easier pill to swallow, depending on your perspective.
The reality of Who Killed Markiplier? isn’t our reality. It’s an alternate universe.
So Mayor Damien and the Colonel? They’re definitely Dark and Wilford… but not the Dark and Wilford we know. Damien is Dark with a conscience – a softer Darkiplier, if you will. And the Colonel is a Wilford Warfstache who never became a talkshow host, but stayed in the military instead.
