Yeah, the fact that gatekeeper takes the name of his current position is going to make things a bit wonky for some folks who don't keep up.

Gatekeepers new title will be President? Herr Fuehrer?
I am actually hoping, though it is a very slim chance, that Markus survived the coup and actually had Gatekeeper's rebellion squashed. But I'm thinking this is more likely the case:

Gatekeeper to radio: "Who the hell do you think you are, asking for me on my radio, by my real name?"
man on radio: "Come now. Is that any way to speak to me?"
Gatekeeper: "Durai?!"

I get the feeling Gatekeeper is a former Eastern Bay inmate, possibly even a former Sister.
