Why did the DM get so bent out of shape about Freya and Martin but not the fact that Freya was pursuing Bunker?
Nothing ever really happened with Freya and Bunker, and he doesn’t know what happened with Freya and Martin. Mostly though, it has to do with the different nature of the DM’s relationships between himself, Bunker, and Martin. (We’re talking about them in their “real lives”, and not them in the game.)
The DM trusts Bunker, and doesn’t consider him to be a threat. They’ve been friends a long time and had a steady friendship. The DM does not trust Martin, but he also kind of looks up to him. This results in the DM being a little more insecure around Martin than Bunker.
