I'll reiterate a couple ideas I shared with Raven elsewhere, for the benefit of everyone here in case both get used (there'll be textures related to the first):
* There's a lot of MIDA goons on the Marathon, foreshadowed by their marks being left around the ship. The SO may have to fight them directly at some point.
* Strauss might be encountered face-to-face, where he nearly blows his cover by referring to the SO by name (maybe) when it's unlikely he'd know that, and acting like he's the one meant to order them around. The SO and Durandal have to cooperate with him for a while; eventually he gets away, and the SO is able to access the communication logs. Another MIDA agent was yelling at Strauss because Durandal called the Pfhor instead of raising hell on his own.
Will discuss some others I had if any are at least filed under "possible".
