Just to make sure one more time, in case if I misunderstood something, dev said there'll be a path to get rid of this stuff anyway, even if there will be some scenario points players would pass anyway?
I don't really understand the question.
According to what is known so far, there will be two paths, one where Max is (probably) friends with Eric and one where he openly oposes him.
The plan for the **OLD** build was, that at some point Eric gets kicked out one way or another (it was only implemented on war path, but never finished on the others).
But since he is Ann's boss, he would still be a nuissance in the future. So yeah, he will be part of the story and no, you don't necessarily see him screw the girls. Most substory arcs don't involve him in the first place, he is not the center of the game.
