The problem with hooking Marta and Schiller up..
biggest thing that makes that basically vile, and would irreparably taint the lead heroine to the audience...the fact that Schiller casually and cold-bloodedly killed 'their guy" on the docks...who was a pretty cool guy down on his luck, that they exploited and manipulated to drag into their scheme...then he gets dead for his trouble while having played ball for them.
So her being fond of that guy...shes then going to start fking Schiller???
Itd be a little odious, unless it was all part of a greater revenge plot.
