[TSR Nik's Route] Questions regarding Choices and Consequences

Spoilers for TSR Build 36.

Recently finished Nik's route with the good ending with after credit scene. I still need to go back and finish the bad endings; but I had some questions that I was wondering if someone smarter than me can help answer.

  1. What is the significance of giving the one accomplice name to Porter? What does Porter use the information for, and how does that result in whatever happens?
  2. Right at the end, Yao places the two original double eagles he had possession of on the two graves. Was it implied that Blithe was the one that found the double eagles? Did Yao take it back from her?
  3. Probably answered through playing, but what would the significance and consequence of distrusting Yao and being hesitant on Nik? I do remember bad things happening to Sam, but I'm sure there's a theme there.
