So whats the deal with Susanne's love life? I get that she was dating Noah and seemed pretty infatuated with him, based on her diary and the whole covering up his involvement with a kidnapping thing . But then the game abruptly does a 180 and says she and Cyrus were engaged?

I haven't read the book and I am greatly confused. I feel like I need some kind of timeline, because Susanne did not have rebound vibes when she was with Noah. Yet Cyrus is willing to commit a murder as vengeance for her and (I presume) still has a good relationship with Susanne's father . Was their relationship just super unbalanced? Did I miss some plot explanation?

I also thought it was strange the game never revealed Noah's face. What difference did it make to the story? I figured there would be some kind of reveal, but it never happened. Plot wise, Noah is more important than several of the train guests so why didn't they give him a face?
