My guess why HC ended the path where he did
It is to give players the freedom of imagining what happens next. People that want Harry kill them and then go on a run can imagine that. Others my want to see Harry commit suicide. Finally some will be of opinion that there is no way Harry could kill Luca because Luca simply is far stronger then him. Hell maybe it is only Laura that returns, he fails to kill her wimp as he is and just ends up in psycho.
Technical side:
During Harry PoV there is Laura pov sequence - i don't think it is intended.
In CG there are full CG for business trip phone scene but there is no scene. Is that right? Is the scene planned?
2C about route
Harry here has been more annoying then usual, when he was blind i could blame his trauma for it. But here he is aware ? almost ? like he is basically sure Laura is blackmailed but he can't connect the other dots. He can't get any answers, he is such a pushover that i can't stand him.
The scenes, kinda shame we don't get the window and "massage" scenes. They probably weren't made because they are more of the same scenes from family path... but i really liked that path.
