I disagree, I don't think she hates the MC at all nor do I think that there is "no change in her" towards him. I think she's a confused, scared and even traumatized young woman who has built inner walls as a defense mechanism. Why? Not certain yet, maybe it's survivors guilt, maybe it's something that happened between her and the MC previously or maybe she blames him for her mothers' death. We will need more info before it becomes more clear, but either way we have seen moments in which she does let her guard down and opens up to the MC. Now it's been a few months since I played this, but in my play through I recall her having moments were even she seems confused as to why she's so angry at him. I'm sure it will become more clear in future releases, but I don't think she's a toxic person...just a young woman who is dealing with some emotions and baggage she hasn't figured out to handle yet.
I think it may be more to it than that......if I remember right, I think there is a condition for girls called Electra complex or something like that. (basically where the daughter is trying to get rid of the Mother and take her place as a Wife)
I don't think Macy is struggling with blaming Dad for Mother's death....so much as, she probably had a thing for the Dad for a long time and wished that the Mother would just die so Macy could then take her place.
The Mother then passes away....not sure if it was said how (don't think it was though), either by accident or sickness.
Anyway, I think deep down that Macy blames herself, for having wished it to begin with.....and then it happened, and now she don't know how to deal with it.
She still has those same feelings for Dad, and wants their relationship to move forward, despite her blaming herself.
I also think the first and last scene, where the Dad kisses her and snaps out of his stupor.....first calling her the dead wifes name and then panicking when he realizes its Macy.
Not only did it shoot guilt in Macy for Mom, but may have also felt like a direct insult and rejection from Dad...at the same time. That's when she cocked back and floored him good...Lol!!
I bet in the morning she'll have a different take on it (having had the whole night to cool down and think) and she'll have to then open up and have a serious talk......followed buy hot sweaty animal sex with him after...Lol!!...................Peace!!
