I think there's a lot of reaching going on currently. There is nothing currently in the game to suggest Emily is not our real mother.
The truth is, even if she is, or not his mother,she has allready fucked MC's life
let me see the story with his eyes :
MC had a happy childhood and then out of nowhere BoooooM his dad left and leave him alone and until today he doesn't know why
MC is still a boy less than 12 so he is through his own hell,he must deal with his own Demons from his lost
so goes home finding his mother crying, and drunk, sitting on the floor, he gets down to her level of eyes and he talk to her
what possibly said :Mom I'm here for you, help me to help you, stay with me and we can pass this together
He was just asking for her love, someone to be there for him. But she gets that help from Melissa,she is not there for him, she is lost .Luckily thought here is her dautgher ,Erynn and he get the huppines that is missing from her
Erynn is now replassing his mom and dad ,is his best friend everything in his world (MC said we were inseparete) until
the time that she become popular ,made new friends , and she forget our boy ,he is 12 and he is loosing again what made him happy,so he become jealous
SO he is left alone for one more time
He get the courage to confess, NOT his LOVE, but that he likes her, telling her really
" hey i'm here ,i need you " beg her to be part of his life
Remember the image, that she just pet him on his head, and her friends make him a joke (that what he remembers or want to remember ) traumatic experiances that he wants to forget psychological , physical or even been threatenent from Ethan
Our boy become more and more angry ,nothing really maters ,everything is just the same , his attitude a school and home was not rebellius was just "asking for help "but noone was there for him
Again he was alone, angry, begging for his mother love,for hers atention,but noting so he start building with his own pieces a wall around his heart ,so nobody never ever hurt him. His mother find the best sollution,threw him away , where?,to his father
who is the one to blame ,(that is what the boy thinks)
end of part one , later the crying mother "again"
and how to loose something that you lost 5 years ago
