Here's the story you never knew about the FNAF sotm… it's a tale about an abused child finally finding a caring yet tired adoptive parent
(yes I love fanfic ideas & I love this idea)
After looking at a few other posts that I just reblogged and thinking about The Mimic and Arnold stories you realize how similar their stories are
When it comes to the people around them:
They're both being taken advantage of and abused by those higher above them
Ignored and deprived of personal needs
until inevitably one of them snapped and fought back after losing the thing that it loved the most the child that it looked after
The other one on the other hand had many options to leave and escape and was able to help one of them who went on a rampage simply because it was taught violence
If you think about it M2 is really like David if the kid was taught violence in real life…the story of SOTM from M2's perspective is literally the story of a child who was created after no one was around to look after their sibling, and once that sibling died all they were left with was an abusive father, who couldn't stop being reminded of their original child who they lost, and they can't love the second child anymore, So instead they lash out at the kid essentially abusing them until inevitably that kid snaps back, no longer taking that abuse because… that's all he's known.
The only person who ever gave him love was their older sibling
Think about it, David is M2's older sibling, the one who taught him love and care, that's why in the secret ending anytime you get the story correct it reverts back to being the sweet David that we've heard in the story, but the people who taught him negligence and violence was their father (their creator whatever you want to call Edwin) and it was only when their father needed him most did he decide to not give him the time of day, ignoring and neglecting him the same way Edwin had done to M2
In all honesty you could say David was The Golden child and M2 was the scapegoat child. Yes Fiona did Love David, but since she wasn't around to help M2 to understand care and love from an adult's perspective they never learned that perspective, and the only love that he ever felt was that of a child that's why the only time he ever shows love to Arnold throughout the game is when he's treated like one
With all that in mind do you honestly think Arnold's going to allow fazbear to have the mimic, I doubt he would have. I honestly do think that (even if it means losing his job) he would have taken M2 with him, because he's seen firsthand what could happen if you abuse that poor thing, it goes on a rampage… kind of like a teenager would in a way of protecting their family or themselves
In all honesty I seriously doubt that the mimic we see chasing Cassie is the same mimic that we see chasing Arnold around. The body is different it's not as flexible as it was in SOTM, and we know for a fact that the reason why that mimic in ruin is burned is probably due to Fall fest, not Edwin's home bursting into flames (if the books are to be believed which I think they should).
Yes this game technically takes place in the past, making Arnold the oldest FNAF protagonist we have so far that's still (probably hopefully) alive, and if that's the case then the mimic we see chasing Cassie has to be one that was learning specifically from Afton not one that was learning from an Edwin
Edwin was a good dad at one point to his kid, and while he was neglectful unlike William he realized his mistakes he made with both M2 and David, & he wanted to atone for what he did to David, and he did apologize to M2, but by the time he finally realized what he had done was wrong it was too late, for everything he had worked for he lost all of it. His wife, son and his adopted/created child
This goes to show that just like a child if you raise an AI correctly it can be an amazing thing and it can help you in many ways, but if you hurt them and treat them like they're beneath you or just objects, then of course they're not going to help you back. Why would they want to help and reach a hand out to their abusers ,it isn't going to happen and that's essentially what the mimic and Edwin's relationship was. Before Ed programmed M2, their relationship wasn't too bad (M1), but once he put the M2 software into the mimic the relationship became that of an abusive father in an innocent child one that snapped because of the abuse
