I have a super crazy theory

1) Melissa, Rafael and the Sheriff are keeping a secret, which is bad enough that they want to keep it from Scott

2) Stiles knows the secret, and he has kept it from Scott for years, and he is still keeping the secret now

3) The Sheriff and  Rafael don't like each other much because of this secret, but they still end up being friendly in the last couple of episodes

4) NogiStiles says Melissa called the Sheriff after "it" happened, making it sound like it was a singular event. Seeing as Stiles overheard, it is likely Melissa called the Sheriff at home.

5) Rafael used to have drinking problems

From 1, it can be inferred that it is Melissa's fault, because if Scott were to know about it, he would probably feel betrayed by the one he loved the most/trust the most (can't remember where they said that Scott preferred his mom more than his dad even before the incident.

However, when we bring in number 2, this is where it starts getting tricky. If you were to overhear a dark secret about your best friend's mother who can also be called as your brother which can provoke a severe negative response from him if he were to know, how would you view that person's mom? As we have seen so far, Stiles has been viewing Melissa in a positive light/as his own mom. So what reason is big enough to trigger a negative reaction yet still be forgiven?

Melissa trying to seperate herself together with a child with her husband. From 5, it is already established that Mr McCall used to be an alcoholic. And what does alcoholics do best? Violence. He probably beat up Melissa and Scott everyday. So most likely, one day, Mr McCall became so violent that he was going to kill or do something horrible to Scott that Melissa had no choice but to step up. She fought/wrestled with Mr McCall and in the process, accidentally severely injured Scott herself. Feeling frightened, she called Sheriff Stilinski. Also, seeing that Mr McCall can't really remember what he does when he is drunk, she decided to push the blame/frame Mr McCall and used this opportunity to divorce him. As a result, Scott felt betrayed that Mr McCall would do this to him and hated him.

Thats why, if the truth were to be known, Scott would be horrified that kind Melissa would do such a villianous(?) act and would hate her.
