The Family Guy/Hey Arnold! Theory

In the mid to late 90s there was a dysfunctional family called the Griffins. they were well known in their hometown for how badly they physically, mentally, and even sexually abused their three kids Meg, Chris, and Stewie. they have also committed various others crimes such as murder, cheating, theft and assault. Here's the stories of the three children/victims of the abuse,

Meg

She the oldest and was abused the most. Whenever something happened she'd always be blamed for doing it. This caused her to be very depressed most of the time and only had a few friends, though she has had some luck with guys, most of the time she isn't at all. As for her treatment by her family, they beat her, insulted her, almost got her killed, and never seem to care about her.

Chris

Who was the second oldest and suffered from obesity and other problems. He really likes films such as The Silence of the lambs, and was the only one who cared about his sister, Meg. He was being stalked by a pedophile who prayed on other kids too, though luckily he never was victimized. He and Stewie were probably treated the best out of the Griffin's kids, though sadly he was stilled being abused by his family.

Stewie

Stewie was probably the second most effected from the abuse after Meg since he was between the ages of Newborn to 3 when the abuse occurred. Due to being very young he couldn't take care of himself, so he'd always be left with Brian, who was the family Dog, who was actually very good at taking care of him. He suffered from hydrocephalus which is the reason why he has a football shaped head. He also imagined he spoke with a Cockney accent similar to his older brother Chris. And even though he knew about many basic things in life due to his parents Peter and Lois doing very adult things near him. he thought that this was normal, and that's why he imagined various violent and sexual things in his head like killing his mother, having sex with Brian, having adventures with him, and even imagined what one of his aborted brothers would have acted like.

THE DESTRUCTION OF QUAHOG

A group of 7 Politicians; dubbed the "Libral 7" had arrived in Quahog after being told about the town, but when they finally got there they saw it as ok, but then they were told about the now infamous Griffin family, and that would be the day when abuse finally ended for the Griffin children. When they arrived Peter tried to distract them, but 6 of them entered anyways and saw that Meg's dead body was being taken to be eaten by her family after she committed suicide, and then one of the men in the group asked Peter "Did YOU do this?", thinking that he wasn't going to put him in jail he said Yes, and that was the last thing he said before Quahog was destroyed by the Libral 7. Both Peter and Lois were arrested and given 50 years in prison.

THE FATE OF THE GRIFFIN CHILDREN

Sadly the Libral 7 couldn't save Meg's life as she had already died. She had committed suicide by cutting herself all over her body. It was later learned that she secretly indentified as a transgender man, but her parents would not allow her to have ANY form of sex reassignment surgery, and it's believed that this is one of the many reasons why she was being abused.

Chris now remains mostly anonymous, and his life after the abuse stopped is unknown, though it is known that he has since gotten married.

As for Stewie, he had his name legally changed to Arnold, and he currently lives with his adoptive grandparents in the Bronx.
