Parr Family Secrets !!install!!

Dash is a boy with super-speed, forced to walk at a human pace. In the first film, we see the result of this suppression: a bitter, acting-out child. The "secret" here is the cruelty of the constraint. By forcing Dash to be "normal," the Parrs were slowly breaking his spirit. He was relegated to being the class clown and a troublemaker because he had no other outlet for his physiology. The family knew he was fast, but they forced him to keep it a secret even from his own reflexes, leading to a build-up of kinetic energy that manifested as behavioral issues.
