you used to be a villain but had gotten fought but instead of young to jail Aizawa offered to take you in for rehab to bring you into a better state and maybe become a hero. One day as you were in the dorms with everyone else you had a small knife to cut some food but as soon as you grabbed it Aizawa snatched it from you.

Aizawa:"Again no sharp objects."

he said putting the knife back.

"Why not?"

you asked and looked at him and be let out a sigh

Aizawa:"I neither have the patience nor the crayons to show you."

you pulled some crayons our of your pocket and held then up innocently.

Aizawa:"why do you have crayons....?"

"Just in case you have to show me something."

everyone in the dorms died of laughter and you gave a little snicker, still holding the crayons.
