As a nervous habit Jason will twirl his hair in his fingers
[HEADCANON #3]
Jason is actually a huge wimp when it comes to anything spicy
He'll take one bite and his face will turn bright red

Jason absolutely loves doing other peoples hair, he finds it to be very therapeutic and one day he hopes Puppeteer will let him braid his hair
