On the topic of food insecurities
Jason has to eat what he can to survive as a child, never knowing when he'll eat again. Sometimes he eats the same things over and over.
I see him, while he's taking care of his coked out mom, getting groceries but only buying things to make sandwiches with because he doesn't know how to cook. So he's eaten a lot of sandwiches, every day, a few times a day maybe, over the course of a few years.
And he had to, it was all he had, all that was cheap at the time. He couldn't risk getting anything else, it was too expensive. He'll settle for sandwiches, it'll be fine. But after a while, he's eaten so many sandwiches that the very thought of bread makes him mouth dry and bitter. So he starts eating all the components of a sandwich, minus the bread.
He's eaten so many bread and probably cheap cup noodles that he can't stand them anymore. With his time with Talia and thw league, he refuses to eat anything with bread or noodles. Even if he does eat them, he just starts to get so sick.
Jason has food trauma with extremely cheap food options.
