[He's a manchild groomed for villainy. Of course he never had any experience with children or socializing normally with people his age. Hell, he had a hard time making friends even in the League or with people who had similar goals like Stain. Always demanding that they go "die immediately" when they didn't match the descriptor he'd gotten about them or picking fights.

But it didn't have to be that way forever. The simple fact that Shigaraki came out of his room because Eri was in the common area was a big leap forward. But it didn't exactly teach him how to behave around others or that it's ok to have relationships that didn't hinge on him being the center of the universe.

Shigaraki doesn't go back to his room even though Aizawa had been firm with him. Instead he peers over at the easy puzzle Eri was opened to and pointed at one of the numbers.]

You want to have one in each row and column without repeating. There's only two more threes that can fit, do you see them?

[Unsure if he's doing a good job helping, his other hand sneaks to the back of his neck, picking at it relentlessly. He avoids looking at Aizawa, certain that the guardian knows what's going on. He doesn't want to get called out for his bad behavior so he chooses to hyper fixate on Eri's puzzle.]
