Shoto wouldn't really understand his brother's age regression, but he'd do what he could to encourage it, because he can tell it makes him wayyy calmer. he would really like it if Touya felt safe around him, so he makes sure to be quiet and gentle when he visits his brother. he brings the snacks that his siblings tell him Touya used to prefer, softer clothes, stuffed animals (which he rather enjoys, himself, but only when their fur is the right texture). he thinks he's probably supposed to be his brother's caregiver, and once he's let that idea process, he likes the idea of having his brother rely on him in that way
and once he convinced the guards at Tartarus to release his brother into his custody—because no way is he letting Touya get dragged back to the Todoroki estate, not after the last time Touya was on the premises, not after he stood and prayed at his own shrine—he'd make sure Touya's room was decked the fuck out. it's a perfect room for little!Touya, all covered in stuffed animals and Shoto's new hero merch, games and toys and everything he thought a younger Touya could ever want.
everything is soft, and all the sharp corners on the dresser and bedframe are padded, just in case Touya slides a little smaller than he usually is. shoto doesn't want anything to happen to him, after all. that, and he's a little concerned about Touya trying to use his quirk and hurting himself, so he can't have anything in the room that could act as a temptation or a trigger.
Shoto who is not quite mentally an adult, either, and who is stunted from a lethal childhood abuse/autism combo, but who is definitely big enough to give Touya anything he wants or needs. plus, because he's not totally Big with a capital B, he can actually enjoy it when Touya wants to play games with him or watch cartoons. Shoto who is not-so-secretly smug about being a way better caregiver than Enji. Shoto who feels really proud of himself for enforcing safety rules with Touya, and Touya who really enjoys having super clear-cut ways that he can be good and receive praise from the person in charge of him.
when Dabi occasionally fronts, he acts like he hates the whole setup, but he definitely still snuggles with a favored stuffie while he waits for his brother to get home from patrol. he should be more annoyed that Shoto thinks he needs all this coddling, but he's honestly not. not really. everything is soft in Shoto's apartment, and he has no reason to cause problems, anyways. he'll just cuddle with this stuffed dog and be patient, 'cause there's nothing else to do. he's bored, he's definitely not cozy and safe and missing Shoto with his whole heart. he's definitely not going to be over the moon when his brother finally gets home.
ah, cuties. I love when Shoto is a little confused but wants so badly to help Touya heal. I'm on a dabisho kick right now and cannot be stopped. send dabisho hcs if ya got 'em and I'll eat them all
