Everyone needs something.

[Shigaraki was able to ask for things. There was a stipend for his care from the state and U.A.'s ridiculous budget on top of it. Denying himself would just lead to more agitation, more scratching and more scabs. If they wanted to leave him to rot in prison, they would have. The doors open and they'll head out into the lounge area.]

Eri, you can head back to your room, if you want. We're going to talk a while longer. [Another gentle pat to the girl's head. She nods and scurries off, down the hallway to the rooms. He'd have to show Shigaraki around soon, set him up in his room, let him unpack, but there was one last thing to check.]

Hey. [Once Eri was out of earshot. She didn't need to know every detail. As far as he was concerned, Eri could think Shigaraki was the same as her: a victim of circumstance.]

What do you want to be called, now? [Shigaraki Tomura. Shimura Tenko. Aizawa didn't care much either way, he would work with either, but which one was easier to hear at this point?]
