Don’t think about baby Shigaraki climbing into bed with Kurogiri after a nightmare about his family.
Don’t think about baby Shigaraki hearing a dog bark and bursting into tears right there in the middle of the sidewalk, so Kurogiri warps them both back home and sits with him on the couch until he can calm down.
Don’t think about baby Shigaraki flinching and wincing around every adult male he interacts with because no matter what his master and Kurogiri say, he knows he’s a bad kid and bad kids get punished and he’s waiting for the first time he steps out of line and gets the belt from either of them.
Don’t think about Kurogiri having Shigaraki help him go through his closet to dig out every single belt he owns and then having Shigaraki disintegrate them to show him that he has power now, and he doesn’t ever have to let anyone hit him again.
Don’t think about Kurogiri raising and caring for Shigaraki as best he can while All For One trains and brainwashes him into his ideal heir and tool. Don’t think about Shigaraki turning from a quiet, clingy child to the angry young man we’re introduced to. Don’t think about Shigaraki getting his memories of his childhood back and, in doing so, recalling how Kurogiri always did right by him, even when he maybe didn’t deserve it.
Especially don’t think about Shigaraki, now armed with the memories of Kurogiri’s love and his own budding feelings for the rest of the League, revving up to break Kurogiri out of prison and get his dad back, get the one good thing about his childhood back in his life again – only to learn Kurogiri is a nomu.
That nothing he did was of his own will or his own decision.
That none of it was real.
