#either that or he didn't want to look at Shigaraki's Nana adjacent face

"All to prepare him to be the next me." This is the only time a "mentor" character says this in BNHA where it is in no way a figure of speech. Looking back on it, it's hysterical that All for One just point blank states his Shigaraki possession goals in his first appearance.

Even All for One's body language is hostile towards Shigaraki here. Frankly, it looks like All for One is about to grab him by the neck and strangle him (which as we have seen in the second war arc, that is one of All for One's go to methods for killing his enemies).

I do wonder if All for One could even remember Yoichi's face at this point. He used Shigaraki as a Yoichi replacement but seeing Shigaraki's face (back when All for One had eyes) probably dispelled the little brother illusion. Perhaps part of the reason he covered Shigaraki's face with a disembodied hand was that after a century or so a hand was all he remembered about Yoichi's appearance anymore.
