It doesn't sound like Hawks is talking about Endeavor because Katsuki already knows more than he wants to about the Todoroki family. Enough to know what he needs to know. For a family that kept so much secret for so many years, they really let that all hang out in the last year. Talking about it in front of other people. Playing it on the news. Admittedly the whole country fell apart shortly after that, so people have other problems to focus on, but Todoroki always waited, made sure not to be too observed coming and going from UA. So people wouldn't be upset about him.

"Maybe not this exact moment," Katsuki says, "but the whole world's changing. People ought to know and to deal with them with that change. It's the best time to change anything. That includes them."

"So if they've been getting away with terrible things, someone who doesn't already know needs to know. Someone who will do something. Who can."
