[He listened... and when Madoka's head bowed, he stretched out an arm and pulled her in close to his side. He understood why she'd taken him aside now, and understood her concerns.]

Then we'll have to do what we can to stop that happening.

... I know Katsuya was saying something about Mami earlier. I'm guessing this is what he meant. And that's fine.

[But he really wished this was more commonly known. He'd bet there were a dozen people on the train right now who could help in a more permanent way if they'd had a clue. But he couldn't break Madoka's trust, or reveal a secret about Mami that she didn't know herself. So all he could do was gently, soothingly, rub Madoka's arm.]

We'll keep her safe from that. And thanks for letting me know, Princess.
