[Jonathan....looks so vulnerable right now. Nagisa hasn't ever really had a normal family, but....siblings are supposed to support one another, right? Support and protect. Now that Jonathan is the one in pain, Nagisa has to do everything he can to return the favor.]

Probably because of the concussion. Hopefully you weren't hit hard enough to completely knock the memory out... [That sounds like much more serious brain damage than they'd be able to treat.] You'll need time to recover, after this.

[He feels the telltale signs. Burning eyes, tightening sinuses. Not yet. Save it for later. For now... Whoever is responsible for this will have to face punishment, but that's never been Nagisa's focus. He's set his sights on something bigger. He'd already told himself he'll need to apologize to Korosensei, right?

He bets he could do it.]

I'm sorry.
