Thinking about how the very last thing kakashi did for Rin was hug her. How much sheer blinding grief went into that hug, and the overwhelming regret.

Like what do you do? You're a kid. You've been kind of a standoff-ish jerk but you've been better lately, but still keeping people at arm's length. You're friend, and teammate, someone you've sworn to protect, has just committed suicide by your hand for reasons you dont really fully know yet and you're just a child. A 12 year old kid.

So he hugs her. It's probably the only hug he's ever given her, and it's the last hug he'll ever give her. It's probably the 1st hug he's willingly given anyone since he was 4.

It was the closest he could get to an apology in that moment or the closest to any semblance of comfort.

And it was absolutely a hug. He tucks his head against her's. It's all he can do.
