No, that's silly. She's just talking about Sable's experiences.

…And Sable is… trans… right?

…So she's describing the experiences of someone who's trans…

…

…Fuck.

"…Dang, hey—sorry to butt out in the middle of a conversation, but I really gotta take a leak! See you guys after lunch?"

Not waiting for his(?) friends to respond, he(?) hops off of the branch he(??) was sitting on and hurries into the academy building—all the while doing an admirable job at keeping himself(!???) from hyperventilating.

Hinata stares concernedly at his(?) back.

{Direct hit. Eggshell cracked. She'll figure the rest out herself and come asking us questions soon. Maybe take advantage of her absence to scheme nutrition with Hinata?}

{Oh, good idea!}

"I hope he's ok…

…

…Do you think he'll be alright? He didn't finish his lunch—and it doesn't look like he's eating enough normally…"

"I h-hope so too."

Oh, she wasn't imagining it, Sakura's concerned about Naruto-sama's diet too.

"N-no, I don't think he is. And the v-village seems to treat him poorly."

Oh, she was going to ask about that!

"Right, I was wondering about that yesterday, actually: do you have any idea why the village is like that to him? I never really thought about it, but a lot of the people here just treat him… worse than everybody else."

Hinata knows what grudge the village is holding against Naruto. She's seen the intricate lines of chakra on Naruto's body, binding that dangerous passenger.

She knows Naruto isn't at fault for the harms they suffered, no matter what the village thinks.

The question is: can she trust Sakura with this information? It's a dangerous secret, one the rest of the village shouldn't know.

Sakura's shown more concern for Naruto-sama in one day than anyone but Hinata has in years.

Sakura also trusted them both with the secret of her own passenger.

And it's not like Naruto-Sama's secret is particularly well-kept.

Still, she should be careful how she phrases it.

"Th-they hold a grudge for a disaster that happened when he was an infant," she whispers.

…Huh.

Ok, she's not sure what she was expecting, but that definitely wasn't it.

Holding a grudge against an infant sounds bizzarre, but with how Hinata's whispering, it doesn't sound like a weird superstition or anything.

Sakura lowers her voice.

"…What did happen when he was an infant?"

How does she say this indirectly enough, while still making sure Sakura figures it out?

Ah.

"W-what danger must be sealed inside a p-person?"

…Sealed inside a person?

Maybe some kind of possession technique, or chakra beast, or…

…A Biju?

Wait, is she talking about the fucking Kyubi attack!?

Sable realizes that Hinata's being very careful with her words, trying to avoid saying it outright. Presumably it's classified. 

So she works the problem. She rifles through Sakura's memory to understand what a Biju is, and how it must be sealed, and what Sakura knows about the attack. Assuming every word is deliberate, then the Nine-Tailed Fox, the Kyubi, a sapient mass of chakra presumed to be hateful, broke free from its previous host when Naruto was an infant, then vanished again, and must be sealed inside a person for safekeeping.

And everyone's holding a grudge against Naruto.

And then the realization clicks.

Sable burns with rage and protective indignation.

{Is she telling us,} it growls, {that this village sealed a terrifying sapient superweapon inside of a child, and then did not go to the trouble of making sure the child would be treated well!? And the villagers are being allowed to take out their grudge against the Kyubi on the person standing between them and it!?}

This is not a happy symbiote.

Wait, right, Hinata's implying that he's a jinchuuriki!

This… isn't like what she's read about at all. Jinchuuriki are important—they're cared for, not practically left to starve!

Her expression turns sour, and she glares around the courtyard before returning to face Hinata.

"You're telling—"

She stops herself and lowers her voice.

"You're telling me the villagers know about this, and that's why they're treating him like that!?"

Yes, telling Sakura was the right choice.

Hinata's expression is small and sharp, and not quite what one would call a smile.

"A-as best I can tell, yes. I can read lips. One mentioned it just after he left."

Right. That settles it: they're doing something about this. She's not sure what, but this is unacceptable.

"This is not ok."

"…We can't change how most of the village treats him, but we can make sure he's treated acceptably—by doing it ourselves.

I was already thinking about talking to my mom about packing an extra lunch for Naruto, and we're gonna be training together, but is there anything else we can do? I didn't really interact with him much before, so I'm probably missing things."

"Food and friendship are the biggest things. Most people shun and isolate him, and his groceries always seem to be fewer and lower quality. I th-think maybe shops are overcharging him and only giving him their worst goods."
