There is only one person that Shikako has ever honestly considered telling the truth about her past, but so long as he wears the Hokage’s hat she cannot:
Kakashi is the Rokudaime, an honor and responsibility that he never wanted but must dutifully serve until his successor is deemed ready. So long as he is the Hokage he cannot put his students’ lives above the rest of the village.
And so she does not tell him, even when her knowledge has stopped being relevant, even after all of the things she feared has been resolved and become the past twice over. She does not tell anyone.
Not until he passes down the hat.

Naruto, finally accepted by the village he calls home, stays and learns. Sasuke, chafing under the years of being protected with a short leash, requests missions with long durations in far off places.
Shikako chooses to wander the land–training trip or research trip or maybe even both, inheriting Jiraiya’s role as spymaster and fuinjutsu master and author (though her books are far less perverted in nature).
During war, Team Seven banded together to save the world. In peace, they spiral apart.
Perhaps one day they will be reunited, but there is very little that can stand up to one of them, much less requires all three, and so that day is far away.
—
There are marriages and children and entire lives being lived without her, and Shikako realizes, almost five months after her twentieth birthday, that this is basically the same thing that must have happened after whatever ripped her from her old world reincarnated her in this world.
Maybe her sister got married, maybe there is a niece or nephew in that old world that she has never met and will never meet. Or has time progressed even further–another generation on who wouldn’t even be told of their missing great aunt, much less care.
She doesn’t know if there’s a niece and nephew here, in this version of this world, that she hasn’t yet met.
She goes home immediately.

She regrets it almost immediately.
She’s grown beyond the shape she once carved herself into for their sakes, and now they no longer fit.
She doesn’t know if she means her brother, her team, or Konoha itself.
It’s stifling and bewildering, this place she once called home, this place she killed and died for. All of the changes like unfamiliar scars on people who she once would have said she knew better than anyone.
That is no longer the case.
Shikamaru has long since learned to be less protective of her–his twin his shadow his sister–but now he has a wife and child and somehow Shikako is no longer his. Sasuke has settled into his own skin, an identity she has never seen, a life she could have never predicted. Naruto is the hero grown, triumphant, successful; he does not need her to guide the way, to show him how to make dreams reality.
He’s already done so.
Naruto is no longer a boy hoping to be the Hokage.
He is the Hokage.
Which means Kakashi is not.
Once, he may have been the only person she ever considered telling the truth, but that was many years ago.
She has changed and so, too, has he.

A/N: … I’m posting this as a response to this prompt because this is what shook out of my brain, but I’m not entirely satisfied with this so I will hopefully be making a less bleak/rambling edition
