Well, there's a pouting child with a familiar face half visible through one of those windows, shoulders hunched up around his ears as he stares moodily at the night.

Yeah. That looks good. She climbs up the wall and taps on the glass.

He startles.

But after a moment he opens the window, cautiously.

"Don't shout, okay," she says, then drops the camouflage.

He nods, slowly.

"Who are you?"

Well, there goes that vague hope. Poof.

"My name's Elieyha. I'm from the future. And Suna. Can I come in?"

"...Sure," he says, sounding a bit skeptical.

She clambers through, lithe as any ninja. Her clothes support her assertion that she's from Suna, at least, loosely draped and not at all in the Fire style. She has a jar of sand strapped to her back, and looks to be about the same age as Sasuke.

"How are you from the future? Why find me?"

"It's kind of a long story." She finds a likely-looking clear spot on the floor and sits down. "But I met you- or I guess a version of you, a little less than ten years from now, during the chunin exams. Lots of stuff happened and I wound up moving to Konoha because I didn't like being in Suna. We were roommates. Then one day I woke up and I was back in Suna and also in my younger body. So I left again."

"Huh. What about my sister?" He guesses he can imagine moving out of his parents' house and getting a foreign roommate, but Hisame'd probably follow him. Just. Knowing her.

"...You didn't have a sister."

"I do right now. Why wouldn't I then?"

"I don't know. Everything else has been the same."

"Maybe I just wasn't talking about my family," he says, slowly.

...how much of this does she want to into right now? None.

"Maybe."

"Did you want to stay with me again or something then?"

"That was the gist of my plan." Insofar as she had one.

"...I'm not going to be able to hide you from my family, I don't think." And he shouldn't, anyways, even if a secret is a tempting idea. "And they'd tell the Hokage. Maybe."

"This is the Third? I don't know him as well as the next one. I can tell them about Suna. If your family would be on my side, them knowing would be better."

"I don't know if they would be." He furrows his brow. "My sister would. I could probably get my brother to help, too, but he'd be more likely to tell the Hokage."

"The Hokage will be told eventually. I just want it to be at least a bit controlled."

He nods. "I can maybe get my family to do that. They don't always like the Hokage."

She nods. "Probably in the morning."

"I can hide you until then from everyone other than my sister."
