Cam sends a clone up to make sure clones can go to space (they can). The satellites are up within a few hours.

Sasuke runs probably unnecessarily exhaustive tests on the video connection and double checks illusions don't carry (look, Minato can cross the continent in trivial amounts of time, it's not like it's that much procrastinating), lets Cam know what's going on, and then sends Tobirama out.

Uchiha Itachi is not, fortunately, hard to track.

Tobirama arrives at one of the old Uchiha hideouts. He recognizes it from the Warring States era. It's been long abandoned. Itachi and another man - Kisame - are before the entrance.

"I come with a message," Tobirama says, simply. (His eyes are closed.)

"Kisame. Let him by," Itachi says. "We'll talk inside."

Itachi's companion grumbles, but steps aside, and Itachi turns to head into the unlit building.

Tobirama follows, eyes still closed. He can sense well enough, even if he perhaps can't interact as well as his brother with natural chakra.

Itachi stops in a large room, and seats himself on a throne. It's a dramatic move he'd been hoping to save for Sasuke - the way the Uchiha banners frame him, and the abstract mural of the Nine Tails behind the throne would've thrown the boy off. Of course, there are many places like this. Itachi can always force Sasuke to face him at another.

"I will hear your message."

"I wasn't the only one brought back with the Impure World Resurrection. Saru told Sasuke what he knows of the Uchiha Massacre."

"Uchiha Itachi, your brother would speak to you."

"Then let him come here."

"No."

"We have another method of communication. You will not be in his presence."

"Do you think that's protection enough? Very well. Let me see this communication method."

Tobirama sets up the video feed and recording as he'd been directed.

And Sasuke appears, leaning against a blank wall. (His sharingan's on, despite his casual posture.)

"Hello, Itachi."

"Hello, little brother."

(He tries to catch Sasuke in an illusion through the video. It doesn't work. Interesting. And, of course, none of his little tries against Senju Tobirama are working...)

"I'm surprised you're not the one here before me."

"This is as much of my attention as you deserve."

"I have questions, Itachi."

"And I suppose you think I have answers."

"You always do."

"That night... You mentioned a third Uchiha. That if I killed someone I loved, and came before you with the Mangekyou Sharingan, there would be three of us alive with such an eye."

"Who is that person?"

(Sasuke has his suspicion, given that Obito apparently attacked the Leaf in secrecy, but he's curious what Itachi thinks is the right answer.)

"Uchiha Madara, one of the founders of the Leaf. I believe your messenger knew him. He was the first to awaken the Mangekyou, and the first to discover its downfall - that to use it would slowly steal its light."

"So you're going blind. Fitting."

"Madara also discovered how to restore his eyes' light."

"He had a younger brother, once, who had awakened the same eyes in the brothers' never ending quest to improve their power. They ruled over the Uchiha together - and as Madara lost his sight, he reached out, and stole his brother's eyes. His light returned, and his Mangekyou became eternal."

"That had been my plan for you, though it seems you still refuse to do as I told you."

"You're fucking insane if you think I'd do anything you asked of me." 

"Perhaps I am."

"What are your other questions, little brother?"

"The Third said you'd bargained with Danzo for my life. That you'd lived as a loyal shinobi of the Leaf."

"I'm curious where the fucking torture fit in there."

"You became stronger for it, did you not? You were weak, without purpose. I gave you an enemy to loathe, a benchmark to overcome, a spark for your fire. And when you faltered, and let yourself be turned aside, I set you back on your path."

"Fuck you."

"I'm not going to kill you. I'm not going to kill anyone, least of all to get the fucking Mangekyou. Rot in obscurity, for all I fucking care."

"I do love you, Sasuke, despite all this. You're my little brother."
