Shisui stood alongside the Hokage and his council as the suspected (most likely the actual) Niidaime Hokage underwent the Yamanaka scan by Inoichi Yamanaka, who had been specially called back on duty despite being retired from T and I. The caution was necessary, of course. It wasn't everyday that you had someone claim to be Tobirama Senju and be almost actually be believed.

The Hokage had told Shisui that he was sure that this was the real Niidaime and the mind scan was just a formality. He told him that just before asking him to be the guide to the time displaced Hokage to the modern Konoha.

"Tobirama-sensei is very picky with people. I doubt he wouldn't accept anybody else." The Sandaime explained.

"But why would he pick me? He doesn't even know me." Shisui calmly questioned. No, he didn't whine. Uchiha don't whine.

"He knew your grandfather. You resemble him quite a lot, and not just in looks. Oh, look they are done." Sure, enough Inoichi-san was leaving the room to give his report.

"He is Tobirama Senju, Niidaime Hokage." He announced.

"I told you." Sandaime-sama chortled. "Go on, Shisui. You don't want to keep him waiting."

Ever the dutiful shinobi, Shisui entered the Interrogation room. He wasn't nervous. Uchihas didn't get nervous.

He knew from experience that a Yamanaka scan left the victim disoriented for a while. He patiently waited for Niidaime-sama to reorient himself to his surroundings.

It didn't take much time. Soon enough, he was at the recieving end of a stare from two non-sharingan red eyes.

"You're Kagami's grandson." The Second Hokage said.

He didn't think it was meant to be a question but rushed to answer. "Hai, Niidaime-sama."

His reply was met with a frown. "I'm no longer Hokage. I've given away my hat."

"Hai, Niidaime-sa.....I mean, what should I called you?"

The former Hokage raised an eyebrow at that. "Tobirama."

Ah, one word answers, social inadequacy, genius, he was like Itachi, wasn't he? Shisui could do this. He already had experience with it.

"Would you like to go to the library?" Itachi always goes to books on the rare occasions when he doesn't know something. Perhaps Tobirama-sama would also like to fill his gaps in knowledge from books rather that asking questions and reveal his ignorance.

"That would be acceptable." He answered.

In the end the day didn't turn out as bad as he initially feared. Tobirama-sama was definitely not impressed with much of the history of Konoha after his supposed death. The second and the third shinobi wars, destruction of Uzushio, the Kyuubi attack, the Hyuuga incident....the list went on. Oh, he didn't say anything. It was just the way his mouth would twist whenever Shisui clarified a point which was glossed over by the history books, because of white washing and propaganda.

No, the real kicker didn't come until the end of the day, when Shisui was taking the former Hokage to Yakiniku Q. There was a huge crowd gathered in front of the restaurant and the owner was shouting at a little boy whom Shisui recognised to be the Kyuubi jinchiruchi. This wasn't going to end well.

"I didn't steal anything. I gave you money." The kid was shouting, trying to put on a brave face despite the tears and snot on his face.

"Be quite, brat. As if I would sell anything to a monster." The owner snapped, raising his hand to hit the young boy, when it was stopped by non other than the Second Hokage.

"What is going on here?" He asked, in a dangerous voice.
