Before the real Madara Uchiha appeared, the Uchiha Clan had always speculated about Obito's identity.
Some believed that Madara Uchiha might truly have survived until now.
Others believed that some lucky person had obtained the Uchiha Clan's Sharingan and was impersonating Madara Uchiha to cause trouble everywhere.
Of course, some also believed that he might be an Uchiha bloodline left wandering outside the clan, unable to return and therefore harboring hatred toward the Uchiha Clan!
Most members of the Uchiha Clan subscribed to one of those three guesses.
And of the three, the third was considered the most likely by the Uchiha Clan!
Even Sasuke had leaned toward either the first or third possibility.
But today, Kakashi told him that the real identity of the fake Madara Uchiha before them was actually Obito Uchiha, the man who had supposedly died as the "Sharingan Hero"!
It dealt a considerable blow to Sasuke's worldview.
After all, not a single member of the Uchiha Clan had ever guessed that Obito was the Uchiha who had once sacrificed himself for Konoha!
After all, bringing the dead back to life was simply too unbelievable.
Even Hashirama Senju and Madara Uchiha could only appear now in Edo Tensei bodies, let alone anyone else.
So there was only one answer.
Obito Uchiha had not died during the Battle of Kannabi Bridge. For some reason none of them knew, he had merely chosen to fake his death.
After that, for reasons unknown, he had begun to hate Konoha and the Uchiha Clan, which led to the Nine-Tails Attack and the Night of the Coup.
There was simply too much to take in. Sasuke felt that he needed a moment.
He did not even have the energy to dwell on why Kakashi had continued to hide Obito Uchiha's identity
