"Hand over the Mangekyō Sharingan?" Fugaku's gaze sharpened, then he let out a cold laugh. "Hmph, so the village really is coveting our Uchiha Clan's Mangekyō Sharingan. Even if I destroy my eyes, I won't hand them over to them!"
Itachi hurriedly explained, "Father, you misunderstand! You don't need to turn your Mangekyō Sharingan over to the village. I'll keep them in secret, and we can claim publicly that they were taken by the God Organization."
Hyuga Kagami and Itachi had discussed what to do with Fugaku's Mangekyō Sharingan.
If Sasuke could awaken the Mangekyō Sharingan in the future, then the three of them—father and sons—would possess three pairs of blood-related Mangekyō Sharingan that could be fused with one another.
That meant that, if one of them made a sacrifice, the three of them could fuse a legitimate pair of Eternal Mangekyō Sharingan.
In the original timeline, Fugaku's pair of Mangekyō Sharingan had disappeared after the night of the Uchiha Clan massacre. Thus, Itachi had offered up his own Mangekyō Sharingan, allowing Sasuke to obtain the Eternal Mangekyō Sharingan.
Now that Fugaku was the ringleader behind the Uchiha Clan's rebellion, he naturally had to be punished after its failure. Having him offer up his Mangekyō Sharingan would not only placate the Hokage faction in the village, but also prepare for the future fusion of the Eternal Mangekyō Sharingan.
As for whether they would be fused into Itachi or Sasuke, Hyuga Kagami had yet to make a decision.
However, considering that Sasuke was the reincarnation of Indra Ōtsutsuki and possessed Indra Ōtsutsuki's ultimate Yin Release chakra, his chances of evolving the Rinnegan far exceeded those of ordinary people. Uchiha Madara, the previous reincarnation of Indra Ōtsutsuki, was the best example. From that perspective, having Sasuke fuse the Eternal Mangekyō Sharingan would
