For people who think it's Shisui here's two things wrong. One, Shisui was killed pure and simple and had no Sharingan to make it so he can use Izanagi to come back. Shisui committed suicide and last I heard he was died for decades so how can he not forgive Sasuke or Naruto for killing Itachi. Hell how can he know they killed them?

Two, Shisui knew what he was doing and had no regrets, and trusted Itachi with what he needed to do even if it ended with him dying.

More likely than not the two of them are experiments, or experimented on Uchicha blood, and have goals that we don't know about.
