Sometimes, Obito has bad days. It 's the type of day where he wakes up and he wants to claw his own eyes out.

Or one of his eye, the other eye? He doesn 't know where the hell it came from. An Uchiha, sure, but which? Whose eye was it? What was the name of its owner? Their age? Their appearance? What kind of life did they lead? What were their last thoughts before their fellow clansmen killed them?

Obito doesn 't know; they 're dead. The dead don 't speak and they definitely don 't speak to their killer.

Obito wakes up sometimes and he remembers that he only has one true eye inside his socket, the other eye? He has no idea who it once belonged to, but he sure as hell knows it wasn 't entrusted to him.
