Tobi and Sasuke in “Unfinished Business”

You think you know all about your older brother but you know nothing.

Sasuke

If you continue spouting such nonsense and lies, I'll kill you right here.

You're not making this easy. I suppose that's only natural hearing this from a complete stranger, but what I'm telling you is the truth. Itachi did mention it, didn't he? That he wasn't alone that night, that he had an accomplice. I am Madara Uchiha. I know everything there is to know about Itachi. I suppose Itachi died without realizing that.

Sasuke

Shut up! None of that matters anymore! Just get out of my sight, you hear me?

No, you listen. You need to hear this. It's your obligation. It's about the life of your brother who risked everything for the sake of the shinobi world, the Hidden Leaf Village, and most of all for you, his little brother. You will know how Itachi Uchiha lived.
