A half-wit, Deidara-senpai had called him once. Tobi hadn't taken offense. Tobi never took offense.
As far as he was concerned he was complete in wit, there was nothing that he felt was missing. Nothing that he needed anyway. A few fuzzy memories and blurry faces with names he couldn't recall were of no importance to him now.
The only thing that was half, as far as he was concerned, was his vision. Not that it mattered, of course, because several excellent ninja got by with only one eye. Deidara-senpai for one.
Even so, sometimes Tobi wondered what had happened to his left.
