Someone online, on some website somewhere wrote this:
Part of the Naruto/Obito chat that was left out.
Obito: Naruto you know why I'm evil right? My girlfriend died and I went apeshit after that.
Naruto: She wasn't your girlfriend. I saw in your memories that she liked Kakashi Sensei.
Obito(angry): I hope Sasuke f*cks the shit out of that red head over there.
