He’s what the fandom thinks Part 1 Sasuke is, an insufferable brat who is so hooked on what happened to him, he projects that insecurity to everyone around him (Obito more than anyone).
Post-Konoha crush arc he meets with Yugao at the memorial stone and says he stands in front of it every day for hours?
It takes a back seat in Shippuden but every time he’s late in part 1 it’s because he’s sitting at the memorial lol. He’s just as emo as Sasuke but without anyone to lash out at
