I was reading some old chapters, when this idea came to my mind.
You guys all know Hayate Gekko, one of Konoha's special Jonins and Yugao Uzuki's lover .
When Kabuto summoned his undead army, an unknown guy was standing next to Neji's father.
His head band looks like Hayate's, and he was heading in the same direction as his former friends. However, when they rechead the first division's location, he wasn't with them.
So the questions are : Is it him, and where is he?. Did Kishi forgot him?.
Feel free to discuss. :D
