"It's Okay Neji your clans next to be massacred and it will probably be your fault." Naruto says
"What?!" Neji shouts.
"I mean...Uzumaki, Senju, Uchiha..." gestures to Neji "Your clans the next massacre. It has to be. It's fate Neji. Your clans gonna die and your probably gonna cause it."
"No! No! The Hyuga is the largest clan in the village!" Neji says.
"So was the Senju at one point till the Uchiha took them out. Then the Uchiha got massacre by an angry prodigy who attacked his family, scared his sibling and became a missing nin...sound familiar?" Naruto asked.
Neji stands there panting and passes out from a panic attack at this and Orchimaru gets the idea to remove Neji's Seal and put a curse mark on him.
For context of this Naruto was taking the words from Kurama because Jiraiya told him use the Fox and Kurama agreed but you gotta fight like a Fox.
