Obito stares open-mouthed at fully-revived, rinnegan bearing Madara Uchiha. How is this possible?
"Hashirama!" grins Madara. "How is our village doing?"
"Oh, it's great," says Hashirama, the smile on his face turning to one of pride. "We're up to the Fifth Hokage: Fugaku Uchiha!"
"Yo," says Lord Fugaku, raising a hand in greeting.
"That's Madara Uchiha?" Sasuke whispers to Naruto. "We pulled down Madara Uchiha's pants?!"
"Yes you did, little girl," says Madara, apparently having heard Sasuke. "And I will-"
"HEY!" Yells Obito, noticing something strange. "Aren't you supposed to be dead?"
All of Madara's attention turns away from Naruto and Sasuke, only to zoom in on Obito. "Why aren't you following our plan? I saved your life and you didn't even do what I asked of you in return. Explain, now."
"Um…" Obito panics. "Sorry?"
"Don't apologise!" snaps Madara, glowering angrily at Obito. "Tell me what happened!"
Rin puts her hand on Obito's arm. "Start when you gave Kakashi your sharingan," she says softly. "So that the people here have some context."
"Okay," says Obito, forcing himself to calm down. He takes a deep breath, fixes a point of time in his mind and does the hand signs. "Flashback no jutsu!"
The world turns white for a second before taking Obito and everyone else back many years to a large tree outside a cave.
Young Obito looks down at the cave from his perch in the tree. Birds chirp nearby, signalling that they are not bothered by his presence. Obito pulls out a kunai and says, "Time to go." He is the picture of determination.
"Go where?" asks a Stone ninja, appearing behind Obito.
Obito turns in shock, just as Kakashi appears and slices the Stone ninja across the chest. The Stone ninja falls back, and comes to land on a nearby branch. The two Leaf ninjas and the Stone ninja stare at each other for a few seconds.
"That silver hair and white chakra blade…" the Stane ninja says, disbelief evident in his voice. "Could you be the White Fang of the Leaf?"
"No," says Kakashi, irritation evident in his voice. "He's dead, dumbass."
The Stone ninja thinks about this for a second. "Oh, you're his brat. That makes more sense." The ninja grins. "Well, I guess I have nothing to be afraid of."
"Aw, you were so cute when you were a kid, Kakashi sensei!" says Naruto, interrupting the flashback.
"I was also an asshole," says Kakashi rubbing the back of his head in embarrassment.
"Yes you were," says Rin, grinning.
"Hey!" snaps Tenzou, glaring at Rin. "He's still an asshole. But he's MY asshole, so you can all shut it."
"Yep," nods Naruto, crossing his arms. "He reads boring porn when he's supposed to be training us."
Sasuke hits Naruto. "Make Out Paradise is NOT boring."
"Sasuke, you know you're not allowed to read that smut," sighs Lord Fugaku.
"Back to the flashback, please," says Madara. "I don't have all day."
"Yes, Madara," says Obito, and unpauses the flashback.
The Stone ninja uses the camouflage jutsu to vanish from sight.
"I can't smell him or sense his chakra," says young Kakashi. "Stay on your guard while I locate him the hard way." Then Kakashi stiffens. "Behind you!" he moves to attack the Stone ninja, who appears behind Obito, only to be slashed across the face.
The Stone ninja leaps away as Kakashi falls backwards, clutching his face in pain.
Obito starts to cry.
"I'm not dead yet," says Kakashi sternly. "Don't lower your guard."
Obito raises his goggles and wipes his eyes on his sleeve. His face sets in determination and he stands, a kunai in his hands. "DIE!" snaps Obito, as he turns and stabs the Stone ninja right as the enemy is about to attack.
"What's with your eyes?" asks the stone ninja, staring in horror at the glaring red sharingan in Obito's eyes.
"I will protect my comrades," says Obito firmly as the Stone ninja falls dead.
"Obito, your eyes…" says Kakashi, staring.
Obito stares down at his hands in astonishment. "Yeah… I think this is the sharingan. I can see the flow of chakra…"
"Cool," interrupts Kakashi. "We need to bandage my eye and hurry up and save Rin."
"Oh, right!" agrees Obito. Quickly, he helps Kakashi bandage his eye and the two boys head down to the cave to rescue their teammate.
"So were you two on a rescue mission or…" interrupts one of the Order of Steve.
"Nah, we abandoned our mission to rescue Rin," says Obito. "Rin got captured and I was like: f*** the mission, let's save Rin! And Kakashi was like: But… and I was like: Your Dad was a legit badass, let's do what he did. People who abandon their comrades are worse than scum."
Sakumo Hatake looks confused, but flattered.
"Ahem." Madara clears his throat.
"Ah!" yelps Obito. "Sorry!" He unpauses the flashback.
Kakashi and Obito enter the cave, where a second Stone ninja has Rin tied up.
"Her chakra is all disturbed," says Obito, as if he discovered something of great importance.
"She's under a genjutsu," says Kakashi, as if that much was obvious.
The Stone ninja grins, draws out two blades attached to his wrists and runs forward to attack Obito and Kakashi. Using his new sharingan to speed up his movements, Obito leans back and, using his hands to propel himself into the air, he plants his feet on the Stone ninjas forearms, stopping his attack. As Obito does this, Kakashi leaps over his head and slices the Stone ninja across the back, knocking him down.
Without bothering to check if the Stone ninja is dead or unconscious, Obito and Kakashi run over to Rin. Obito cuts her free while Kakashi releases the genjutsu.
The Stone ninja gets up saying, "That was a nice combination, but you're just a bunch of brats." He slams his hand onto the ground and yells, "Earth Style: Stone Collapse!"
The cave begins to shake and small rocks begin to break free from the ceiling.
"RUN!" Orders Kakashi, and the three Leaf ninjas run for the exit. A rock hits Kakashi on his blind side, knocking him to the ground.
Obito runs back and picks up Kakashi, who looks stunned. The roof begins to fall on them. Obito tosses Kakashi to safety just before the boulders falling from the cave ceiling hit the ground. When the dust clears, Rin and Kakashi are safe but Obito lies, half crushed, beneath a boulder.
Kakashi scrambles over to Obito and tries to push the boulder off him. The boulder refuses to budge.
"It's okay, Kakashi," says Obito, smiling. "It doesn't look like I'm going to make it."
"I should've listened to you from the start!" cries Kakashi, beating his fist against the ground.
Rin sits in the dirt dejectedly and cries.
"I don't deserve to be a captain," Kakashi whines. "Or a jounin."
"Oh," says Obito, as if he just remembered something important. "That's right. I forgot to get you a present for becoming a jounin. I know… I'll give you this sharingan."
Rin gasps and Kakashi's eyes widen.
"Rin," says Obito. "Please use your medical ninjutsu to transplant my sharingan into Kakashi's wounded eye. I'm going to die," he says addressing Kakashi again. "But I will become your eye and see the future."
Once the transplant is completed, Kakashi explodes a hole in the top of the collapsed cavern. Even though the onlookers could have seen what Kakashi was doing, anything outside Obito's line of sight is a field of white. They hear, rather than see the Stone ninja say, "You're just a kid, after all. What's a shinobi doing crying?"
And Kakashi is crying, but only from Obito's sharingan.
"Kakashi, protect Rin," says Obito.
"Yeah," agrees Kakashi, drawing his chakra blade. Kakashi leaps forward, out of their line of sight. They hear the sound of metal on metal followed by the sound of a blade shattering. And then they see a brilliant white light accompanied by a sound like a thousand birds chirping. The stone ninja reappears over the edge of the mound of rocks, and falls dead. Kakashi leans over the edge, panting for breath.
"Enemy reinforcements are coming," says Obito, and pulls his hand out of Rin's grasp. "Go."
Kakashi's eyes widen in panic as he senses something the onlookers cannot see. "Rin! Hurry, take my hand!" He holds out his hand for her. She turns away from Obito and grabs Kakashi's hand. The rocks surrounding Obito collapse in on him, and the memory fades into darkness.
"So did you die or not?" asks Naruto, screwing up his face. "That part is really unclear. I mean, you just got crushed, but you're right here, alive. What happened next, dattebayo?"
"Be patient," says Obito. "There is more."
