Sorry. I'm so sorry. This is a one-shot based on what happens in chapter 691. If you do not like horribly horrible spoilers, DO NOT READ.
I'll just...I'll just close my eyes and sleep, but this man is talking to me... Madara stared at the man, Hashirama, with small slits for eyes to see through the already foggy atmosphere about the world. He was weak and couldn't feel anything, yet seconds ago he was strong.
He could feel everything.
He wouldn't be laying here and dying if it weren't for the cruel twist of fates that crept upon him so suddenly, just a heart attack in the process of ending another life. The man he could barely make out was still talking, garbled sounds of water sloshing in one ear and making its way quickly out the other, every once in a while sounding out "Madara...comrade...friend..." A soft bit of wetness scorched across his thin face after the last of his words he could barely hear.
Why was he crying?
Who was he?
"Hashi...rama..." came a gurgled sound from the throat of the weaker man. The Senju's eyes turned to Uchiha black and dull ones, ones that represented the fate of a man that could be foretold centuries before his birth. "Madara," strained the other as he leaned even closer to his dying friend. Something was exchanged from Hashirama's mouth, something about comrades. "Comrades...huh..." A choked gasp escaped the dying man's mouth as he felt his heart slowly pause, start up again, pause...pause...pause...ba-bump. "Well...if that's...how...it is...I...won't..." ba-bump...pause...pause...
Izuna do you remember me?
Do you remember your nii-san?
I'm coming to see you...
If you understood my pain, would you understand why I did what I did? Would it still remain an illusion to you, an illusion from my eyes?
Madara awoke on the ground he had died upon, sitting upright, looking around as if he had never died at all. Hashirama was still there, standing now over his body like a hungry vulture awaiting the bones of an animal to pick dry. "Am I dead?" asked the confused Madara, who now felt much stronger than he was before. "We all are," replied Hashirama in a dazed voice. The Senju looked far away as if he was experiencing a second pain he never wanted to know again.
The previous Hokages stood beside Hashirama, making sure the man was alright as his normally cheery face formed a frown of distress towards open air. Madara let a sigh out as he wrapped his arms around the male in a loving way, missing the friendly bond he once shared with the Senju he should've never met with before.
And he saw him. Standing there with raven hair as plain as day, waiting for a turn to see the new arrival. "Zuzu...?" asked Madara as tears formed, silently willing themselves down the fronts of his cheeks and lacing his skin with a warm and bright feeling. "You never came, Mada," the young boy said as he inched his way closer to his brother. "I saw you die but you never came."
"I found it hard to come to you after you left me so cruelly..." And the brothers embraced with such passion and love that they never wanted to leave each other again. "I never left you," said Izuna.
"I was there when you died at Hashirama's feet."
"I was there when you took your own life and gave it to the young Uchiha."
"I saw you suffer all those years over my doing, Madara."
"And I regret ever leaving your side."
If you could see through my blind eyes,
If you could whisper in my deaf ears,
If you built a wall to block the lies,
If you built a dam over my tears.
If you walked a million miles,
in the shoes I wore today,
where were you when I needed you,
those million miles away?
This is my interpretation of what I think happened to Madara and Izuna after they both died. The poem at the end was by me.
