This is Remus talking to Moony in his head

This is Moony talking back

I Have to Do It

"I have to do it, Remus!" Harry argued, standing up from his seat by the fire.

"Harry, for the last time, Sirius is dead."

"He is not dead!"

Remus hung his head, "Harry, Sirius died, there is no changing that."

"He is not dead," Harry said again.

"Where is the proof of that?"

Harry brandished the strange book he was holding, "In here."

Remus shook his head, "Harry, no one has been able to read Parseltongue in hundreds of years."

"Until me."

Remus shook his head again, "Explain your theory to me again."

"It is not just a theory. I read it in this book, this book written by the creator of the Black Veil."

"Okay, just tell me."

Harry turned to the marked page and began reading, "The Black Veil's true purpose is to relive your life, The life you would remember if you had a soul. Those who pass through the Veil with their soul will be caught in Limbo, neither Heaven or Hell. Dead to the world, but breathing…"

Remus cut-in, "What does it mean 'dead to the world'?"

Harry waved his hand, "It means the world will see them as dead."

Remus sighed, he was just getting over the grief, why open up those wounds again? "What is Limbo?"

Harry rifled through the pages, "Limbo is an in-between-place, where you live your life over, as an observer, unable to fix mistakes, and noticing them more clearly."

Remus stared at the book, "So it's torture?"

Harry carefully watched Remus's reaction, "For some."

"For Sirius?"

"Perhaps."

"Can you leave Limbo?"

"Not without help."

Remus faced defeat.

Do it!

Moony? Why are you always bothering me?

Because you never talk to me.

Can you blame me? One night a month you make my life a living Hell.

(whimper) That isn't my fault!

Ha, ha, you're a great actor, Moony, must have picked that up from me.

Sure I did.

Why do you care, anyway? I thought you liked to see me miserable?

Remus, you should not talk like you're the only victim here. I lost a friend too. Besides, Harry is a brother wolf.

But, he…

He did defeat the man that sent shivers down my spine, alone, didn't he?

Fine, fine, I'll help.

Remus rubbed his forehead, "What do you need me to do?"

Harry smiled, all those nights of hanging around with Moony finally paid off, "Cover for me while I'm gone, if I'm not back in a week expect the worst. I'm leaving you and the Weasleys my money, and I want a small funeral, no press."

Harry smiled as he stepped into the fire place, "I'll bring him back, Remus."
