Heart to heart

As Harry finished with his explanation of what they where going to do he grabbed Sirius and apparated to the old Black townhouse scaring the jeepes out of Sirius

"What are we doing in my old house pup?"

"Well first we are going to get you all healed and cleaned up, and your brother left something from the dork lord to Kreacher to destroy. Also I'll put the house under Fidelius so we'll be resting for a while here."

As they enter the house "What is blood-traitor and tiny old monster doing here?" the little nutter appears with a pop and questions both of them.

As Sirius was about to berate the thing, Harry was a step closer and says "This is the house of Lord Black, you will respect him as is deserved and we will be living here for the foreseeable future, so unless you want clothes and be a free on the streets you will behave like a true elf of House Black should! Apart from that I personally came to destroy the locket your previous Master Regulus gave you, so you should be thankful, understand?!"

Kreacher started with a scowl then started moving his head up and down agreeing with everything Harry said by the time he got to the clothes but then started jumping like crazy and with a weird and freaky smile at the part of the locked "Oh yes, little Master. Kreacher was wrong. Shall Kreacher prepare a bath for the nasty dog? Something to eat?"

"Yes to both Kreacher" said Harry making him dissapear

Sirius had his mouth open that it almost let a car pass in there at the exchange between Harry and the elf. "He just needed tough love, and the promise to complete the last order your brother gave him."

"Wow pup, that was... Merlin!! I can't even begin to explain. You are going to have to start telling me things or I'm going to have a heart attack. What did my brother have him do against the Dark Lord?"

"Well your brother found out Lord Moldyshorts made a Horcrux and went to get it so he could destroy it, thing is he couldn't get out from where it was so he called Kreacher to take it and destroy it. Kreacher couldn't do it so he is going more crazy by the day by 1) not being able to complete his last master's order and 2) the nasty dark magic of the locket. If I'm not mistaken he was wearing it as a form of punishment."

"Merliin, my brother tried to off the dark lord" Sirius collapsed against a wall

"Go get a bath padfoot and then come to eat something"

Sirius nods and walks up the stairs absentmindedly to get a much needed shower. "Kreacher, I need you to show me where the ward stone is"

The elf pops and guides Harry towards the Ward Stone Harry tells him that when Sirius is back, he will destroy the locket so as Sirius can watch his brother Regulus noble sacrifice in destroying a part of the dark lord soul, making the little thing more happy at calling Regulus noble.

Harry spent the next 15-20 minutes casting the Fidelius with an immortal untouchable secret keeper, the most broken part is that he thought it wouldn't work, but it did and it was amazing! He summoned the spirit of Murasama, the Zanpakuto, and made him the secret keeper. Harry just stood there contemplating what other things he could do with this knowledge until he heard Sirius scream and fall. He started running upstairs where he found Sirius looking up everywhere and started laughing until his stomach hurt and told Murasama to tell him the secret.

Sirius was until the moment the Fidelius went up was on the shower singing and washing himself when everything went dark, he could hear the shower running and knew he was taking a bath a second ago but then forgot where started panicking then started hearing laughter until he heard the secret and remember the Fidelius. He went Super Saiyan (ehmm cough wrong story). He changed to his animagus form and jumped at Harry making him fall on his back and shook all the water while liking his face.

"Gerofff mangy mutt! Or I'll neuter you!" that left the dog walking back and whining. "Change into some clothes and come downstairs to eat something"

After eating a nice lunch they spent a few hours with Harry explaining the things Dumbledore did to Harry and why given that when he went to the Dursley Harry read his mind, also living him on Azkaban so that he couldn't have a say in how Harry was raised.

"I can't believe Dumbledore would do those things, he was supposed to be the Leader of The Light the most powerful of all of us."

"First of all, Dumb-as-a-Door is no Leader of The Light, that's a fucking made up title He made, second of all he is nowhere near as powerful he wants you to believe it's all because the British community of wizards and witches is so fucking closed off they don't know shit of what's going on the real world. There's hundred of people out there that could give him a run for his money. More will be coming in the future.

"His super city destroying duel against Grindelwald was all a fucking lie, he stunned from the back while Grindelwald was tired from making love with him, yeah both are homosexual. He didn't killed him as he made everyone believed, he imprisoned Geller on Nurmengard who is still alive to this day."

So he started telling him the story of Albus and Geller from teens where they made the "For the Greater Good" (German: "Für das Größere Wohl") to control the wizarding world and where they killed Albus sister on a 3 way duel with Albus brother who wanted to kicked Geller from the house, which Albus wanted to use cunning and Geller force, and all that shit.

How Albus created Tom Riddle or Lord Voldemort as he liked to be called but he got more powerful that he wanted and that then the prophecy came where either Neville Longbottom or Harry would be the one to end him, so he went out of his way to control one of the kids to mold his weapon.

"HAHAHAHAHA oh how I imagine the revenge you are going to give to that fucking muggle lover, right kid? And from those hundred more powerful than him I imagine you are one of those at the top, no?"
