Harry stared at Lily who was looking at Baby Harry who was playing on the younger Sirius.

"So your only purpose to come here is to save your mother and myself but at the same time make it easier to kill You-Know-Who in your time?" James asked.

Harry smiled, "Yes."

"How are you going to do that?" James asked, looking at Harry.

Harry sighed and looked at the older Lupin who was playing with Harry's wand, "Can I tell them?"

Lupin nodded and he looked at the older Sirius, "Do you think it will be okay?"

Sirius smiled, "Sure sure."

Harry took a deep breath and saw all eyes on him, "Okay well Voldemort has these things called Horcruxes that keeps him alive in my time and I know that he already made them. I want to destroy some so I won't have to worry about them when I get back."

"How do you know that he already made them though?" James asked.

"Dumbledore," Harry said looking around at everyone.

James sat up straight, "Okay."

"What are they? I've never heard or read about them," The younger Lupin said.

Harry sighed, "You wouldn't have been able read them at Hogwarts because Dumbledore took all the books out. Horcruxes can be anything, you chose what they are, but you need a lot of Dark Magic to make one. There's a spell that you can do that tears your soul apart. Horcruxes are the things you use to hold the pieces of your soul, to protect it."

"And how do you know what they are?" James asked.

"Again Dumbledore," Harry smiled. "He gave me everything that I'll need to hunt them down and destroy them."

"How do you destroy one?" Lily asked.

Harry stood up and took out a truck and waved his hand at it and it enlarge to a normal sized one. He opened it and everyone gasped when they saw the sword of Gryffindor. "With this. We destroy it with this."

"Where did you get that?" James asked dumbfounded. "Do you know what that is?"

Harry chuckled, "This, James, is Godric Gryffindor's Sword and Sirius and I stole it."

"You what?" Lily almost yelled.

"Long story," Harry rubbed the back of his neck. "But anyways, all we have to do is stab it and then it's done."

"Just like that?" James asked.

"Well, yeah," The older Sirius said smiling. "Just like if we were to stab you. You'd die pretty quick."

James cocked a smile, "Thanks Sirius. I appreciate it."

"Not that I want you dying," Sirius replied.

"How many are there?" James asked Harry.

Harry placed the sword in his truck, shrunk it and placed it in his pocket, "Well, there was seven."

"Was? Did you already destroy some?" James asked wide eyed.

"I destroyed one when I was a baby, which I haven't done yet seeing that you're alive. Uh, but I destroyed one in second year, then Dumbledore destroyed some in my sixth year and yeah. So in my time there are only five more but here we have less."

"Why less here?" The younger Sirius said getting serious.

"I have to watch what I destroy because I only learned about them because Dumbledore found one, the ring. I can't destroy the ring, diary or his snake. Which leaves us with a locket, a cup and then something of Gryffindor's or Ravenclaw's."

"Well, first thing first then. The locket. How do we find and get that?" The younger Lupin asked.

"Padfoot, is your brother still alive?" Harry asked.

"No." Both Sirius' replied.

Harry turned to the older one, "I know he's not, Padfoot. I was asking the not old one."

"Oh my bad. Sorry," Sirius smiled. "It's hard when we have the same name."

"No, my brother died," The younger Sirius repeated.

"Did your mum die yet?" Harry asked.

The younger Sirius looked at him, "Why do I have feeling that we are going to need to break into my mother's house to get this locket."

"I take that as a 'no'," Harry sighed. "And yes. I think that we will have to break in your house unless I can think of another way."

"Listen we will do one at a time," The older Sirius said. "I say we do the locket last. We should try and get the harder ones first."

"The cup and either something of Ravenclaw's or Gryffindor's," Harry said. "I'm guessing that the thing that belongs to either Ravenclaw or Gryffindor is at Hogwarts and the cup might just so happen be in Bellatrix's vault at Gringotts."

James mouth dropped open, "So you're saying that we have to break into not only Hogwarts and Grimmauld Place but Gringotts, as well?"

"Look, I haven't figured everything out yet. Give me tonight to think it through, okay," Harry yawned.

"You can sleep here. We have enough room," Lily smiled taking the already sleeping baby from the younger Sirius.

"Thanks," Harry smiled back. "But I don't need a separate room, I can just crash with Sirius."

"Whatever you want, dear," Lily replied.

Later that night with the older Sirius and Lupin and Harry……

Harry cased a muffliato on the door and then turned to Sirius and Lupin, "Lupin, listen tomorrow Sirius and I are going to break into Gringotts and get the cup but you can't tell anyone. I need you here as a distraction."

"Wait! What are you talking about?" Sirius asked. "I was not informed about this."

"You weren't informed because I just thought about it," Harry pointed out. "And it's Gringotts not the Ministry."

"Yes because the Ministry would be so much better," Sirius said sarcasm lacing almost everything. "I mean really. Getting into Gringotts should be easy and then getting down to Bellatrix's fault and to top it off we get to break in to it and steal a cup! Man, I'm excited. Let's hope we don't get caught and end up dying."

Harry stared at him, "You make it sound so easy."

"How are you going to do it?" Lupin asked.

Harry smiled, "You don't need to know. All you need to do is occupy James and Lily and everyone else."
