Sort of got bored of 1969 at this point so it's a little fast. Hopefully still enjoyable though.
Harry couldn't wipe the smile off his face the next morning and nothing seemed to take it away. Harry had hoped that when he and Ginny returned the group well after mid-night that the others wouldn't think much of it. However Ron's "older brother" look, Hermione's "I hope you didn't do anything stupid" look, and George's "I really want to make a joke but I know I shouldn't" look told Harry that they all did indeed suspect something. This was confirmed after breakfast when Ron asked Harry to have a private conversation.
The two walked just outside hearing range of Ginny, George, and Hermione who all remained in the tent. "Harry I don't know what you and Ginny did or didn't do last night and I really don't want to know. I know you care about her but I need you to hear me out as Ginny's brother for a moment. The last thing I want is to see her hurt or in a bad situation" Harry went to interrupt him, "I know you wouldn't do anything on purpose Harry but things happen. Just don't put you and Ginny at risk for heartbreak or whatever" Ron finished and he and Harry stood there in an awkward silence. "I promise that no matter what happens I won't hurt her" Harry finally replied to Ron's speech and that was the end of the conversation and they headed back into the tent.
Three hours later Harry found himself on a Gringotts boat under the invisibility cloak heading to the vault he hope held the cup. Harry had timed everything perfectly the door opening just long enough for him to sneak in, getting on a boat heading in the direct of the vault etc. Of course he had no idea how he was going to get into the vault when he got there but he was hoping that he lucky streak wouldn't run out for a little bit longer. Harry spotted the vault and jumped off making sure to make no sound and not to come out for under the invisibility cloak. Harry luck wasn't out yet, he used his wand to unlock the vault and the door open easy. Maybe Gringotts security wasn't quite set up fully yet?
Snuck in the vault grabbed the cup and back up locking the vault all before the same boat returned. Harry snuck onto it once again and waited out the ride back to the main area. Once the boat arrived he slipped off and back through. Just as Harry was preparing himself to go through the door Gringotts alarm went off. Harry in a panic jumped up and opened the door himself. Off course the nearest Goblin notice the door had been open and now Harry was running down the street of Diagon Alley with several Goblins and other "security" people chasing after him. The invisibility cloak was slipping off and rather than risking losing it Harry ended up revealing himself.
Thankful no witches or wizards know what was going on before he past them. It was also a good thing Harry was good with his wand and was able to block any stunning spells anyone did returned to "The Leaky Cauldron" where the others waited (with fake identities and slight disguises just in case). "Run!" Harry shouted. It did not take long for that order to be followed. Ginny, Ron, George and Hermione were up and moving before the "security" was able to get anywhere near. It took another four bocks before the group was able to lose the "security" who decided it was now helpless to catch them as they couldn't cast spells in the muggle world without causing a huge scene returned back.
"You okay?" Hermione asked him once the group was sure they were safe. "Yeah", Harry replied holding up the cup, "Still a lot easier than last time." After returning to "base" as the group now called it. They immediately started figuring out how to (A) get the diadem, which led to (B) how to get into Hogwarts and of course (C) how destroy the Horcurxes. This had to be done rather quickly as once people realized the Gringotts had been broken into people who want to make sure everything in their vaults were accounted for and this would most likely led to a discovery they didn't want Voldemort to discover
The use of polyjuice potion was out this time as it took quite some time to brew and although Hermione had packed all the ingredients no one had thought to make it ahead of time. The decision was made to go to the Shrieking Shack and hope that the secret passages were already open. It was and now Harry had dropped Ginny and George in the room of requirements to retrieve to diadem and was returning to get Ron and Hermione to go with him down into the chamber of secrets.
The plan was to kill the basilisk and use his fangs to destroy the horcurxes. They of course again had no idea how to accomplish this but hoped that the sword of Gryffindor would offer some assistance. They were now in the chamber (under the cloak hoping to surprise the basilisk). Turns out there was no need the Basilisk was asleep. This was turning out to be "too good to be true" but Harry pushed it to the side, maybe fate was simply on their side this time. The sword did appear rather quickly as well.
Harry held his breath as he inched toward the Basilisk afraid to make any noise to wake it. In one quick motion Harry sliced its head off. They took as many fangs as they could and the sword as well. The group was now back in the tent. "I wasn't even aware snake's slept", George stated after group had finished exchange stories (not that there was much to tell on either end). "It's more of a sleep like state, we just got really lucky" replied Hermione.
"We've been really lucky", replied Harry. On that note they began to prepare for the reason they had come here before that luck ran out. They decided to waste no time, they gather the horcurxes, the fangs, their wands, and the sword and headed out to where Hermione and Ron had previously seen Voldemort. This was it. Whether or not fate was truly on their side they were about to find out.
