Harry knows
Harry was so tired, tired of hiding who he is, who he loves, he is also physically tired. Harry lays motionless on his bed next to his packed trunk staring up at the ceiling thinking, just thinking. He knows everything about everyone which was extremely helpful but also extremely overwhelming. Regulus had outed himself as in fact not dead, Harry knows this was on purpose, Regulus was more then capable of not getting caught in public. Harry knows that Regulus is the new Defense Against the Dark Arts professor even though technically Regulus is not supposed to have told any of the students.
Regulus is collecting Harry from the Dursleys today, in fact Regulus should be here any minute now. Harry trusted that Reg would be on time and Harry has already told the Dursleys his magical guardian would be coming to collect him today, Harry was dressed and ready with his trunk packed now he has nothing to do until Regulus arrives. The Dursleys were more then apprehensive to let a wizard into their home but Harry had assured them that they had no choice.
Harry heard a faint CRACK* so he grabbed his trunk and walked downstairs. Regulus was standing in the doorway while all three Dursleys looked at him as if he was especially disgusting which was not true, Regulus looked his usual clean and perfect self. "Hi Prongsie are you ready to go?" Regulus asked. "yes father" Harry replied. At the title father both of the Dursley parents eyes widened comically, that had been Harry's intention as even though he did see both Regulus and Sirius as father figures he normally called them both by their names. Regulus extended his arm and Harry took it and they apparated out.
They appeared outside of grimmuald places 11 and 13 Regulus slit his wrist, watched blood pour out onto the ground and suddenly a new place was appearing number 12. Harry walked in with Regulus at his side, they entered the sitting room and Sirius was sitting next to the fireplace. "Sirius!" "Harry!" Harry practically threw himself at Sirius. "How kind" Regulus says sacrastically. "Sorry Reg" says harry and then he bear hugged Regulus.
-------------------
Harry walked along to the train with Regulus, Regulus would be taking the train as was protocol when a professor was dealing with magical exhaustion and could not apparate. Regulus's specific case came from a horcrux mission, harry knows. He had overheard Remus and Regulus discussing the issue as Regulus does not want to discuss these things behind Harry's back but will with Remus because he already knew.
In fact harry knows more than any 15 year old ever should. He knows Voldemort was back, He knows about Voldemorts 8 horcruxes including himself, he knows weasley and granger are fake friends using him for his fame, he knows why blood purists think the way they do, he knows dumbledore is a manipulator, and he also knows that Voldemort and his death eaters are residing in Malfoy Manor.
But these were things Harry wont get another chance to think about for a few hours as he and Regulus are now boarding the Hogwarts Express and Harry would have to deal with the dynamic duo. Regulus knows that Harry doesent like them and so he might help Harry make up excuses but it was still a sad thought to have to sit with them for 9 hours.
"Are you okay? you look like your disassosiating." Regulus said
Harry snapped back into reality "Sorry, Reg."
They are in a train compartment apparently harry had already taken a book out, he looked down at it 'Avanine peverall's journal' he had pulled out a peverall journal. he quickly put it back and pulled out a book on spell creation instead, that would raise less suspision.
The door opened. Harry jumped back. it was not Ron or Hermione, it was.. Draco!
"I can't stick around but i thought i'd see my uncle and boyfriend before i joined my friends in the slytherin compartment." Draco said
Draco wrapped Harry up in a big hug before rushing out after a very irritated Pansy Parkinson.
The next guest is less welcome, one Hermione Granger flashing her prefects badge. "Hi Harry! how have you been!" she said completely ignoring Regulus and sitting down next to Harry, this would make for a very long train ride indeed.
The next guest is even more unwelcome then the last, one Ronald Weasley who was also flashing his prefects badge, this time welcoming himself without asking as harry had thought he would. The tension in the air was so thick you could cut it with a knife as Hermione and Ron tried to figure out why Harry was sitting with Regulus, whom they thought was just dead Sirius's brother and not Harry's favourite father figure as he actually is. They would also be wrong in the assumption that Sirius was dead, but in all fairness Sirius did fake his death last year.
--------------------
Harry and his actual best friend, Neville walked to griffyndor table as Harry waves Regulus off towards the staff table. They were muttering to each other in rapid fire french about what Harry should do about Voldemort. Neville had already known french due to his pureblood upbringing and Harry had learned when he originally started spending time with Regulus. It didn't matter that some other people also spoke french because all the griffyndors refused to speak anything other than english and the other houses were to far away to properly hear them.
"What are you even supposed to do? He's residing in your little boyfriend's manor and attacking Voldemort would mean attacking him." Neville said
"I honestly don't know, Draco sent me the list of wards so i can figure out how to get past them but i'm unsure of that's the right move." Harry replied
"What do you mean 'unsure if that's the right move?! this is Voldemort we are talking about." Neville said
"I know but i need to be more deceptive if i'm going to stage a break in, and anyway he still has his horcruxes." Harry replied, starting to get frustrated.
"Yes i suppose you should wait until there are none left. Didn't Regulus task you with finding one of them?" Neville asked
"Yes. The lost diadem of ravenclaw, He says he thinks it's in the room of requirment but he's not sure." Harry answered
They both sat down and Hermione sat down with them, much to Harry's hidden displeasure. The sorting went by rather quickly as Harry and Neville spent the time playing a game of exploding snap. Then dumbledore sigaled everyone to go quiet, he was about to give his annual beginning of year speech. "Welcome or welcome back, i have a few annoucments before we all become to befuddled with our excellent feast. Firstly i wil announce the staff changes, This years Defense Against The Dark Arts professor is professor Black, good luck professor. Secondly we recently found out there was a curse on that particular teaching post, it has been removed. Lastly as Sirius Black died we no longer need the dementors at the exits and they have all returned to there post's at Azkaban fortress. Now then let's eat." Dumbledore finished talking and food appeared on all of the tables.
Harry immediatly began pilling food onto his plate, nothing would ever be better than Hogwarts food. Still, the castles walls tried to remind him of being a first year oblivously happy and far too trusting, but Harry did not want to remember, it was too painful hating slytherin, trusting his trauma bonded so called 'friends' and trusting Dumbledore blindly. Of course Harry also had good memories here he let the castle remind him of that instead. Meeting up with Draco in secret to play a plethera of games, Him and Neville in corridors trying to recreate some of the marurders pranks, not to many of those memories though, he tried not to give Minerva a heart attack.
Harry was pulled out of his thoughts once the feast ended. He and Neville walked towards griffyndor tower together, once they arrived Harry immediatly headed up towards the dorms to put his dark arts books away before someone saw them in his satchel and decided to ask questions.
After puting the books through extremely HEAVY wards Harry was tired and decided to go to bed early, not before reading a rather intresting chapter on parselmagics though.
