In the morning Harry left with two way mirror and a promise to contact Tom every night. The train ride and welcome feast went as usual and he found out that Snape would be their new defance professor and Slughorn will take potions and have invited him to join the class, there he find an old potions book which belongs to a half blood Prince which helped him alot and he was going to take special lessons from Dumbledore which he was not looking forward to.
Week in session, Dumbledore asked him to come to his office for lessons, he had went not knowing what to expect only to be shown a memory of Tom's family and how his crazy uncle and grandfather treated his mother, he was feeling very offended that Dumbledore had invaded somebody else's memory to his own benifit and then he was told it is so he can understand Tom better. Harry left the office with one thought in mind to tell Tom what had happened and to find real purpose behind the lessons.
After everyone fall asleep Harry went to the ROR (room of requirements) and asked for a place where he can apparate and went to Tom's room, there he found him searching for something in the shelves and hugged him from behind "Harry, what are you doing here" Tom said in surprise "I missed you and wanted to tell you something" Harry said "and you couldn't say it on the two way mirror" Tom asked raising his eyebrows "no, I wanted to know what to do as well so..." Harry trailed off looking away "ok, sit down first, have you eaten" Tom asked leading him to the bed "yes " Harry said sitting down still not meeting Tom's eyes "ok tell me what is it" Tom said "Tom I promise I did not know he was going to do this I mean I know that I have no right to find things like that if you don't want to tell me and I really wanted to wait till you are more comfortable to tell me about it" Harry rumbled on but Tom inturepted him "Harry get to the point what did you find out" Harry sighs in defeat "when the session started Dumbledore wanted to give me lessons to 'defeat you', I thought it was some advanced training or something but turns out he was telling me about your past, today he told me about your grandfather and your uncle and how they treated your mother" the paused to finaly look at his eyes only to see worry instead of anger "I didn't wanted to see really, I know how living in a abusive family feel and for people to find out about that without you wanting is the worst".
Suddenly Tom hugged him tightly "you really are something else, people would be disgusted to find the kind of family I came from but you feel sad on my behalf" Tom said his face still buried in Harry's hair "well like I said I know what it is like" Harry said tightening his hold on Tom "I was actually raised in an orphanage, my mother died giving birth to me and my father refuse to acknowledge my existence" Tom said after some time holding Harry close "thank you for telling me this it must have been hard telling me this" Harry said giving him a small kiss.
"I have something to tell you, something very bad" Tom started sitting up detangling himself wanting to put some distance between them because he knew Harry would feel very disgusted with him after finding out what he did"I know why Dumbledore wanted Slughorn to come to school and why is he showing you these memories" Tom said "what is it" Harry asked concerned " I um Harry I" he started "Tom, I know what you have done in the past but I am still here aren't I just tell me" Harry said "not this you won't stay after finding out what I have done" Tom said "Tom just tell me" Harry said.
"Do you know what a horcrux is Harry" Tom asked, Harry shake his head "it is where you put a part of your soul in something so if you ever loose your body you can still come back" Tom said "so you make a horcrux" Harry asked as if it was not a big deal "I made six actually I wanted to made seven but the night I was going to make the last one you defeated me" Tom said with a small smile "I did not defeated you your spell just back fired and so what if you make six or seven horcrux" Harry said "you don't understand Harry, in order to make an horcrux you have to kill someone" Tom said "I know you have killed people Tom and you told me why so why does it matter, just tell me Tom you are starting to freak me out" Harry said "I was well when I made my first horcrux, I was sixteen at that time and I killed a girl in the girls bathroom on the third floor in Hogwarts, the dairy you destroyed in your second year was my first horcrux" Tom said "but myrtle was killed by the basilisk" Harry said with a frown "and I send the snake her way and that's not it, in order to put a part of my soul in something else I had to rip it off and broke myself in six pieces" Tom said looking ashamed, he was not ashamed that he made his horcrux's but that Harry have to live with a person with broken soul, he told Harry the process to make a horcrux and what they were.
"I am sorry, it must have hurted so much doing something like that" Harry said coming to sit on his lap and hugging him close, Tom was shocked to hear him say those words he had expected anger and disgust not care and concerned "you are not worried about being with a broken person" Tom asked "I am just as broken as you are and I don't care either ways I want to be with you and nothing you do or say can change that" Harry said with a grin "you really are something else aren't you" Tom said shaking his head with a small smile and kissed him.
"I don't want to go back, those lessons feels like intrusion of your privacy" Harry said after some time "but you have to, if Dumbledore knows what my horcrux are and are trying to find them I have to know and you are the only one except my inner most circle who knows about them" Tom said with a sigh he really didn't wanted to send harry back but he know he had to "ok, I will tell you if he finds any of them" Harry said getting up and with a parting kiss he apparated away.
