Family talk.

"I want to talk with you both about something." Calling his parents to pass them a very important information.

"What happened?"

"I plan to take name of Prince family. This community is outdated and really exclusive… I have potential to change things…however, I require time. To grow. To learn. To become great. There are things accessible only for people with heritage. I am sorry… I understand that they hurt you both in many ways…" It was primarily her heritage, and he could clearly approach things in more magical way. Excluding his biological parents from his life to make things easier wasn't pleasant thing.

"You don't want to be associated with my name anymore…It's…" Tobias believed its his fault as basically entering self-blame mode again. Severus intervened in a middle of the sentence.

"Stop blaming yourself for their deeds. I need this name to open some paths… I won't remove your name. I plan will be proud member of Snape family…also member of Prince family. It's only name… Nothing changes."

"Don't worry son. I understand… It's little painful but... I understand that they are all dead… You are not them… I will support your decision." Eileen had too many terrible memories related to their family, however she understood wizarding society. Pure bloods detested muggleborns and his lack of heritage would close many doors before even trying to speak.

"We need to visit Gringotts… I want information about procedures and ther fate." As underage wizard he couldn't make deals without official guardian.

"When do you want to go there?" Recognizing her slight unstable emotions, he decided to give her few days to process this situation.

"There is no hurry… We can go next week." His product wasn't ready for public yet, and he could some time to ensure she is comfortable.

"Okay. Next week then…" After few more minutes of chit chat, they went to their own tasks.

His goal was to protect insides of his inventions, ensuring mystery around the blueprint.

'I should think about existence of x-ray objects too. Moody had an eye with such power…' It couldn't be just protection from reaching insides, and it needed to secure from using such methods.

'Those two need to separate… One with blocking the view and second with reaction on intentional dismantling or breaking.' It needed to be protected from attempts to charm by others too.

'I should think about overall IP protection spell.'

Knock. Knock. His father came to talk, he genuinely appreciated the fact of knocking. John's parents didn't care much about his privacy, entering his room all the time like doors didn't exist.

'It's no like… I was doing things…I didn't want to be seen… Especially in my teenage years.' It prompted him about possibility of enchanting object to hide from underage children.

'Barty was actually talented guy. I think wizarding parents should receive the compulsory tutorial on raising children. It would prevent much shit from happening in this place. Wait… It's practically the same in a normal world. At least those children don't grow up into spitting flames snake face.'

"Come in." Almost forgetting about his father waiting for his reaction.

His eyes revealed some inner conflict happening inside of him, not knowing what to say.

"Eh. I don't… I came to talk about… I don't know. Fuck. I am sorry. I have had no father in my life. I almost ended doing the same to you. I don't know if you accept me as your father. I know you suffered and will suffer because of me. I am ordinary person without…" Severus felt like his words were going too far, stopping him with some simple words.

"Stop. You are my father. I will never blame you for those things… Your lack of magic doesn't bother me. I don't want you to blame yourself. It's meaningless…and utterly stupid. I took away your possible rehabilitation… I am not child anymore… You need to understand that those feelings won't change things… you have no control of… It's little problematic… because it's the moment, you come to me and give me bear hug…and I uncomfortably accept it…." Hearing those words, he hugged tried to hug him with all strength in his body. Severus didn't even budge as he took many more potions than him.

"I am sorry… If you ever need anything from me… Just ask! I will do everything I can to help you!" Tobias felt relieved by his son words, losing part of his emotional burden.

"Father. Focus on mother… She needs you! I hope you can be your best for her."

"You don't need reminding me. I would rip my heart for her if she asked me." His only thoughts fell if they would eventually get to the point of having another child.

'It would be great for them. I won't have mind or time to be the child they wanted.'

After his father left, he came back to working on new spell.

'It was age line… If I modify its intent to not pass anything instead of underage people.' Remembering the original chant, he used it on his own door for a test.

"Fili Prohibire!" His doors were shrouded in the magical barrier, and he tried to pass through and got repulsed.

Experimenting with different words to change incantation into protection against unauthorized, days passed without any progress. Creating new spells wasn't easy process, he needed to be patient and ready for unexpected effects. It didn't only require great knowledge and creator of new spells should possess open mind for long fruitless experiments.

'Other spells weren't created in days either…' Each of Severus personal spells took him long time to develop with many accidents on the way.

'Bellatrix will be married in few months…' She had finished Hogwarts before Petunia started her year.

'Barging into Black's property is death wish… I need to talk with her away from her parents.' His only way was to wait in vicinity of their manor.

His decision was right, Bellatrix left her house and walked without care.

Using opportunity created by their leave of the mansion, he followed her from far. Her goal was simple shopping in Diagon Alley.

'Their awareness is trash… Anyone could ambush her without bigger problem.' Using opportunity to understand situation, he entered her mind, and what he found was really horrible.

'Her own father…' Bellatrix wasn't crazy from the beginning, and her later unstable state was result of multiple careless mind invasions. Cygnus Black punished her with such attacks after her every disobedience. Every modification created small crack on person mind and personality. On small scale those cracks would mend after time without permanent damage, Cygnus didn't care much about consequences of his actions. Putting his pride over his daughter mental health was really too much.

'Am I right person to judge others? I almost killed an innocent…' His thoughts fell on next action, and her mind was like house of cards. Anyone could blow at her with right spell and break her existence.

'Mind healing? Snape invented some soul healing… It's different concept.' Her soul was fine for time being, obviously her obsession with dark arts might change this fact.

'Everything is logical now. Her mind is programmable… At their first meeting, Tom rebuilt her into the perfect subordinate. Some parts managed to stay…like ability to recognize Draco as family.' Leaving her like this would seal her fate, only chance would be programming her by himself.

'I will heal her mind in future… Right now… I can only save her by doing the worst.' Letting her be wasted as snake follower would make him equally evil. There was some feeling of attraction to her charming appearance as well, he decided to go ahead of Dark lord and program her into his subordinate.

Putting small note into her pocket with some magic, she read its content and separated from her sisters.

'If you want to know why Death curse...' Luring her with usage of her failure in grasping spell, promising her solution.

"Who are you?! How do you know I cannot succeed with Death Curse?" Pointing her wand at him without any thoughts, thinking about his as stalker.

Using few simple spells, he knocked her out and started modifying her memories. It was cruel as her mind almost collapsed, he did only couple alterations to appear in her life.

"John? Why are you here? If my father discovered us together… He will kill you!" Her voice was shaking from fear, and her father was muggle hater and image in her mind was muggleborn wizard.

"Don't worry, Bella. None can hurt me. We need to escape from him. I cannot let him destroy your personality by constant mind raping… Come with me. In few years, I will change this world. Do you believe me?" Using his ideals to create a perfect world without blood supremacist and families built on love.

"I do… I am part of House of Black. I cannot just leave. They will disown me!"

"Your sisters will understand. Rest isn't important. Your parents don't genuinely cherish you. They merely want use you as pure blood incubator. Bella… I might be not rich. Give me time, and I will be wealthiest man alive. Please… If you stay with them. You will be forced to become an evil witch…" His persuasion started showing effects, she was aware of her real value to family. They didn't care about her feeling or ambitions, her only life was marrying pure blood and having pure children.

"I will come with you… I will send owl to my sisters and take my things from house." Both of her sisters were currently in school. They would return for holidays, she wouldn't be there by then.

Being in vicinity to intervene in any case, it seems both of her parents weren't home.

"We will temporarily live in hotel. I recently invested most of money in project." Bellatrix didn't take money from her house, and she didn't want to owe anything to her family.

"It doesn't matter…" Altering her mind created new path for Bella, however this made her state even more vulnerable.

'It's odd… They didn't teach her Occlumency…' Remembering her teaching Occlumency to Draco, things pointed at Voldemort using this technique to ensure none would fix his modifications in her mind.

"Bella. You need to learn Occlumency." His alterations didn't twist her into the fanatic lover, and he just created image of him being her close friend. This way of conquering woman would feel fake, she wouldn't be any different from sex doll in her current state of mind.

'I want to conquer her… but not now. Not when she is fragile and vulnerable. I will think about it after restoring her mind… This isn't true her. She is broken by the world…On outside very sexy and beautiful woman. Her mind is in chaos… It would be like sex with a drunk woman.'

"Okay. Father forbid us from learning…" It wasn't easy to attack mind of Occlumens, and he couldn't allow them to get out of his control.

Severus could nothing but sell all his remaining potions to purchase house for Bellatrix to live, and his current house was already too stuffed in this moment. Adding her to equation would create a really uncomfortable environment for everyone.
