Responses for reviews:

Mrs. Sniffy: Hey guys. I'm going to study to my English and History exams so I left these two to response your reviews. They know 'almost' everything.

Harry: Hello. I'm Harry. Someone saw Regulus?

Regulus: Here you are Harry. You know what's going on?

Harry: Yep. Mrs. Sniffy left us here to response her reviewers.

Regulus: For what we are waiting?

Harry: Okay. First Silver-Entrantress-Elf

Regulus: She is happy that you like Mr. Tibbles. Pity that I don't. But I'm on JKR, Mrs. Sniffy and Harry's mercy if it come to name me.

Harry: Sexy Black now.

Regulus: Did she told you that you have funny name. And I said this before but I'm going to reenact. She like this but I'm not. Thanks I explain to him :::pointing at Harry::: why I end as cat. And why Mrs. Figg had so many cats?

Harry: That's a good question :::staring at Regulus:::

Regulus: Go and wash your mind Harry. This story has PG rating. I don't know why she had so many cats. But I'm sure one – this is not my fault. Maybe she is Mrs. Sniffy in wizarding world because they are both crazy about cats?

Mrs. Sniffy: :::Putting her head out of History book::: Said this once again Regulus and you are going to change your last name from Black to Pink. Clear?

Regulus: Crystal clear. Krylancelo now.

Harry: Well, he is not her cat anymore. Mrs. Sniffy said that she likes these too but this where Pussy is a good guy or at least where he is becoming to. And she mumbling now that she left challenge on her bio but no one responded so she start this herself.

Mrs. Sniffy: :::once again from her History book:::

Regulus: I didn't anything wrong.

Mrs. Sniffy: Oh shut up Kitty. It's not about you. I want to thank Jemma Blackwell for wonderful beta job in this chapter and for fact that she had enough patience to bear with my grammar. :::going back to her history book:::

Harry and Regulus unison: Thank you too Jemma Blackwell.

Harry: Well who is next Kitty?

Regulus: siriusblack. Harry get down from me it's not him. :::wiping dust from himself::: Well thanks. It's good to know that someone likes you. Mrs. Sniffy says thank you too. And she says also that reviews make her day.

Harry: jo0609 next.

Regulus: :::trying to peek in Mrs. Sniffy secret notebook::: :::coming back massaging his hands::: She refused to tell what's going with Sirius. She said that my business is watching Harry now. What's going to happen in next chapter is hers job and she tell you next time. And yes I'm cat.

Harry: And no one is going to take Sirius place no matter what you all think about this.

Regulus: In some ways I'm going to, yes. But not completely.

Harry and Regulus in unison: Read and review. She likes this.

Brother, brother, brother

No matter who's right or who is wrong

I just want you to know my love's still strong

I wrote you a prayer with your song

Chapter Six: Harry's New Pet

Regulus nodded and answered, "In his own fur", then changed into a big, black shabby cat with gray eyes.

Harry's jaw dropped and he bent down to scratch the cat's ears. Regulus purred loudly, then jumped onto the desk and changed back. Regulus crossed his legs and smiled nonchalantly.

"What can I say Harry? I always had a cat-like nature, the opposite of Sirius and Mirzam. They were dogs - both faithful and devoted to their friends. Always in action. Typical dogs. And I... I was always idler, proud, independent, reserved in making friends – practically I never had them – I always had to have order around me, I love tidiness and I had to shave at least once in a week. Typical cat", answered Regulus.

"It's hard to shave when you are a cat in an old woman's house", teased Harry.

"Oh, you don't know how hard. I used to shave when she was out, and I rarely changed into my human form", answered Regulus, starting his stretching again.

"Did you do your tidying by yourself?" asked Harry.

"Of course, I had to be extremely careful not to leave any sign that I was still alive. If I wouldn't have cleaned up around myself before I arrived to Mrs. Figg's house. And don't look at me like that Harry, I didn't kill anyone, unless you count Stubby. But he was dead long before he asked me for 'help'. I realized that I couldn't help him, he was suicidal. And even if I had refused to help him, he would've killed himself anyway." Regulus subsided. "I still feel guilty about his death. I checked later in the Aurors' records to see how he was killed. He didn't suffer. It was just Avada Kedavra", sighed Regulus.

"But you didn't point your wand at him!" exclaimed Harry.

"I didn't. Nor did you. But you still blame yourself about Sirius", said Regulus.

"How do you know that?" Harry paled.

"I heard you last night, you whispered 'I killed him'. I have a good sense of hearing", answered Regulus.

"Did you blame me for his death?" asked Harry, trying to not look at Regulus.

Regulus saw this in a glance, then jumped off the desk. He stood in front of Harry and put his hand on Harry's shoulder and said, "No, Harry. I don't blame you. Better wizards than you were fooled by Voldemort and you have to accept this." Regulus squeezed Harry's shoulder. "And Sirius knew the risk, he knew about this when he joined the Aurors and later when he joined The Order of the Phoenix. They all knew the risk, Harry. But they were willing to die for the idea."

"Which idea caused people's death?" exclaimed Harry, terrified.

"That there are things in this world worth dying for", answered Regulus, looking straight into Harry's eyes.

Harry recalled that Sirius said these same words a few months ago. Then Harry looked back into Regulus' eyes, he saw no fear in them, no blame, only... love?

"You are the same as Sirius", Harry whispered, lowering his gaze.

"I'm his brother Harry, I should be", Regulus squeezed Harry's shoulder again.

"I know that you are his brother, he told me", Harry said "Do you mind if I ask about something?"

"Shoot."

"Sirius told me that you believed in what your parents told you about..." Harry started but Regulus interrupted him.

"That being a Black is something royal and all this pure-blood nonsense?"

"He told me that you were soft enough to believe them. Oh, sorry Regulus."

"No reason to apologize Harry. There was a time when I believed in that. All three of us were raised in that manner - You are a Black, you are a Black's ward so act like one of them. Hate mudbloods, hate half-breeds, act like you are the ruler of the wizarding world - I think that both Sirius and I will do penance for the rest of our lives for thinking that way", answered Regulus.

"Why did you change your mind, about muggleborns and the rest?" asked Harry. He raised one eyebrow because Regulus blushed.

"My seventh year. I had a crush on a muggleborn Gryffindor from my year. Imagine what could have happened if my parents found out about this... The last son of the Blacks – because they banned Sirius after he ran away – a Slytherin in love with a Gryffindor was enough to made them mad and a muggleborn... I was lucky that they didn't find out about that. We had a few secret dates, more we were secretly engaged." Regulus stilled.

"And what happened later, with her, with you?" asked Harry.

"I... I... I broke the engagement. I ran away. I was scared for her, Harry. I knew my parents and the rest of my family and I knew what could have happened if I announced our engagement to them. They would not have pardoned me and not in such a short time – barely three years after Sirius had run away. Imagine the scandal: Second son leaves Blacks' house because he wanted to marry a muggleborn Gryffindor", Regulus said. "I've always had second thoughts, maybe if I didn't back away our lives could've been different. Maybe if I had married a muggleborn Gryffindor, I could have had better relations with Sirius. Maybe I wouldn't have taken the Dark Mark. Maybe I could've had kids and they could've come to Hogwarts and been friends with Sirius' kids. I don't know Harry. Now I know I should have stayed. But at that time I still respected my parents will, and I decided to end this. Back away and never get married. I felt so miserable after that, and I realized that the world isn't divided into purebloods and mudbloods, but into good and bad people. But when it came to me it was too late. I was ready to come back to her and beg her for forgiveness but it was too late. Four Death Eaters killed her shortly after the holidays ended. I was in shock. I moved from my parents' house after graduation but then I hid myself in London for a few weeks. I knew that Bellatrix became a Death Eater and when I was at the dinners in my parents' house, she often offered me the chance to become one of them too. But I didn't want to, I didn't want to become one of the people who killed my fiancé. And I couldn't tell them why I didn't want this." Regulus' voice sounded angry, and his right hand traveled to his left forearm, clutching it slightly.

Harry smiled sadly and squeezed Regulus' shoulder and dragged him onto his bed where they both sat down. After a few seconds both leaned against the wall. They sit in silence. Regulus had a spiteful look on his face, which softened after a few minutes. Then he turned to Harry and smiled.

"Want to know what it means being a Black?" asked Regulus.

Harry nodded.

"We always got what we wanted when we were kids and I think it wasn't good. Our first years in Hogwarts we acted like 'We are Blacks, we are not subordinate to normal rules' but we learnt that Black or not we must follow certain rules like the others, if we didn't want to have a detention or two. I was a good student, and when I found out that I should shut my mouth sometimes and act like the rest of the students, I did it", said Regulus.

"What about Sirius?" Harry interrupted.

Regulus smiled widely.

"Sirius was Sirius and another story. He was a rebel. So was Mirzam but she couldn't be any other way. I remember that when they came back for Christmas in their first year, Sirius told me that he made a bet with James Potter about which one of them would have the most detentions by the end of their seventh year. The prize was that the loser buy the winner a motorcycle", said Regulus, still smiling.

"I think I know who won this bet", said Harry.

"Sirius, yes, he won. I must admit that your father was quite good at this, but somewhere in his seventh year James acquired a moderator."

"In?"

"Your mother. I think that pulling pranks and getting detentions was hard when you had a girl who was against that. So Sirius won. 1417 detentions for seven years to James' 1349. He got a cup for this. I wonder if anyone ever beat him", Regulus mused.

"No one. The Weasley twins were close though, they had 1378 detentions", answered Harry.

"So it is still in the trophy room?" Regulus asked lackadaisicaly.

"I don't know. Maybe it is..."

"I wish I could see it again", sighed Regulus.

Harry let Regulus spend a few minutes in memory lane, then asked, "Can I ask you about something?"

"Sure. Ask". answered Regulus.

"It is about my father", Harry started.

Regulus' eyebrows rose.

"You see it is kinda stupid. And I asked Sirius and Lupin about this but..."

"You had a trip into a pensieve?" asked Regulus.

"How did you know I did that?" exclaimed Harry.

"I did too. And it was kinda stupid too", answered Regulus.

"Oh! Mind if I ask what you saw?" asked Harry.

"If you really want to know. I saw my father in womens' underwear, putting on his make-up", answered Regulus.

Harry's jaw dropped.

"You're kidding me, right?", Harry said.

"I wish I was. But I really saw this Harry. This is one of my worst memories", Regulus shuddered. "And one of the reasons why I left. I saw this in Christmas break in my seventh year at Hogwarts. I knew James by sight and by his opinions, and I don't think that he did the same thing my father did, did he?"

"No, he didn't", answered a shocked Harry.

"So what's happened?" asked Regulus.

"Well. I fell into Snape's pensieve", Harry started.

"Did you say Snape or have I heard you wrong?"

"Yes Regulus. Snape. He is my potions master at Hogwarts", answered Harry.

"Bet he loves that", Regulus smiled maliciously.

"Do you want to hear what happened?" asked Harry angrily.

"Yep. Go on".

And Harry told him what he saw in Snape's pensieve and what Sirius and Lupin told him. After he ended he stilled and looked at Regulus and said, "And?"

"And what?" asked Regulus.

"About my father?"

Regulus mused.

"Sirius was right Harry. James and Snape really hated each other. And if you asked me which one's House I would have wanted to be in, I would answer you 'with James'. He was a bully when he was fifteen and sixteen but it was only towards Snape, Harry. And Snape, Snape wasn't social. Neither was I, but I didn't carry hatred for the world inside me like Snape did. He spent all his spare time with his nose in Dark Arts and Potions books. He was unpleasant towards everyone, especially girls, worse if that girl was muggleborn. What I could say about Sirius is that he was always a gentlemen around women, even if they didn't belong in the Black family – save Mirzam – that's it. That's why he was 'Hogwarts biggest crush'. And I think that James being a pureblood and in some sorts a gentleman too couldn't stand the fact that someone would insult a woman. So I think that's why this all started. And in the pureblood families, it was a well-known fact that Potters and Snapes hated each other from ages back. On the other hand, Blacks always scorned Snapes about something, what, I'm not sure. According to Snapes, Blacks were always snobbish and more respected in the wizarding world than they should be. So Sirius and James hated Snape and it was a well-known fact that this feeling was mutual", he said.

Harry mused.

"One more question", Harry said.

"Shoot".

"Were you a victim of my father's bullying?" Harry asked.

Regulus shook his head.

"Never", he answered.

Regulus mused for a few seconds, then added "First I never gave him a reason, second even if I did, I think that Sirius forbid him to harm me, after all I was his brother, not James'. So even if I did something that James wouldn't like, it would be Sirius who I would have to talk with. Something else?"

"Are you planning to go back into Mrs. Figg house?" asked Harry.

"Probably not. She is very suspicious. I think I can find a place to hide..." Regulus started but Harry interrupted him.

"What if I took you with me to Hogwarts?" he asked innocently.

Regulus' face lighted.

"Well, students are allowed to have cats", Harry continued. "So do you wanna become my cat, Mr. Black?"

"Gladly, Mr. Potter. But you are going to find another name. Mr. Tibbles sucks."

Harry smirked.

"What about Blacky?" Harry asked.

Regulus rolled his eyes.

"Find something less obvious Potter", Regulus hissed.

"I like Blacky or do you like Pussy?" Harry asked still smirking.

"Blacky. My loss", answered Regulus melodramatically.

"By the way, what you are going to tell the Dursleys?" Regulus added after a few seconds.

"It's easy. We'll say someone 'from my kind' sent you. You are a magical cat and if they don't wanna have a group of wizards on their backs I should keep you" answered Harry smirking.

"In which house are you in?" asked Regulus suddenly.

"Gryffindor", Harry answered.

"Really? Because you sound like a Slytherin", teased Regulus.

Harry growled and threw a pillow in Regulus' direction.

"Oh, shut up, Kitty."
AN: I don't know when I will post next chapter. I have many things on my head this week.
