Chapter 1

Harry, Ron, Luna, Ginny, Lupin, Tonks, Mad-eye were all gathered around Hermione's bed while Madam Pomfrey healed Neville's nose. She hadn't waked up yet and Madam Pomfrey wouldn't say anything, unless her sister was here. A bang made everybody turn around to the door.

They watched as the hip longed, curly, white and blue haired girl a nose and eyebrow ring walked in, followed by a worried McGonagall and Dumbledore. The scene reminded Harry and Ron, a similar situation, three years ago...

***Flashback***

- What happened to her? – The girl asked. Her hair was white, almost silver and she a nose ring.

- Excuse me, but who are you? – Ron asked.

- I'm her older sister! – She answered rolling her eyes.

- Miss Granger... – Dumbledore started.

- Katherine. – She corrected, through her teeth.

- Katherine. Why don't we sit down? It might be a little shocking... – Dumbledore was cut again.

- I WANT TO KNOW WHAT HAPPENED TO MY SISTER AND I WANT TO KNOW IT NOW! – She shouted at Dumbledore, exploding everything made of glass on the medical wing. Katherine looked shocked, just like Madam Pomfrey, McGonagall and Dumbledore.

- Marvellous... I've never seen anyone losing control of their magic like that inside of Hogwarts... – Professor Dumbledore said amazed.

- How old are you, darling? – McGonagall asked.

- I'm fifteen. What does that have to do with my sister? What happened to her? – She asked.

After explaining Chamber of Secret, fixing the broken things, Dumbledore invited her to attend to Hogwarts, a week later Gryffindor House had a new member.

She was the one who discovered who discovered the paper about the basilisk on Hermione's hand and helped us to close the chamber. She helped us to clean Sirius name, demanding a trial and proving him innocent using Veritaserum. She still had the scar on the right side of her face, very similar with Harry's bolt, but hers went from her forehead down her jaw, that she got at the cemitery helping Harry to runaway from Voldemort.

She graduated the year before with glory and became seeker of the Harpies.

***Flashback***

- What happened? – Kath demanded and after knowing her for three years everybody knew better than discuss with her. Harry started to tell her about his vision of Sirius being tortured by Voldemort at the Department of Mystery, how they went to the Ministry of Magic, how she was hit by a curse, that Sirius was duelling with Bellatriz and that sent him through the veil and that the Minister, finally admitted that Harry and Dumbledore were right about Voldemort.

- This isn't good... – Kath breathed out running her fingers through her head – Sirius is dead? – She asked, with tears in her eyes. We nodded and she breathed out heavily – Oh sweet, come here. – She said, opening her arms to Harry, who hugged her and started sobbing, for the first time since Sirius died. He felt comfortable enough to break down on her arms, just like with Hermione. She rubbed his back, muttering comforting words to him. – How am I supposed to tell Hermione Sirius is gone? – She asked. Hermione and Sirius have been dating along the year. They seemed very in love, even though Molly Weasley strongly disagreed...

***Flashback***

- Hey! – Sirius said, putting two fingers on his lips and whistling, making everyone looks to him – Hermione and I have something to share with you. – Hermione bit her lip, looking over Sirius, who nodded. She took a deep breath.

- Sirius and I are dating. – She said.

Silence.

A dead cold silence.

- That's unacceptable! – Molly shouted – You can't date him, Hermione! He is too old!

- Miss Weasley, while I respect your image and opinion I can make my own decisions. – Hermione said – And I already had too much trouble already convincing Sirius that our age difference doesn't matter, to let anybody's opinion interfere in it.

- But he is too old! You can't date him! Katherine won't allow it, right? – Molly sounded desperate.

- Why are you dating each other? – Katherine asked once Molly was done shouting at them.

- Because I love her and, for some weird reason, she loves me back... – Sirius answered, grabbing Hermione's hand and squeezing it.

- Are you happy? – Katherine asked to Hermione.

- More than ever! – Hermione smiled. Kath nodded, getting up slowly. She stopped in front of Sirius, who gulped. It would be funny to see a 6'5'' man afraid of a 5'3'' woman if the tension wasn't so thick.

- I'm going to say this only one time, so you better listen carefully. – Kath said, deadly calm – You are not to hurt my sister. If you ever hurt her, intentionally, I will hunt you down and rip your head off. With my teeth. Did I make myself clear?

- As water. - Sirius answered.

- Good. Then, you have my blessing. – Katherine said, kissing Sirius cheek and going back to her sit, while Molly muttered about how wrong their relationship was and everybody else congratulated them. After some time Molly came to terms, but still didn't like the situation.

***Flashback***

- It will be hard, but she will be able to get over it... – Ron said, trying to convince himself. Kath shook her head.

- Sirius proposed almost a month ago. She loved him very much. It won't be that easy for her to get over with it.

- I don't think, even if Mr. Black hadn't proposed to, Miss Granger wouldn't be able to get over Mr. Black death that easily. – Madam Pomfrey said.

- What makes you say that? – Harry asked, still hugging Kath.

- I don't think it would be appropriated to tell everyone that.

- They are her friends. They will know, sooner or later. Just say it. – Kath answered.

- Miss Granger is around a month pregnant.

...

- Pregnant? – Minerva was the first to have a reaction.

- Yes.

- Did the curse... ? – Kath stopped herself.

- No. The curse would have made her lose the children, but there was some sort of shield around her belly, that protected them. – Pomfrey explained, easing everybody's mind.

- It was instinctive. Her dream was to be a mother. If she have known she was pregnant she would never have risked her children's life... – Kath looked to Pomfrey – Children. You said children, as in more than one baby. Why would you say children? – Kath asked, panicking.

- She is expecting twins. Pomfrey said. The glasses around the room started to shake, while Kath tried to control her breathing. She pushed Harry away, gently, and walked out the infirmary. A couple of seconds later there was a scream and the noise of glass exploding. A few minutes later she walked back in, with her fist bleeding. She dismissed Madam Pomfrey, sat in a chair by Hermione's side and buried her face on her hands.

- Can somebody tell me how the bloody hell am I suppose to tell my sister that she is pregnant and that the father of her children, the man she loves and was suppose to marry her, is dead? – Kath asked with a broken voice.

- We could offer her to make an... – Dumbledore started, after sometime of silence, but was cut by Kath.

- You better think twice about what you will say because if you finish that sentence with the word abortion I swear on my life I will forget you are Albus Dumbledore and I will rip your tongue out and make you eat it! – She growled, making him shut his mouth.

- I believe I have an idea. – Lupin said, putting his hand on Kath's shoulder, making her look up.
