Summary: Bella was left alone in the forest, however she never told Edward, or any of the Cullen's that she was not Bella Swan – Chief Police Swan's daughter. Instead she is Isabella Snape, a sister to the most hated teacher at Hogwarts School of witchcraft and wizardry, a witch and an unofficial Marauder. What happens when Professor Dumbledore invites the Cullen's to Hogwarts to help protect the school? Will there be chaos? Or will there be love?

Disclaimer: I do not own Twilight, Harry Potter or other things that may appear in this story, if you see something familiar; it's probably not mine. I do, however, own this plot and possible new characters.

A/N: You guys hate me don't you? I am so sorry, I was busy, and then when I wasn't busy, I had no inspiration. Fortunately, I do have a rough outline of what I want to happen with this story, so hopefully I will be able to work faster. Unfortunately, it will have to wait for a bit as I am in the process of moving house and that is going to be a little stressful. So please forgive me, and sorry for this chapter.

Chapter 36

Bella had escaped the fireplace in a huff. She needed to find her boyfriend. She bypassed all the other rooms, instead, she moved towards the room he always seemed to be in if he wanted to be alone, or think, and after the week he has had, she wasn't surprised. But they needed to talk, now, before she lost the Gryffindor courage she had been able to gather.

"Sirius Orion Black, we need to talk," Bella managed to spit out when she noticed the back of her boyfriend.

"That's never a good line," Sirius replied, he refused to look at her, instead he continued to focus on act of feeding the hippogriff in front of him, "did I do something wrong?"

"Yes... well... no," she stumbled over her words as her nerves began to take over.

"Which one is it?" he let out a sarcastic laugh.

"It's more of what we have both done... or rather, what we haven't done,"

"You've lost me Bells," when he finally turned to her she could tell that he was uncomfortable. In every emotional time when they were growing up, Sirius would always be the first one out the door. But now, he just leaned on the wall, and slid down till he was on the floor.

Bella let out a sigh before she followed his actions, "We don't talk Sirius – don't look at me like that – you know what I mean, we don't talk about all that shite that matters. I'm not the only one that noticed, Remus was the one that told me to talk to you, if he hadn't we would be doing the same thing that we normally do, keep putting it off until something happens and then we ruin everything."

He let out a sigh, but grabbed her hand, intertwining his fingers with hers. They were quiet for couple of minutes before he let out another loud sigh, "I know Bella. I know, you know how hard it is for me to open up. But I promise, I'm going to try, because this," he waved their laced hands to show what he was talking about, "it's real, and I don't want to mess it up because I was being..." he struggled for the right word.

"You?' Bella supplied with a laugh.

His laugh joined hers, "Yes, because I was being me,"

For the next few hours, they sat there, occasionally throwing a dead pheasant to Buckbeak, talking about everything they could think of.

Christmas Eve

"Hey Harry, how's it going?" Bella asked as she closed the door to his room. Harry had isolated himself since he had seen Mr Weasley getting attacked. He hadn't bothered to interact with anyone, deciding to not answer any of the questions thrown at him through the door. "Harry, you can't blame yourself for what happened with –"

"You don't understand Bella. It wasn't just that I saw him. I was the one attackin –"

"No, Harry, you weren't the one that attacked him. If anything, you saved him, if you hadn't seen it, it would have been much worse. But we're going to get through this Harry, I promise you that. When we get back, I'm going to start teaching you something called Occlumency, the act of shielding your mind from mental attacks. Dumbledore thinks that you and Voldemort forged some sort of link when he tried to kill you when you were a baby, so maybe this will help," she pulled him into a hug which he accepted, "we will get through this, I promise,"

They stayed in that position until they heard a knock at the door. The person entered without waiting for an answer Harry saw his godfather stuck his head through the door. "Everything okay in here?" he asked tentatively.

"Yeah Sirius, everything's fine," Harry mumbled gruffly and motioned him in with a jerk of his head.

"So what are we talking about?" Sirius asked as he joined the two who sat on the bed.

"Anything but what happened the other day," Harry said before Bella could say something.

The couple exchanged looks over Harry's head, which he had leaned on his godmother's shoulder, "Um, okay," Sirius muttered, "How about we talk about whatever is happening between you and a certain Luna Lovegood?"

Harry blushed, and moved to hide his head in Bella's jacket before he muttered something along the lines of, "I have no idea what you're talking about,"

The couple laughed at the uncomfortable teenager. "Come on Harry, you can't really expect us to believe that?" The blush on the teenager's cheeks said it all, "Really? Even Sirius saw it, and he is the most oblivious person ever," She shushed the ex-convict when he let out a sound in protest, "Come on, cub," she continued, adopting Remus' nickname for the teenager, "tell us what's wrong,"

"She makes me happy," Harry finally said, his face still hidden in Bella's jacket, "but something bad always happens whenever I am happy. It's not fair."

Bella could feel the tears through her jacket. She automatically wrapped her arms around the young boy, Sirius following her lead and winding his arms around his small family.

"Harry," Sirius started softly, "you of all people deserve to be happy. And if Luna is what makes you happy, you go for it, because those people come very rarely," Sirius and Bella exchanged a happy smile over the teenagers head, "But you can't just sit there hoping that she will come to you, you have to go get her. Show her that you care. Then, everything will fall into place," Sirius pulled back enough to stare into the green eyes of his godson, "and if she is the one for you, then, no matter what happens, she will accept you for all your faults, and everything you have gone through, and everything you will go through. Understand?"

Harry just nodded with a calculating look on his face, before he suddenly smiled, "Thanks guys," he muttered, pulling the couple into another hug, "I'm just going to go and –"

Before he could say anything, the door slammed open, hitting the wall with a loud 'thump'. Bella only saw a flash of pink before being tackled into a hug, "BELLA!" Tonks screamed into her ear, "WE KISSED AND HE SAID YES AND OH, HOLD ME, I THINK I HAVE DIED AND GONE TO HEAVEN!"

Sirius let out an awkward laugh, before getting off of the bed and pushing his godson out the door with him. Bella let out a sigh, it was going to be a long (and slightly awkward) girl talk about two of her best friends.

It had been hours before Tonks finally let the Hogwarts teacher go, and without a second thought, Bella made her way purposefully into the kitchen where she knew the headmaster was currently residing. Her easy smile, falling off her face as she noted the signature bright robes of the elder wizard, "Albus," she stated calmly, staring into the twinkling eyes of her employer, "we have to tell Harry everything," she noticed, with some sick satisfaction, that the twinkle died down a little.
