Grimmauld Place

                                    

                                          
Arabella was launched out of the fireplace into a very old looking empty room. 
"Where am I?" Arabella thought, looking around.
She then heard footsteps coming closer outside the room and the door opened. Arabella thought that she might have gone to the wrong place, but the person who opened the door turned out to just be Abigail.
"You're here! Come here" Abigail smiled. Arabella walked up to her to see that her baby bump had grown quite a bit since Arabella last saw her back in June. 
They walked down a corridor and Abigail opened a door to reveal a long dining table with only a few people sitting at it.
"Ah! Arabella, thank goodness you're safe" Mrs Weasley said, approaching Arabella and hugging her.
Abigail gestured for Arabella to sit in a chair.
After everyone had sat back down, Arabella spoke up.
"I've somehow been expelled again, haven't I?" She asked.
"No, you have only had a warning, seeing as it is your first and hopefully only time you will cast underage magic" Ominis smiled.
"And Harry? This was the second time he 'has' cast underage magic" Arabella asked.
"He has been expelled, but Dumbledore has gone to the Ministry to get them to change their mind" Sirius told her.
A few more moments passed, and Dumbledore opened the door and entered the room.
"What's happened, sir?" Abigail asked.
"They have decided to revise his expulsion and will question him at a hearing on the twelfth of August" Dumbledore said calmly, not looking at Arabella once, however, he gave something to Ominis.
"I think it is time for you to go to bed, dear" Mrs Weasley said, tapping Arabella's shoulder. Arabella nodded and got up and walked out of the room. 
"Upstairs, first room on the left" Mrs Weasley called after her.
Arabella walked up the stairs, the walls were lined with decapitated house elf heads in cases.
She walked more, eventually approaching the door that Ron and Hermione were supposedly in. She opened the door and a pit of arms were immediately flung around her and Arabella's vision was obscured by bushy brown hair.
"Bella! You're here!" Hermione said, pulling away from Arabella.
"Let me breathe, Hermione" Arabella smiled.
"So what is this place?" Arabella asked.
"Headquarters, for the Order of the Phoenix" Ron said.
"What's the Order of the Phoenix?" Arabella asked.
"It's a secret society" Hermione answered. "Dumbledore founded it. It's the people who fought You-Know-Who last time" Hermione continued.
"So what's happening with him? Voldemort, I mean?" Arabella asked.
"We don't know, we're not allowed in the meetings" Ron said.
After a while, Harry came up, and everything that Arabella had asked Harry had also basically asked, but with added shouting from him.
The next day, Arabella woke up, and saw a letter on the table next to her. She sat up and ripped open the envelope.
Dear Arabella Gaunt,
We are pleased to inform you that you have been re-accepted into Hogwarts School of Witchcraft and Wizardry. You will get to the school with the other fifth years, by carriage, as you are still sorted into Slytherin.
Minerva McGonagall
Deputy Headmistress
Arabella smiled, now knowing that (almost) all the problems from the previous year had been fixed.
