Okay I'm just changing EVERYTHING ENJOY

Skipping to August's full moon, enjoy that jump though

"Erin-" Remus said, practically cornering her in the kitchen almost three weeks later. It was the day of full moon, and Remus had been able to have Wolfsbane, because of the day when Tonks had become Bellatrix. They had bought a few months of supplies from Diagon Alley, because they definitely were right when they had said that no one would question Bellatrix.

"Yes, I know!" Erin snapped. "Make sure Harry and Hermione stay here, I got it!"

"No, that's not what I was going ask." Remus said.

"Oh?" Erin asked, raising an eyebrow.

"Sirius is coming with me tonight-"

"I know."

"-and I'm concerned about Dora."

"Why?" Erin asked.

Remus sighed. "She's been acting strange. The baby hasn't moved much today-"

"I thought the baby barely moved on full moons anyway?" Erin asked, narrowing her eyes. "Why does it worry you now?"

"Just- can you keep an eye on her? Please?"

"Ah, Hell, I'm already babysitting two- let's make it four." Erin said. "You know she'll call you a prat-"

Remus shrugged. "Thank you, Erin."

Harry and Hermione were pouring over books on the floor in the corner of the living room, and Tonks was leaning back on the couch, her feet stretched out on the table, also reading.

"I thought Sirius didn't like the idea of feet on tables-" Erin began, poking one of Tonks' feet as she walked by.

"Sirius was also raised by two incestuous lunatics, his opinion doesn't matter much." Tonks replied, not even looking up.

Erin flopped down onto the couch. "This is what we're reduced to?" Erin asked. "Three bookworms?"

"Could be four, find yourself a book." Tonks responded.

Erin scoffed.

"What are you doing, anyway? I thought you were going with them?" Tonks asked.

"I've been asked to babysit." Erin said. "Those two-" She pointed at Harry and Hermione. "-and you two." She finished, pointing at Tonks.

"Why? What on Earth are we going to do?" Tonks asked.

"Sirius expects Harry and Hermione to run, and Remus expects you to have the baby."

"Right." Tonks said slowly. "Because we're just planning for everything to happen while they're gone."

Erin smirked. "What are you two reading anyway? We know you're not studying for your NEWTs-"

"What do you two know about Horcruxes?" Hermione asked, turning to face them.

Tonks placed her book on her belly, frowning. "Horcruxes?" She asked. "Those are really dark-"

"But what do you know about them?" Hermione prompted.

Erin and Tonks exchanged a glance.

"You aren't trying to make one, are you?" Erin asked, slowly.

"No!" Harry said quickly. "No, we're- well, what do you guys know?"

"I just know they're dark magic." Tonks said.

"Same, never heard much about them." Erin said. "Except apparently there's a really bad ritual that goes into creating them-"

"But what about destroying them?" Hermione asked.

Erin shrugged. "I don't know, maybe you can't."

Harry and Hermione exchanged a look.

"Why, though? Of all things to be researching, why Horcruxes?" Erin asked.

There was a sudden sound like howling wind, growing louder every second. They small group looked up at the sound of a loud bang upstairs. Erin moved first, grabbing the Invisibility Cloak from the table beside Tonks' feet and throwing it at the pair in the corner. She stood, her wand in her hand, waiting. Tonks rose slowly too, grabbing her wand from the arm of couch.

Erin gave her a look. "You're not dueling-"

"Where else am I going to go?" Tonks spat.

There was the sound of footsteps in the upper hallway, and on the stairs.

''I really never realised how loud those stupid stairs are." Erin whispered, waving her wand and turning out all of the lights in the living room.

A minute later, though, they turned back on.

"Hello, lovelies." Bellatrix greeted, a wicked smile spreading across her face. Rodolphus Lestrange stood next to her, grinning just as madly.

Short chapter, and I'm sorry!
