"Oh Merlin, Godric, Helga, Rowena and Salazaar."

"FREDERICK AND GEORGE WEASLEY! WHERE HAVE YOU BEEN?! HOW DARE YOU LEAVE THIS HOUSE! DO YOU KNOW HOW WORRIED I WAS?! YOU TWO WILL BE THE DEATH OF ME, I SWEAR ON MY LIFE!"

Fred had been able to take shelter behind Blair, but George hadn't been so lucky. When they stepped out of the field surrounding The Burrow, they believed that they might actually be greeted warmly by Molly. It was a cold day and the three were dying to collapse in front of the fireplace while being surrounded by the secure and safe walls of the Weasley home. They had been surprised that Molly hadn't rushed out the door as soon as they broke through the tall grass and were in sight of the windows and thought they actually had gotten away with leaving only a note on their departure. But then they dared to collapse on the sofa in the living room just as Molly appeared at the bottom of the staircase.

From then on, she blew up like one of Seamus Finnigan's many potions. Fred, George and Blair jumped up from the sofa after sinking into its cushions with a sigh, but tried to hold in their groans of having to stand once more. Molly had been able to grab hold of George, as he was closest to her, and laid her slaps and punches into his arm. She was near hysterical at the sight of Fred's bruised nose bridge but didn't let herself fall into tears. Instead, she let her anger out on her son's arm while Fred cowered behind Blair's small frame.

"M-Mum, please! We're sorry!" George hid his face in his arms. "We're back, though! Isn't that great?!"

"Where on earth did you go?! How dare you leave without telling me beforehand! The Order were furious!" Molly continued to yell but halted her assault on George's bicep. Her head whipped in Blair and Fred's direction, making Fred shrink further behind Blair's shoulders and the girl wince in fear.

"I-It was my decision, Molly. I wanted to search for things that belonged to my father. The boys wanted to come so I wouldn't be on my own. I know it was spontaneous and dangerous, but I knew what I was doing. Sort of," she trailed off and started fiddling with her fingers nervously. Molly's stare was intense and reminded Blair strongly of Ginny whenever Ron would open his mouth and say something idiotic. She certainly knew now where she had gotten it from.

"What was it you were searching for, then? It had better been worthwhile," the woman put her hands to her hips and narrowed her eyes at the three who huddled together. Blair reached into her backpack that she slipped off her shoulder and pulled out the photo album and the green notebook from one of its large pockets. She held out the green book for Molly to take and watched cautiously as the woman took it from her hands.

"This was your father's?" she questioned and Blair nodded.

Molly turned the book over and looked over the engravings on the front and back. She didn't open to the pages, just simply stared at the shining metallic that Blair had found fascinating. Blair glanced towards the twins beside her and saw they were eyeing their mother with the same look as her. She looked to be studying the engravings intently and letting her eyes follow the swirls that covered the forest green leather. It was as if she recognised the book from the way she ran her thumb over the black pattern.

"Are you absolutely sure this was your father's book?" Molly asked again. Blair's eyebrows pinched together in confusion and she suddenly doubted herself.

"We found it with his potion stuff in the loft of Blair's old house," George explained. This made Molly hum and she passed it back to Blair, her face thoughtful and full of purpose. Blair took it carefully from her and looked to George with a worried expression. Had she been the one to finally break Molly Weasley?

The Weasley mother turned away from the three and headed towards where they thought she kept all her cleaning supplies. The door was built into the side of the staircase and had a tiny golden door handle that Molly pulled open with a jiggle of the hinges. There was a rustle of things as her top half disappeared into the room and left her legs in the view of the three who were thoroughly confused. Fred and George had never somehow rummaged through that particular room, which was saying something. They spent most of their childhood hiding in rooms while waiting for their pranks to be set off by one of their poor siblings. They questioned why they had never thought to scope out the cupboard under the stairs.

Molly's red hair appeared once more as she stood up straight and shut the door after her rummage. In her hands was now a burgundy, leather book that was battered and had its edges scuffed from excessive use. The three watched as she then turned it around for them to see, but it only confused them further.

"Why do you have the same one?" Fred asked, now questioning whether his own mother was a Death Eater after all this time. The book in her hands, was an exact replica of the one Blair held in her hands. Only this one was red and aged, possibly second hand.

"Everyone did. It was our advanced potion making book in our seventh year at Hogwarts," Molly answered. The black swirls were exactly the same and were catching the same light as the green one did to make it reflect on to the walls around them.

Blair finally decided to look at what was on the inside of her father's book. Pulling back the thick cover, she was greeted with printed paper that was worn and stained yellow from the wares of time. The first page began with the title 'Advanced Potion Making for the most skilled of witches and wizards: by Arsenius Jigger.' Besides the stains of what could have been failed potions or Butterbeer, was tiny black hand writing. She inched her eyes closer to the page and saw the words 'This book belongs to Evan Rosier'.

"We did all of that for a bloody potions textbook?!" Fred cried.

"Wait wait wait," Blair stopped him, flicking through the pages and finding not only potion recipes, but what seemed like countless notes from her father on how to improve them. "This is it. It's got to be."

"Your father must have been in one of the years above mine at school," Molly explained. "They updated the potions textbook once I got to my seventh year. My parents were put out by it because I couldn't have one of my older brothers' as a hand-me-down."

"You don't remember him?" Blair mumbled as she glanced up from the pages.

"No. The Slytherins were awful and we'd do our best to avoid them at all costs."

As Blair continued through the textbook, she uncovered more and more notes that had been hand written by her father. The ink had somehow stayed pristine in the aging book and crossed out many things that were in the original recipes. Numbers had been changed and amounts of things had been added and subtracted, somehow making the potion better than the original. But towards the end of the book was where it got interesting. The few blank pages that had been left by the original author were filled with solely Evan Rosier's writing. Whole new recipes had been written out bit by bit with ingredients, methods and explanations of everything you could ever need to brew a potion. Blair had never even heard of the titles before and she believed that these potions had not existed until now. But these potions, although new and personal to her father, were much darker and deadlier than the ones printed by Arsenius Jigger.

"Gosh," she said aloud, making the Weasleys turn to her.

"What is it?" George inquired.

"There's a recipe for an organ crushing potion in here," she gulped, flipping through the truly evil pages. "One to take blood from someone else. One to turn someone into dust. These are awful."

"No wonder You Know Who wanted it so desperately," Molly mentioned as she put her own school textbook down on the coffee table next to her. "But those aren't necessary unique potions. They can be made by using bases of other potion recipes."

"There must be more in there. One that would make You Know Who's army indestructible," Fred thought aloud.

Just as Fred closed his mouth, Blair turned to the last page of the book. The title across the top was what first caught her attention. In her father's hand writing was the words 'Life-replenishing potion' before a list of ingredients that were all too familiar to her. The entire list of her personal healing potion was written in ink before three more were attached to the end. A step by step method was then written underneath before a brief description sat at the bottom of the page.

'Potion heals all physical injuries. Heart is jump started by crushed bezoar and brain is reformed from damage.'

"Well? Is there a miracle potion in there?"

Blair swallowed dryly before lifting her head from the book, her eyes seeing Molly in front of her but looking through her due to the immense shock. Fred and George glanced at each other over the girl's head before looking down at the book that sat limply in her hands. They couldn't see the writing, but could see that it was hand written and created by Blair's father. Molly waited and eventually chose to take the textbook back into her own hands to look for herself. Blair's fingers barely held on as it was taken from her and Molly turned it around to read what had shocked the girl so much.

"Oh my word," she muttered, eyes drifting across the page at lightning speed.

"What is it?" George asked again.

"It's..." Blair started and swallowed, gathering her voice in her throat. "It's a healing potion."

"Cool?" Fred said in the form of a confused question. It didn't sound very shocking to him.

"No," she shook her head, sighing in frustration. She pushed away the shock for a moment and turned to the twins. "It's my healing potion. The one I made! But he's added it to it. My dad created a liquid resurrection stone!"

"A liquid resurrection..." George repeated in a mumble, before his eyes turned into dinner plates. Molly, Blair and George stared in shock at each other while Fred looked between them still in confusion. He obviously didn't remember the reference he himself had made only a week ago.

"What?"

George rolled his eyes and took the book from his mother's hands, holding it open for Fred to see. He squinted down at it for a moment before mirroring his brother's expression, only his jaw was hanging open like something had come unhinged in it. The method was long and the ingredients would be difficult to find, but not impossible. The potion was certainly brew-able and with Blair on their side, she could bring it to life within the next few months.

"This is what your father was going to make?!" Fred cried while pointing a finger at the page. "That's brilliant! Evil, but brilliant!"

"You could bring anyone back from the dead. You Know Who could bring back everyone that was once powerful. You could bring back Dumbledore, Blair!" George ranted with his hands in his hair and looking at her with a mixture of fear and amazement.

"I-I don't think to that extent," she mumbled as she looked over the page once more. "I think it can only work on someone how hasn't long been dead. It says it heals injuries and jump starts the heart. If someone's been dead for a week or two, there's no way the body could function in the way it once did. They'd be like an Inferi."

The three shivered at the mention. Inferius were dead bodies that had been resurrected through a dark spell only few deranged witches and wizards knew. You Know Who was sure to have these already, but resurrecting those who were once loyal and powerful back to their full strength would impact greatly for both sides of the war. Blair suspected that only those who had been dead for a few hours would be able to live again. And if she was as great of a potioneer as her father once was and that the potion actually worked, she could bring back anyone who they'd recently lost.

"Do you think you can make it, Blair?" Molly asked, drawing all eyes to the girl who stood with the book in her hands.

"I-It'll take a few months. Some of this stuff has to mature before you mix it but... yeah. I can make it."
