"Draco!" A pale Ginny Weasley was shaking him awake. He opened his eyes. She pulled him to his feet. "No more of that fainting business Malfoy it's a little dramatic even for you." He grimaced a smile at her attempt to cheer him up. Madam Pomfrey came out from her office and made her way over to them. "She was hit with an eradicus spell. It attempts to eradicate the person as quickly as possible. There is only one cure and it is a very complicated potion that is administered and then an even more complicated spell has to be performed by a great witch or wizard.
"Well I for one, refuse to take those odds. There has to be something we can do to improve that number. We can help you take care of her, strength in numbers can make a stronger spell." Ginny stared defiantly at the nurse. "It's very complicated but you're all quite powerful so it shouldn't be too much of an issue." She responded. "The spell to reverse it is relinquere and the wand movement is like so." She moved her wand in an intricate design.
Draco immediately started practicing the wand movement as everyone else nodded. "You'll have to practice somehow and be able to observe the results." Harry nodded. "The room of requirement can help us with that." Madam Pomfrey shook her head. "You certainly are James Potter's son." He gave a half-hearted grin.
"But what about the potion?" Harry asked. Leave that to Professor Slughorn, Professor Sprout and me. Now you better start practicing, it is quite hard. They all stood up except for Draco who was clutching one of Hermione's hands. "C'mon mate. This is the only way to save her." Blaise reasoned.
He nodded and allowed himself to be taken to the room of requirement. He walked by the tapestry and the door appeared immediately, sensing his distress. Even in his state of shock he stopped for a moment to admire the magic of the room. It had lifelike dummies ready with monitoring spells showing all of their vitals as well as books on how to cast severely complex spells and how to get hard wand movements correct as well as an entire book dedicated to the actual spell.
Ginny walked up to a dummy and touched its face, recoiling in disgust. "It feels just like skin!" she exclaimed. "Hey guys," Harry started, "I think Ron should be here to help. It wouldn't hurt to have an extra person perform the spell and Hermione's his best friend too." The question was addressed to the group but Draco knew it was meant for him.
"Yeah. He should be here too." He replied, knowing it's what Hermione would have wanted. Harry beamed. "I guess I'll send him an owl." Blaise looked at the ex-Gryffindor incredulously. "That would take much too long, we need to start working on this spell as soon as possible!" Harry glared at the Italian. "Well then what do you suggest Zabini?" Blaise raised an eyebrow at the use of last name and decided to let it slide. "How about you wish for him, y'know, since we're in the room of requirement."
"Oh yeah." He closed his eyes and a moment later a very astonished looking Ronald Weasley was standing beside him. "Bloody hell. What just happened? Are we in the room of requirement? What's going on?"
Draco sighed, knowing he would have to recount what happened. "Hermione and I were attacked by my father. He and I were dueling and he sent a terrible spell at me but Hermione jumped in front of me, taking the spell instead. I killed my father and phoned the aurors. The Minister took care of everything; he didn't charge me and left Harry so he could be there with Mione. Madame Pomfrey figured out that my father used the eradicus spell and told us that Mione has a…. twelve percent chance of living. Ginny demanded we be able to help save her. Madame Pomfrey, Professor Slughorn, and Professor Sprout will be making the antidote potion while we learn the proper counter curse to save her, which brings us here."
Ron nodded. "We better get to it then. What's the counter curse and wand movement?" "Relinquere." Luna informed him. "And the wand movement is like so." She demonstrated and his eyes widened slightly but he took on a look of determination. While Draco had been informing Ron of the situation, Harry had picked up the book on the relinquere spell and started reading it.
"So who wants to try first? Draco?" Ginny suggested. I nodded and walked up to a dummy. "Relinquere!" I performed the wand movement. The dummy's heart rate went up a little and it's eyes flickered open for a second. Harry grinned. "According to the book that's what's supposed to happen when only one person performs the spell. Looks like Draco's mastered it."
Draco grinned a bit. If…no when Mione woke up he knew she would be proud he got such a complicated spell right on the first try. He spoke up. "How about everyone gives it a first try and then we'll figure out how to help the people who can't get it right away." "Sounds like a plan to me mate." Blaise answered.
Ginny stepped forward. "Relinquere!" She grinned as the dummy responded. "Looks like two of us have it." "I'll go next." Harry offered. "Relinquere!" His dummy's heart rate increased but the eyes stayed shut. "Almost mate." Ron said as he stepped up to a dummy. "Relinquere!" He gained the same results as Harry, as did Blaise. Luna went last and the heart rate barely increased at all, but it increased enough to make a difference.
Draco and Ginny began helping the other four. For Harry, Ron, and Blaise it was a matter of practicing. For Luna, however, it was the wand movement that was bothering her. She couldn't seem to get it right. So Draco took her and began to help her learn it. Ginny took the other three and told them to read the book on the spell which would teach them about the feeling involved with the incantation. Then she moved back to the dummy side and continued practicing to make sure her success was not a one-time thing. Draco soon joined her, leaving Luna to practice the wand movement alone.
They went to bed late that night seeing as everyone but Harry and Ron still had classes. The aurors in training would stay in the room of requirement all day practicing and the other four agreed to come whenever they had free time, the Head Boy promising to switch around the prefect schedules so he no longer had to patrol. This went on for two months until everyone could finally perform the spell.
They all trooped to the room of requirement for one last time to practice the spell altogether. They stood there nervously. "Alright let's do this." Draco said. All six of them levelled their wands at the same dummy, mentally preparing themselves. Draco squared his shoulders. "Three, two, one" "Relinquere!" They all chorused. The spell took immediate effect. The dummy's heart rate increased and it's eyes opened wide and stayed that way.
They all cheered. "Let's go tell Madame Pomfrey, maybe the potion will be ready by now. Draco smiled to himself. We're coming to save you Mione. The three Gryffindors, two Slytherins and Ravenclaw dashed to the Hospital Wing.
"Madame Pomfrey!" Ginny exclaimed, out of breath. "We've done it!" She smiled. "Just in time too, the potion is ready. We can reverse this spell right now." She grabbed a vial of potion and they gathered around her bed, wands ready. Draco took a breath, steadying his nerves and hand. This was the moment of truth. Madame Pomfrey brought him back to reality.
"Now the moment I administer the potion you must cast the spell. On my count. Three, two, one". She shoved the potion down Hermione's throat and moved out of the way immediately. "Relinquere!" She started breathing and a tear ran down my cheek. Her eyes fluttered open. "Mione?"
