A certain small redheaded Gryffindor rushed past the trio. Looking at each other shrugging, they were about to head after her when suspiciously a certain blonde Slytherin rounded the corner.

Looking at each other again they headed towards Draco. He was sporting his famous smirk as he and his posse walked to greet them. "What did you do to her?" Ron nearly shouted at him. His face was bright red from his anger. Harry and Hermione stood back ready to back up Ron.

"Me? What makes you think it was me who made your precious little sister cry?" Draco's icy blue eyes sparkled with delight, causing little Gryffindors to cry but getting the golden trio all worked up was a completely different kind of joy for him.

"Who else would find pleasure in torturing my little sis? If it wasn't you, then I know you at least know who it was. Speak now you son of a..." he paused as a teacher walked by, "before I blow your fuckin' head off," he had his wand out ready to fight. Harry took out his wand but wasn't pointing it, while Hermione had her hand in her pocket ready to pull her wand out.

"How about any Slytherin... or anyone with a fuckin' mind or any common sense." he sneered. "So what if I did? What are you going to do about it? You going to let your friends stand up for you as usual? You going to hide behind them like you always do?" Ron turned a brighter shade of red as he brought his wand closer to Draco only to make him laugh.

"Go ahead... try," Draco smirks leaning closer provoking Ron. Hermione nudged Harry whispering something in his ear. Harry then nudged Ron pulling him by his wrist away as Draco and his posse threw insults their way. "What was that about?" Ron asked, "I was about to blow his head off." At this Hermione had to hold back a giggle.

Ron glared at her as she started to explain, "There was this potion I read about... a potion perfect for Malfoy. I've been waiting for a reason to use it on him since last year. It will totally knock him off guard. But I think he is going to expect us to take some sort of revenge I think he knows were planing something. So we will wait a bit, a couple weeks or so."

Ron looked at her still confused till she whispered in her ear. He smiled and looked at Harry who's smile was wider than you would think his mouth could stretch. "Bloody Brilliant..." Ron muttered.

Time passed slowly, Malfoy annoyed and continued to provoke and give reason for Hermione to concoct the special gift for him. The weekend after their plotting Ron and Harry were too anxious to wait. Hermoine sighed as they brought to her attention they wanted to get this done and soon.

"Well then if you all want to so bad you can start gathering ingredients," they all nodded, "we will need 3 ashwinder eggs, bloomslang skin, a sliced caterpillar, 3 daisy roots, a dragon horn (in powder of course), ginger and a powdered moonstone." Hermione looked at their confused faces.

She sighed, "Can you handle that? Should I write it down?" They silently nodded. She took a piece of parchment and wrote it all down.

"Where- Where can we get all this?" Ron asked looking down at the piece of parchment. Hermione sighed.

"Where do you think?"

"I don't know" Harry shrugged

"Your both hopeless."

"We can just pick the daisies right?" Ron said looking at the list.

"No"

"No?" Ron and Harry both said looking back at her.

"Go to the potion store"

"Why can't we pick them?" Ron said thinking it would be easier, plus save on money.

"They are special daisies"

"Are they really?"

"Yes"

"Will it all be at the potions store?"

"Hopefully... if not, you still have your invisibility cloak right Harry?"

"Yeah..."

She smiled and turned on her heels and left. They looked at each other shrugged and walked off to check when the next visit to Hogsmeade is, almost hoping they would run into Draco on the way there.

She pretended she just them get the potion's ingredients because they were annoying but in truth she was just as excited about it. She couldn't wait to get back at Draco to see if the potion worked. It was exciting for her, as was most of school or anything having to do with school. Even if it didn't work right she couldn't wait to see the side effects. You'd think she'd learn after the Polyjuice potion.

The next weekend they took a trip to Hogsmeade. Harry and Ron went to get ingredients as well as hang out while Hermione chose to stay and look for information on her potion. She couldn't find any reports of side effects or any cases where it didn't work right except for one where the person just picked the daisies for their roots and the condition was permanent. She found this wasn't a spell that was not used often so she had a hard time finding much information on it.

Meanwhile in Hogsmeade

"Where's the Potion shop again, Harry?" Ron asked looking at the parchment.

"Not that way," Harry said pulling Ron around a corner. The potions shop was in a far corner of Hogsmeade. It was dark and the windows had black curtains covering them making them wonder if it was open. They quietly pushed the door open. The whole place was lit up by candle light alone. Ron looked at Harry who boldly walked into the shop. The shop keeper wasn't behind the desk which again made them question if they didn't just forget to lock up.

An tall old man with a pointy gray mustache and long black cloak came out from a door behind the desk. "Can I help you?" he asked them. Harry shook his head, "We- were just looking." They looked around, the floor was dusty and you could see where people had stepped. The walls were lined with bottles of everything from toad intestates to daisy roots.

"Looking for what, Mr. Potter, Mr. Weasley?" came a familiar voice. Ron and Harry shuttered as the tall dark figure of their potions professor stepped out from the dark shadows of a corner into the candle light. They looked up at him too afraid to answer while he towered over them. "Where is the 3rd musketeer?" He asked with a sneer. When they didn't answer this either he took a step closer.

Ron stuffed the parchment in his cloak pocket. Professor Snape looked down at Ron then to his pocket, "What are you hiding Mr. Weasley?"

"N- No- nothing Professor..." Ron looked down. Snape put his long boney pale hand out palm up, "Hand it over Mr. Weasley."

"It- It's a note," Harry said, Ron looked at him suspiciously, "from his mother."

"I don't care what it is hand it over," Snape scowled at the 'golden boys'.

"It's just a shopping list," said Ron quickly, still not looking up at him, "for mum."

"Hand it over now!" Snape was getting impatient. What were they hiding. He didn't know but he was sure it wasn't a shopping list for his mom. Ron reluctantly reached in his pocket.

"I swear it's just my mom's shopping list," He pulled out the list and handed it to Snape. Snape looked over the list and double checked it. "Well you won't find a powdered dragon horn here," he stated giving back the list to Ron. "Lord knows why she would need that," he muttered.

Luckily for them the potion wasn't very well known so it passed as a shopping list. "P- Professor do you know where I can-" but Snape was gone. They looked at each other, shrugged and made their way around the store in search of the ingredients.
