The next day, Harry told all of his friends about talking to the snake in the girls bathroom. At first, they - especially Hermione - admonished him for talking to a being he couldn't see. However, Harry soon reiterated what the snake said, on how her master was inside of another student, and that it was a he.

"Harry, there might be a way to find out if it's Malfoy or not. But, it is highly dangerous, and could get us expelled if we're caught," Hermione explained.

"What is it?" asked Ron, curious to what Hermione thought.

"Polyjuice Potion. It's a dangerous potion that needs a high skill set, the only problem: it takes a month to brew. And the ingredients will be hard to come by. I found it when I was doing a bit of light reading!" Hermione offered.

"How come everything you learn from some 'light reading' eventually helps us in some way?" inquired Ron.

Hermione, offered no reply, instead just choosing to shrug her shoulders. She then rushed up to her dormitory, and soon brought back down an old and worn book titled 'Most Potent Potions: Year seven.'

She quickly skimmed through the table of contents, before turning to the appropriate page. Hermione set the book down gingerly on the table, pushing it closer to Harry and Ron.

"I took the liberty to scour Snapes supply closet, and he has everything that we would need."

"So, we only need a place to brew it… Hermione, you said that the loo I talked to Rowena in was off-limits right? Maybe we should brew it there?" asked Harry.

"You want us to hang out in a girls loo for the next month?" sputtered Ron.

"It sounds perfect to me!" replied Hermione.

~oOoOoOo~

The Trio didn't get a chance to fully set up the cauldron and it's supplies till later that week. However, Hermione soon had everything set up and she was finishing off the first few steps of the long potion before setting it on a low simmer.

"Okay, there's that. Well have to come by once a day and stir it counter-clockwise for thirty minutes for a week. Then, we'll have to add the boomslang skin, before stirring clockwise for 30 stirs. Then we have to let it simmer for another week. The last week we will need to add the rest and stir it a few times everyday for seven days," rambled Hermione.

"Harry?"

"Guys, I heard Rowena! She's here," said Harry before slipping into Parseltongue to speak to the snake. "It's just me and my friends here! How are you"

"You are kind Harry, have you found my false master yet?"

"Er- No, not yet, sorry. But we are working on it! We have a potion brewing that will let us find whoever it is!"

"The scent it strong, I smell it…" replied Rowena.

"I promise we will find who is hurting you, Rowena," offered Harry.

~oOoOoOo~

The next four weeks passed by quickly, and soon, the Polyjuice Potion was complete. The only thing left to do was decide who they were going to be impersonating, and then to follow through with their plan over the Christmas Holidays.

They figured then would be easier, since most of the students would be going home, even though Draco, Crabbe, Goyle, and Pansy decided to stay at Hogwarts.

Harry, Ron, Ginny, and Hermione were the only ones who stayed out of their group of friends as well. But, they figured they could get away from Ginny quickly enough. They knew it was mean, but the less people who knew about their plan for now was the best in their eyes.

However, the more they thought about it, they realized they hadn't been seeing much of Ginny at all. Ron, who wasn't that worried, eventually made Harry and Hermione realize that she was probably just getting used to the castle, and giving Luna and Neville some space.

They all did feel bad about not realizing it sooner, Since they've been at Hogwarts for over four months now. But, once they figured out who the Heir was, they all promised to spend more time with their other three friends.

Nevertheless, they could worry about it after their job was done, they still needed to get the hairs of who they were going to be impersonating. Which they planned to do after dinner that night, before heading down to the dungeons themselves and finding out the answers they needed.

Hermione had gathered some sweet cakes from lunch, and slipped some dreamless sleep potion into them. Now, all they had to wait for was when Crabbe and Goyle came by after the rest of the Slytherins, and lay their trap.

Hermione however, would have a harder time of getting Pansy away from the rest of the group, and planned to lure her away by confounding her, and slipping her in a broom closet first.

She had to be more careful and precise, and make sure the rest of the Slytherins didn't see her, or realize that Pansy was acting off for a few moments.

So, when they were down in the Great Hall, they hurriedly ate their dinner and slipped off the benches and laid in wait in the Entrance Hall.

Harry and Ron stayed in the shadows against the far wall, under some of the staircases, while Hermione stood behind the statue that dominated the area.

Luckily for her, when the small group of Slytherins came out, Pansy announced she was going to slip into the loo, and she would meet them down in the dungeons in a bit. Hermione pounced as the opportunity, and quickly rushed after Pansy.

After Hermione chased after Pansy, Crabbe and Goyle left the Great Hall themselves, and Harry quickly levitated the two chocolate cakes in the air in front of the statue. He hoped they would notice them quickly.

It seemed fate was on their side when Goyle quickly noticed them, and nudged Crabbe with his elbow - which was a hard feat, considering both of their arms were laden down with sweets.

Showing their gluttony, the two boys quickly rushed to the two floating desserts, and instead of plucking them out of the air, they both opened their mouths wide, and clamped their mouth shut.

It didn't take long before the potion kicked in, and the two large boys fell to the ground in a thud. Seeking their chance, Harry and Ron lugged both boys into a hidden closet, before plucking a few clumps of their hairs, and shutting the door behind them.

Hermione soon appeared with her own clump of hair from Pansy in hand, and noticed that the boys were already finished with their task.

The small Trio soon rushed off the unused girls loo, preparing themselves to drink the Polyjuice and head down to the Dungeons themselves.
