Prompt: Hermione preparing a potion whilst humming "bubble, bubble, toil and trouble…" and Snape going off on a rant of all the things that are incorrect, and what catastrophes would happen if you "boil and bake; Eye of newt, and toe of frog" etc. :)

I own none of the characters of JK Rowling. Verse from Macbeth Act IV, Scene I.

Hermione Granger now apprentice to Severus Snape for the past two years stood at a large cauldron brewing pepper up potion for the coming school year. She was more than happy to after realizing Severus and Severus alone brewed all the potions in the infirmary. So there she stood turning the correct number of times bored out of her mind and then Macbeth.

"In the poison'd entrails throw

Toad, that under cold stone,

Days and nights has thirty-one;

Swelter'd venom sleeping got,

Boil thou first i' the charmed pot!"

She said with a smile on her face. So she continued on.

"Double, double toil and trouble;

Fire burn, and caldron bubble."

And as best she could she did the typical witch's cackle.

"Fillet of a fenny snake,

In the caldron boil and bake;

Eye of newt, and toe of frog,

Wool of bat, and tongue of dog,

Adder's fork, and blind-worm's sting,

Lizard's leg, and owlet's wing,

For a charm of powerful trouble,

Like a hell-broth boil and bubble.

Double, double toil and trouble;

Fire burn, and caldron bubble."

Hermione finished stirring and sat on a stool near the cauldron while she massaged her fingers.

"Scale of dragon; tooth of wolf;

Witches' mummy; maw and gulf

Of the ravin'd salt-sea shark;

Root of hemlock digg'd I the dark;

Liver of blaspheming Jew;

Gall of goat, and slips of yew

Sliver'd in the moon's eclipse;

Nose of Turk, and Tartar's lips;

Finger of birth-strangled babe

Ditch-deliver'd by a drab,

Make the gruel thick and slab:

Add thereto a tiger's chaudron,

For the ingredients of our caldron"

Unbeknownst to Hermione Severus was standing a few feet behind her listening. He was surprised by the menacing voice coming from the young woman. Though he knew the passage quit well. For those muggles who never came in contact with the wizarding world this was their idea of what witches did. But he waited for her to finish.

"Double, double toil and trouble;

Fire burn, and caldron bubble.

Cool it with a baboon's blood,

Then the charm is firm and good."

She had finished and did the cackle again sending shivers down Severus spine. That cackle sounded to familiar for him to take it lightly. Nonetheless it was time to take her out of her reverie.

"That is the most inaccurate drabble I've ever heard." Bellowed Severus as he came around Hermione. She had jumped slightly, much to his chagrin he was hoping for her to jump, maybe even squeal. "Most of those ingredients are forbidden. Nose of Turk and tartar's lips. What a lode of shite." He mumbled as he put away some of the ingredients he just bought for his personal stores. Hermione sat and watched the potions master as he grumbled.

"Fillet of fenny snake would be hard to come by even now and you can not bake in a cauldron. Eye of newt and toe of frog combined with an adders forked tongue would instantly kill the brewer, as the bloody thing would cause an explosion. And as for the scale of Dragon and tooth of wolf…" Severus didn't continue loud enough for Hermione to hear but she stood there smiling at him. He was genuinely angry. "Why are you saying such asinine things anyway? You should know better?"

"Severus you do know it's from Macbeth…it's not real?" He stood there a moment. "Written by Shakespeare." For a moment Severus blushed but his normal pallor returned.

"You know he was a wizard?" he said as he walked by her and out of the lab.
