The Green Potion

This was definitely the one! I remember putting the concoction into this very bottle.

I pulled away the cork lid and tossed it away. Winking at the crowd before taking a big sip of the potion.

In only a few seconds now I would... Uh Oh...

Barrffff

My stomach contents were emptied onto the floor. That wasn't the right potion.

"Idius," Cho Chang screamed. The crowd didn't understand what was going on.

"I'm fine," I said, "That's just my barf potion." Nobody understood why I would have one of those, but it was imperitive for any good potions master to be able to clear the contents of his stomach in an instant.

My concoction was brilliant.

Barrrffff

I fell to my knees, with chunks of pumpkin falling out my nostrils.

"Are you okay," Screamed Cho Chang? I was fine. This had happened all the time.

"This is just part of the plan my beauty," I said. Man, were my potions brilliant. The crowd didn't even realize how amazing this--

Barrrfff

"Oh shit," I said, "I'm dieing." It was okay, there was only a little blood coming from my ears.

Finally I rolled to my back, dry heaving for a few moments, before I grew silent. And then the darkness came.

"Oh Merlin, he's dead," screamed a hufflepuff. No answer came.

For a few seconds the officials wondered if they should intervene.

I jumped to my feet like a man possessed. Everyone was relieved.

"All good," I said, "the potion is gone from my system." I marked the potion bottle for later use.

Now for the right potion!
