Deadly Snake, Silent Dragon.

Petrified

Sorry guys, this is a short chapter.

By next morning, however, the snow that had begun in the night had turned into a blizzard so thick that the last Herbology lesson of the term was canceled.

The castle was darker than it usually was in daytime because of the thick, swirling gray snow at every window.
My lunch was cut off by Alexander Who hurriedly sat next to me.
In the Slytherin table.
Everyone started glaring at us.
I exhaled and cleaned my mouth with a napkin.
"Yes?" I asked him.

"What's a Parselmouth?"
I looked at him weirdly, "No one explained it to you?"
"Some did but you explain it the best" he teased, I chuckled.

"Well" I said straight, "It's some who can speak to any snake, everyone knows that's the mark of a Dark wizard, but you need to have a true Slytherin blood in your system to be able to" I said shrugging.

"Does that make Harry a Slytherin?" He whispered.

"I doubt it" I shrugged, "If he was he would be in my house, not a Gryffindor"

"ATTACK! ATTACK! ANOTHER ATTACK! NO MORTAL OR GHOST IS SAFE! RUN FOR YOUR LIVES! ATTAAAACK!"

That's all it took for us, to hurriedly get up and follow the screams.
Once we got there, Justin and nearly headless Nick were petrified.

Professor McGonagall came running, followed by her own class, one of whom still had black and white striped hair. She used her wand to set off aloud bang, which restored silence, and ordered everyone back into their classes.

I loomed back a little, Casting invisibility spell on me once I was sure no one saw me.

Justin was carried up to the hospital wing by Professor Flitwick and Professor Sinistra of the Astronomy department, but nobody seemed to know what to do for Nearly Headless Nick. In the end, Professor McGonagall conjured a large fan out of thin air, which she gave to Ernie with instructions to waft Nearly Headless Nick up the stairs. This Ernie did, fanning Nick along like a silent black hovercraft. This left Harry and Professor McGonagall alone together.

"This way, Potter," she said.

"Professor," said Harry at once, "I swear I didn't-"

"This is out of my hands, Potter," said Professor McGonagall curtly.

Ivy started following them around a corner and she stopped before a large and extremely ugly stone gargoyle.

"Lemon Drop!" McGonagall said the gargoyle sprang suddenly to life and hopped aside as the wall behind him split in two.
Ivy has never walked to Dumbledore's office, but I guessed it's his office since it was well hidden.
And with that, they walked upstairs.
