Severus Snape X Reader

1

It was the last year at Hogwarts, y/n confidently entered the train and looked for a free compartment.

- Nothing free... she exclaims
- Only if... no.. but maybe...
She walked a little and swallowed hard, she  felt her  heart beating faster and faster and after a breath of air she entered the teachers' compartment.

-Hello...I didn't find a free compartment, I was wondering..

she doesn't even get to finish the sentence when Professor Lupin says

-Make yourself comfortable, miss y/n

-Thank you!

the girl felt cornered, she feelt like  the air she was breathing wasn't enough

- Are you ready to start  the last year, miss y/n?
Professor McGonagall asks smiling - Yes, all summer I have ..
- ..Read books and learned different spells? Professor Snape interrupts Rudely

-actually..yeah
- to pass the final exams, you need a lot more than knowledge  of magic
Y/n felt like the compartment was getting smaller and smaller. She looked up at Professor Snape, his black eyes  penetrating her, as if he was trying to read her mind

-Oh, Severus, take it easy, y/n is an exceptional student.

- We will see this
. He says in a serious tone. Once again his gaze met y/n's, and a small smile of satisfaction appeared on his lips immediately after y/n moved her eyes to the floor 

A loud sound was heard and the train suddenly stopped with a loud screeching sound, 

-what happens? I'm sure we haven't arrived yet ..says McGonagall

The air was getting cold and the girl's heart was beating faster and  faster.. the lights of the train started to turn off one by one and everything around had started to freeze. It was dark and cold.. She was intrigued and scared at the same time.

-something is moving outside. y/n says worried
-not just outside..says Lupin
-Lumio said Snape and his wand lit up.

He gets up and walks towards the door. Without hesitation, a floating creature entered the compartment, it was scary, its face was covered by a black veil but its claws were very visible

What happens? Who is he looking for? Instantly the creature walked past Snape and walked over to y/n Without having time to react, the dementor  approached her and suddenly the girl felt weak, he was sucking a part of her soul way too fast. All she heard before passing out was "EXPECTO PATRONUM" then black..

-she wakes up...
Says a far too familiar voice. Ron was sitting by her bed along with many other students and teachers.

-Where am I? What happened?
-You've been kissed, MudBlood, Draco said with a laugh.
a slap was heard and y/n noticed that Snape had hit Draco, this brought a small smile to her face.
-You were attacked, Miss y/n, by a.. -Dementor? The girl whispers
-Exactly
-But..they are controlled by the Ministry of Magic, they couldn't have done that if..
-If they hadn't been ordered to do that. Dumbledore said calmly.
-Come on everyone, let's let her rest. After everyone left, y/n fell into a deep and peaceful sleep, but on the other side of the castle, the teachers were meeting to advise each other on what to do. Who had sent the creatures to attack the train? What nightmare awaits them? what threat is coming.. All this had no answer at the moment, but time is the best answer
