The next day all the classes were cancelled, instead we all were being taught how to cast a Patronus. Thanks to Harry and the DA classes that I already knew spend some time reading and thinking about my next how to cast one and thus I didn't join the classes, rather I went to the courtyard to spend some time reading and planning steps. 

There were some other students too, a group of Gryffindor and Ravenclaw girls, a bunch of Hufflepuff boys, and then there was Tom and his gang. A professor came to courtyard to take all the students back to their classes. The Griffindor, Ravenclaws and Hufflepuffs went away; then he approached Tom and his group, all the boys went back to class but Tom said surroundings started to become cold... A DEMENTOR! I looked up. Not just a dementor, it's almost FIVE something to the Professor and he sorrowed and left. Now it was only me and Tom in the courtyard. I once again started concentrating on my book. All of a sudden the DEMENTORS! And they were all coming towards Tom!! "TOM MOVE!!" I shouted.

But that dumbass has the audacity to take out his wand and fight them even tho he knows that he can't cast a Patronus. If he is trying to Avada Kadavra those soul eating creatures then I guess I need to save him. I threw my stuffs that were on my lap and ran to him. Now it was me between Tom and the Dementors. For a moment I was confused. I didn't expect the Dementors to be so close.

One of then started to suck my soul but it wasn't too late, I tightened my grip on my wand and yelled "Expecto Patronum !!" I thought about all my happy memories, every kiss mom pressed on my cheeks, every time dad wiped my tears. For a moment I was lost in memories, I could still see the dragon that came out of my wand and the Dementors that ran away but I just couldn't pull myself back to reality or maybe I didn't wanted to, I wanted to enjoy those memories. I felt a hand on my shoulders. Then he pulled me in a hug, that brought me back to that brought me back to reality. It was Dumbledore...thank god he came. I and Tom were taken back inside the castle.

"Ten points to Slytherin" Dumbledore said while I and Tom followed him to the hospital wing. Tom looked at me and smiled as if impressed or maybe trying to say thanks. I was feeling light headed. I walked in the hospital wing leaving Tom and Dumbledore behind.

"Oh dear" The nurse said "Have this potion you will feel better."

I drank it and she helped me lay on the bed. A tear rolled down my cheek and millions of thoughts came to my mind.

What if I fail?

What if I do something wrongand Tom kills me? I will never see my parents ever again. The thoughts faded asI slowly fell asleep. I was too tired, tired of sleepless nights withnightmares. Can a 17 years old really save the world?
