A troll

3 month have passed since Allan come to Hogwarts, while he don't do exceptionally in potion he still do good, but he is exceptional ini Transfiguration, charm, history of magic, astronomy and others.

He read books in library when he has time, at night too he read books there he can do it because he can blend his presence to be the same with his surrounding.

Crystal and Allan spend most of their time with each other so their relationship got better.

He just just having dinner when Professor quirrel stumbled to the podium while shouting.

" a troll a troll in the basement, i thought you should know that " then he faint.

Allan heart shook as Crystal is going to the bathroom near the basement change is high for that troll going to the bathroom.

" silence, prefect lead students to their dormitory, all teachers come with me " Allan has already gone running to the bathroom.

His step is silence and without sound even when he's running, he run with great familiarity.

He reach it not to long later, but he's not alone as 2 boy named Harry Potter and Ron Weasley also there confronting a troll, Crystal also there trembling but protecting a girl named Hermione.

A stench enter Allan nose, the feature of that troll is hideous, with green skin holding a club in one hand.

Allan can see a bruise on Crsytal ankle, his emotion go out of control in only that split moment and he point at the creature head with his index finger and recite an ordinary spell.

" Aguamenti " a jet of water speeding with extreme speed come out of his finger and pierce the head of that troll the water coming out of it's forehead the water has piercing it's brain, it's slumped and fell sidewardly, undoubtly death.

" Allan " Crystal is the first one to notice him standing behind the troll.

He come running to Crystal who stood there with a limp leg, " only this right ? " he point at her left ankle, she nod.

" yes only this " hearing that Allan let out a sigh of relief then Allan gaze at Harry, Ron and Hermione.

" I leave this matter to you " Allan crouch infront of Crystal she know what it mean so her face turn a little red.

Allan lift her and feel she is light, he nod toward the trio and left the scene before anyone to notice.

They arrive at Slytherin dormitory he enter the password and let Crystal sit, the common room is empty as other students was already in their room, Allan take out his wand and recite a spell as he point to Crystal left ankle.

" Brackium Emendo " her bone mended but it's still has bruise then Allan recite another spell.

" Episkey " the bruise dissapear, Crystal move her left and jump up and down feeling nothing uncomfortable she smile.

" thank you Allan " she hug Allan, he return the hug and he pat her back.

" now go to sleep, if you feel uncomfortable go to madam Pomfrey tomorrow " she nod at his words then she return to her room with slightly red face.

Allan sit in the common room ' a creature like that enter unnoticed is impossible, unless someone let it in ' he thought back about the event.

' the most suspicious one is Professor Quirell while the second one is Professor Snape ' he then thought back about all their behavior and lecture.

' while Professor Snape look evil he is only strict with sharp tongue but he specially hate Harry and Professor Quirell stuttered through his lessons but he is the one who tell the others about the troll, however I still don't have clue ' he sigh, then shook his head.

' what a day ' he thought.
