Author's note : I know I said I would have Harry's pov in this chapter but there are a few things that happen before I can put Harry's pov in. No, it won't take a month for me to update because I genuinely enjoy writing this crossover fanfic. Also as I have said before this is my first story on so some chapters might not be as satisfactory as others. I genuinely have no idea of how long every chapter will be though I have most of the story planned out. Enough rambling though let's get on with this story.

After the feast was over the Gryffindor prefect Percy Weasly led them to the Gryffindor common room. They encountered Peeves the poltergeist on the way to it who caused them a bit of trouble. They stood in front of a portrait of a woman. Then suddenly it started talking.

"Password?" She asked

"Caput draconis" replied Percy and the portrait swung open. All of the Gryffindors went through.

Percy directed the girls through one door to their dormitory and the boys through another.

{SCENE BREAK}

In the morning Elsa went down to the great hall to get breakfast. Harry and Ron came there shortly after. She was surprised to see people turning their heads to look at Harry. Harry looked a bit uncomfortable because of the attention.

"Why are people looking at you like that?" asked Elsa

"Probably because of all this boy-who-lived stuff. I hate it though." replied Harry

"What? You don't like it?" asked Ron

"Why would I?" asked Harry "Do you want people looking at you like idiots?"

"..."

"..."

"..."

"..."

"Fair enough" said Ron

{SCENE BREAK}

Elsa and Harry went into the transfiguration classroom as that was the class they had first. There was a tabby cat on the desk. After a minute Ron came in.

"Phew! Made it." said Ron "Good thing Professor Mcgnagall isn't here."

"She is on the desk" said Harry dryly

"What are you talking about? That's just a stupid cat" sid Ron

"She's an animagus." said harry

The tabby cat jumped off the desk and became Professor Mcgonagall.

"What?! How did you become a cat?!" asked Ron

"I am an animagus Mr Weasly, and that is 5 points from Gryffindor for coming late." said Professor Mcgonagall "For those who don't know an animagus is a person that can become a specific animal. Mr Potter, if you don't mind, would you tell me how you knew I was the cat?"

"Well, Professor, firstly we are in the transfiguration class and the second thing that gave it away was that you were sitting very stiffly"

"Excellent deduction Mr Potter 10 points to Gryffindor '' said Professor Mcgonagall "Now, Transfiguration is some of the most complex magic in hogwarts. That is why we will be starting from the basics, today you will by turning a match into a needle."

Then she gave them a few notes, showed them how to transfigure a match into a needle then had them try it themselves. By the end of the lesson the only ones that made a difference were Elsa and hermione. Hermione did not seem too happy that she wasn't the only one that changed her match stick into a needle. Then they went to their double potions class. When everyone came he called out their names. He paused at Harry's one.

"Ah yes," he said softly, "Harry Potter. Our new - celebrity"

Draco, Crabbe and Goyle sniggered at this.

He finished calling their names then he started saying

"There will be no foolish wand waving in this class. Here I am going to teach you how to brew potions." he said "Potter, what would I get if I added powdered root of asphodel to an infusion of wormwood?"

"Er…, the draught of living death?" said Harry

"Hmm... lucky guess Potter" said Professor Snape "Where would you find a bezoar?"

"Well sir, I would find it in the stomach of a goat." said Harry

"Final question, Potter. What is the difference between monkshood and Wolfsbane?"

"There is no difference sir, they are the same plant, which also goes by the name Aconite."

"Beginners luck I suppose." said Professor Snape "Now I want all of you to make a cure for boils. On the board" he waved his wand to make instructions appear "are the instructions. Get into pairs and start making the potion"

Harry paired with Elsa and they made the potion nearly perfect. Of course Professor Snape had to criticize that too.

"Potter, Evergreen, you absolute dunderheads, this potion is 2 shades lighter than it should be. A point from Gryffindor for your stupidity."

Just then the cauldron Neville and Seamus were using exploded. Seamus was able to avoid the liquid that came off but Neville got drenched in it.

"Idiot boy!" snarled Professor Snape clearing the potion with a wave of his wand, "I suppose you added the porcupine quills before taking the cauldron off fire? You," he said to Seamus "take him to the hospital wing."

Once Seamus took him out Professor Snape rounded on Harry

"You - Potter - why didn't you tell him not to add the quills? That's another point from Gryffindor."

Elsa got very angry at this and froze the cauldron Draco and this other slytherin called Pansy Parkerson were working on when Harry was glaring at Professor Snape when his back was turned.

After checking a few other potions Professor Snape looked at Draco and Pansy's cauldron.

"How did you two freeze this cauldron? Clean this up now there isn't enough time to fix it." Professor Snape said.

Author's note: I thought it would be good for Elsa to use her powers in the potions classroom since Snape always favours his slytherins which would annoy her. By the way I know the majority of people say Elsa is a Ravenclaw but seriously, Gryffindor has no classes with Ravenclaw whenever Harry was at Hogwarts so what do y'all want? I can't change the classes for Gryffindor to be in the same classes as Ravenclaw most of the time.
