----------------------------------------------------------------------------------------------------------------------------------------

The days at Hogwarts passed. The Defense classes Against the Dark Arts were undoubtedly the worst. Elsa knew that in other circumstances would be putting Elena fire on the teacher at a glance, since lately the brunette walked a little changed.

It was Monday and again the Slytherins and Gryffindors followed to class DADA. Elsa was trying to get Elena to stay a little less angry when the teacher entered the room.

- Good morning, class. - He spoke with his usual indifference. - Without further ado, then begin the lesson.

- What spell will teach you today? - Jennete raised his hand.

- Glad you asked, Miss Slytherin. - Jafar almost smiled. - You are already well advanced in Charms Fire regard, having already learned spells like Incendio, Fiendfyre and Lacarnum Inflamare. So today I will explain on a more advanced spell. The most powerful existing fire spell.

- Which One? - Jacky who was asked. Sometimes it seemed that she spoke more in class than with friends.

- The Spell Infernus. - Jafar said.

Elena swallowed hard and his hands began to tremble under the table. Elsa looked terrified for her.

- Can anyone tell me what spell is that? - Jafar asked.

Elena remained paralyzed in its place and how none of the other students knew, Elsa raised his hand.

- It is the most powerful fire spell of all time. - Explained. - The flames of it can not be erased by someone else other than that launched and can even take any form that the launcher want. A fire is able to burn any material, even those who can not normal fire.

- Excellent explanation. - The teacher gave a wicked smile. - Twenty points for Gryffindor. Now I need someone to test the spell. Miss Gryffindor?

Anna and Elsa raised their heads and looked at him, but Elena remained head down, hoping he would not call her.

- Elena. - He specified.

The brunette held his breath as he said his name and not look at him.

- I can do, sir. - Elsa offered, trying to take the sister of the situation.

- No thanks. - The teacher denied. - Your sister has been the most effective student with fire spells. I'm sure she has full capacity to do this too.

Elsa looked at Elena and spoke softly in his ear.

- You do not need to do this. - Murmured.

Elena swallowed again and got up from his chair, going to where the teacher awaited him.

- All right, Miss. - Jafar smiled and with a flick of his wand, a huge stone appeared in the middle of the room. - Make the spell.

Elena took a deep breath and pointed his wand at the rock. With trembling hand, she cast the spell:

- Infernus!

Once the flame wand outputs reached the rock, it began to disintegrate and in less than a minute, only ashes remained on the floor.

Elena felt the burn and head, saying nothing, ran out of the room. No matter what the teacher would say, Elsa followed.

Running aimlessly around the castle, Elena ended up going to the Astronomy Tower, where they rarely had someone. Once there, leaned against the wall and slid down to find yourself sitting on the floor. Curled up with his head in his hands, trying to endure without screaming headache he was feeling and now spread throughout the body.

- Elena! - Elsa called, coming near her.

Elsa touched the arm of the other, but quickly turned away.

- You're on fire. - The blonde was startled.

- Elsa, get out of here. - Elena asked without looking at her sister.

- But ... - Elsa tried to argue, but was interrupted.

- GO! - Elena screamed and it was then that the blonde noticed some flames beginning to come out of his hands.

The blonde nodded and left the Astronomy Tower. Once realized that Elsa was gone, Elena stopped hold and let the flames erupted from within and spread the place.

-

In the room, all students were still stunned by the sudden departure of Gryffindor twins. Anna wanted to go out and look for them, but the teacher did not allow.

Jafar ordered all students to read their books in the chapter that talked about Fire spells. Luckily for him, there was a chapter on the spell Infernus.

That was it good because there was one thing that Jafar had not spoken and that Elsa had also not explained, since he did not know. The Spell Infernus should not be used by anyone. It is the most powerful fire spell there, but there was no one in all of existence that could use it.

Professor of Defense Against the Dark Arts smiled and continued to watch the students. He adjusted the purplish black cape and he was satisfied that his plan was working.

-

It was night when Elena left the Astronomy Tower. Feeling as normal as possible, she went to the Gryffindor common room.

Anna and Elsa were sitting in armchairs that were in front of the fireplace, while Alice and Merida were sitting at the table that was there. The four friends looked when the hole portrait of the Fat Lady opened and Elena entered the Hall.

Elsa ran to the brunette and hugged him, noting how much older now seemed warm. A doctor would say that her temperature was so high that it should already be dead.

- All right? - Elsa murmured.

- As far as possible, yes. - Elena sighed.

Was not long before Anna ran up to the sisters and overthrow the two in an embrace. Merida and Alice also approached by helping Gryffindor sisters to raise.

- Where were you? - Alice asked worriedly.

Elena shook his head in denial and without a word, went to the stairs leading to the dormitories.

Merida, Alice and Anna immediately turned to Elsa, since they knew that the blonde and the brunette were very close.

- She's not well. - That's all Elsa said before following the older twin to the bedroom.
