As he left the dining hall and walked through the corridors he ran into Filch who was cleaning the windows, William made a move with his wand and helped him with the cleaning, Filch said nothing as he could do it himself in the future, he was just waiting for the day when William would fulfill the deal.
As he was the first to wake up, he was also the first to finish his meal and as he walked through the corridors, all was quiet, there were not many students.
Then, as he turned a corner, he saw a young girl trembling and barely holding on to the wall.
Oh no,' William muttered to himself, but before he could even turn to leave the young woman collapsed, 'no no no no no no'.
It was easy to recognize the person, red haired first year and a bit weak, Ginny Weasley was easily identifiable. She could leave her there, someone else could help her, it wasn't necessarily her responsibility, even this could have happened behind the scenes in the official story.
POV Ginny Weasley
I did it, I did what the newspaper asked me to do, I didn't want to, but I couldn't refuse, besides he doesn't seem to want to hurt me, he's my friend and he listens to everything I say, even my complaints about classes.
Now I feel weak, my body has no energy for anything, I want to get up, but all my efforts are useless.
Someone will find me here on the floor, they will talk about me, Percy will know too and Mom will worry, I don't want them to find out.
I don't want Harry to think of me as weak and pathetic.
Then I heard the sound of shoes, I could barely see, but I'm sure these aren't the shoes that students can wear, I know because Ron tried to get Mom to buy him different shoes for his classes, although Mom refused.
Could it be a teacher?
What teacher could have found me?
I only know Professor Snape, Professor Lockhart, Professor Kettleburn and Professor Flitwick... my head hurts too much to think about which professor might have saved me.
Then I felt a pair of arms go under my body and lift me up, I must look very pathetic right now, I don't want to see the Professor's face.
"I will take you to Madame Pomfrey, she will help you and you will be able to attend classes in a few hours."
That voice... That voice, I had heard it before... it was during my trip to Hogwarts when I was with Hermione.
William... No, that's not possible. My brothers told me many times that William was not a good person and that he really enjoyed playing with people's psychology to appear to be a hero, they said that he took advantage of last year's incident to get credits and go to Brazil.
But when we were on the Hogwarts Express he didn't seem bad, he even talked to Hermione like they were equals, he's not like Draco Malfoy or the Slytherin students.
I could barely open my eyes to look at him, but there was the face of William Rosier, the young hero who captured Fenrir Greyback during his holidays, it was impossible to mistake him with that white hair.
I'm sure William is not a bad person, my brothers are wrong about him. Although I wanted to keep looking at his face, my body seemed to lose more and more strength every second, and then I finally closed my eyes.
...
When I opened my eyes I was in the infirmary, just as William said when he found me, I touched my pockets and found the diary, everything was in its place.
"You're awake now, really it was just a lack of energy. Girl, you have to eat and rest properly, not everything can be studying, you also have to take care of your health."
I nodded my head, I didn't want to cause the nurse any more problems, surely she had more problems to take care of besides me, but before I got out of bed I decided to ask.
"W-where is he?"
"Where is who, William?"
I nodded my head.
"He left shortly after hearing that your situation was not serious, it was really shocking to see him hugging someone, the boy always gives everyone the impression that he doesn't care about the students in his house, but in the end he helps them all when they are in trouble, he's just a kid."
I was right, it was William, no doubt about it, my brothers are the ones who have the wrong idea about William, I have to thank him for the help.
Pov Narrator.
William had arrived late for class, surprising many as he was always the first, when he got to his seat Parvati stared at him.
"What happened to you?"
"Script problems, nothing important."
William's answer left Parvati with more doubts than answers, it wasn't normal for him to be late, but just looking at his face it was obvious that he didn't want to explain everything.
Ron, who was sitting next to Harry in the furthest seats, stared at William who was late for class, "Even Rosier can be late, it's funny to see him tired from all that running, the moving stairs must have played some kind of trick on him."
"It's not funny Ron!" exclaimed Hermione, annoyed, "If William was late for class, something really important must have happened."
"Sure, whatever happened to make him late must not be good, urgent matters in dark families are not good at all."
"How many times do I have to tell you to believe me? William is not a bad person, he is different from the rest of his family, he helped Harry last year and he helped you too".
He said that Ron couldn't deny it, he saved his life by giving him the potion in the Chamber of Secrets trials, and Harry had also told him what happened when he fought Quirrell to save the Philosopher's Stone.
"I also believe the same as Hermione, William is not like Draco Malfoy, I think we should give him the opportunity to relate to everyone, even Neville talks to William," Harry said to calm Ron's misunderstandings.
