A/N: I do not own Harry Potter, nor do I own "Things I am not allowed to do at Hogwarts"
Remus Lupin, Defence Against the Dark Arts teacher at Hogwarts School of Witchcraft and Wizardry, was teaching the Third Years about Red Caps, when there was a loud knock on his classroom door.
"Come in." He called. The class turned their heads, curious to see who it was.
A large black dog entered the room, a neatly wrapped parcel in its mouth. Remus froze. He had seen that dog before. He had loved that dog like a brother. He had been eternally grateful for that dog. The class gasped. Ron Wesley yelled "It's the GRIM!" The class erupted into chaos, apart from Harry, who, like Remus, was frozen, staring at the dog, and Hermione who had taken out a book, rolling her eyes as she did so. Remus flicked his wand and several loud bangs echoed through the room. The class stopped, panicked gazes turning towards their Professor.
"Sit down." Remus said, his eyes locked on the dogs. "Open your books and turn to page 493."
The class obliged. Remus read the message clearly displayed in the deep brown eyes into which he looked. It wasn't me. Peter is alive. It was him. It was always him. I'm sorry for doubting you. Please. Trust me. Remus nodded, a barely detectable movement but it was there, relief bubbling up inside him. The dog bounded towards him, his eyes shining. He dropped the parcel at Remus's feet, licked his hand, and trotted out. Remus made sure the class was reading, bent down, picked up the parcel, sat down at his desk and opened it. Inside was a note, and a second parcel. Remus opened the note Remembered you saying you wanted one. Padfoot. Puzzled, Remus slipped the note into his pocket, and opened the second parcel.
He groaned inwardly. Sirius had never listened. He had told him countless times, even made him write it out. Remus Lupin does not want a flea collar. But there, laying before him the centre of the brown paper, was just that. A beige flea collar.
