With that, he handed Tom the box of the quill in question and Tom took it carefully, asking himself if he was really going to find an explanation for this one. He sighed inwardly and opened the box to make a show out of this. One of his eagle’s quill was indeed in the box. He didn’t remember Harry taking it from him but it was obviously possible. They often used the other tools, notes or clothes. Himself still had Harry’s comfy jumpers in his wardrobe. He was still sleeping with one, even if he hated the Griffyndor at the time. But this quill was a generic quill, everyone could find the same easily.
