Percy had decided to nip round the office. It was far easier to snoop over the files when most employees weren't about, and he wanted to gather a master list, to pass on to George and Fred. He'd taken a few sheets of parchment, and worked for the better part of three hours, writing out everything he could to store in the charmed quill. He wasn't sure exactly how much could be stored in the quill, but he was going to fill it and then send it by owl when he got out.
He stopped and stood, stretching and with a quick spell, incinerated the parchment he'd written on so there would be no evidence. Everything was neatly put back, and Percy made his way out of the external office of Umbridge, heading towards the main floor and the floos. He'd had the quill in his hand and was readying himself to put into his pocket when he turned a corner and plowed right into someone.
Papers flew; curses flew. And Percy's quill shot out of his hand to land in the mess.
"Bugger," he swore as he squatted down, snatching his quill up before it started writing all over any parchment it touched. He looked up at a woman with short hair and said smoothly, "Hate to get ink all over your papers," he added, stuffing the quill into his pocket.
"Excuse me, please. I had no idea other people were about," he said in a the way of an apology to the woman as he began to move papers about.
