Jack was scouring the Marauder's Map, her most treasured possession. The gray streaked sky outside her window told her that she had been up for an hour struggling to go back to sleep before finally cutting her losses and entertaining herself by staring at the little black dots on the most epic tool of pranking that any troublemaker could ask for. So she had the passages memorized? Did not mean the little dots did not come in use.
She had only been reading the map for a few moments before she realized there was no movement on it. It seemed that the castle slept at three in the morning... But suddenly, movement caught her eye and she immediately bent lower over the map, her eyes narrowing on the name. A smirk burst onto her face as she read it. Keith Nicholas.
Without thinking, she turned and her feet came down on the shoes that were always ready. She pulled them on and her hand groped under her bed before fastening around the bag that she occasionally stored her books in, but was always full of her pranking devices. She was in her pajamas so she grabbed her jacket, which had been conveniently stored on the ground, and pulled it on, zipping it up. She pulled her bag on, held the map and her lit wand aloft and quickly exited her dorm as quietly as possible.
She made her way down to the dungeons, her breath beginning to gather in mists in front of her as she went. It was always colder in the dungeons, but the fact that she was only in pajamas and a light jacket, and the early hours made it colder, and soon her cheeks were pink and her lips were tinged with blue, though she continued on, carefully watching the map.
He was sitting on the ground, looking thoroughly exhausted, something that made Jack have a feeling she had chosen correctly to come and investigate. She smirked as she approached him and stood across from him, crossing her arms to keep herself warm. She smirked and raised an eyebrow, saying in a low voice. "My pranking senses were tingling... So..." She smirked wider. "What'd you do?"
