Liese was beyond perplexed, her eyes drawn to the book and her brow furrowed in an unreadable expression somewhere lost between irritation and a carefree grin. The pages were yellowed, worn in the middles of the pages where hundreds of hands had caressed, brushed, and even torn through the book that laid open on her lap. Where paper met binding there was a long, thin line no thicker than a hair but all too calling of her attention. Liese glanced right, left, then took a fingernail to the ancient binding and slit it in a single rough stroke. It would repair itself, which was a relief, seeing as she could hardly cast a summoning spell— which was by no means anywhere near the complexity required to send the threads that had held the book together over the years back to their homes.
Tracing the line with her finger, Liese bit the inside of her cheek and let her mind follow her body. The black streak was long and jagged yet somehow delicate in its composure, somehow reminiscent of a fluttering moth light enough to be blown away on the wind. Where nib had hit paper, the line had been thicker; from this, she could surmise that it had begun in the leftmost corner and spiraled out toward the right before darting back to nip the spin. In the middle of the book, it disappeared, then bounced out from behind the bindings for another inch before diving back under again.
There was an almost predatory gleam in Liese's eyes as she tore the book open. Her fingers brushed with a nimble sweep over the threads to pull them loose with the tips. Next, she flipped it on its side on one of the tables. There was something written on the scrawled-on book. A grin lit her features. This was an interesting, though not entirely unexpected, turn of events.
The door, however, had clicked, and it had done so much too loudly for Liese to attribute its unrest to the wind. She slammed the book shut just as a wavy-haired boy, somewhat drawn-out but not possibly any older than herself, found his way into the common room. She should have heard the noise. Now, she was fully aware of how strange she must have seemed, shoving her hand to mark some meaningless place in a bone-crushing, leather-bound book and just sitting there gawking at the newcomer. She'd had a free half-hour; having been excused for 'migraines' just two hours before, she hadn't been required to attend her afternoon classes. She'd been nearly alone in the commons for a good fifteen minutes, watched only by the unnervingly still Rowena Ravenclaw situated over the student study area.
Liese shouted a quick greeting to the newcomer, then went silent. She needed a distraction. She spouted off the first excuse for a lie that popped into her mind: "Hey. You don't happen to own something resembling a frog, do you?" She frowned at the boy. He reminded her of the boy in grade school known well for having once licked a toad. They'd all wondered if he'd get tongue warts. "Because I think some black cat just made itself dinner."
