Jack had just nipped into the kitchens for a bit. For once, her stomach clock had not gone off for dinner and she had been on the Quidditch pitch. So she had played through most of dinner and by the time she had stepped in, all the good food had been mostly picked over, leaving her a few minutes to cram down a few rolls.
But now, away from all the hubbub, she was loaded down with bacon, a few sandwiches, some pudding, some sort of tart, and pumpkin juice; all to satisfy her hunger. It was not quite curfew yet and Jack had very little aspiration to wait until she reached Gryffindor tower. And she did not mind the coolness of the lower levels of Hogwarts...
She sat against a wall and stretched out, unfolding the tablecloth the house elves had wrapped her food up in. She took a swig of her juice and then set out all the food, grinning to herself. Just like a picnic... She bit into a sandwich. Roast beef. Not too shabby.
Boredom leaked into her bones; it was a reoccurring demon of hers and was nearly insatiable, just like her appetite. Still, she usually had some idea of how to cure it, and she began by thrusting her hand into her bag and withdrew the first thing her hand seized. One of the reuseable hangmen from her shop, Weasleys' Wizard's Wheezes, which she co-owned with her cousin. She grinned and began to set it up with one hand, eating her sandwiches with the other.
