She quickly shuffled through the pile of papers to find the one she needed. "But if I put the charm a few steps before the gate, then it'll [i]definitely[/i] get activated before she's ready. [i]And[/i] if she did any of her homework on protection charms and checks the threshold itself, [i]that[/i] will be completely clean. I just need to make a false threshold for the charm to take to..."

Lillith had a grand time finishing Lock's punishment with a reward for maintaining good behavior for the duration. With excellent timing, the replacement for her damaged anniversary gift had arrived that evening.
