Aiden probably never would have noticed the box had he not decided to preemptively buy some extra paper for the printer. He missed it until his foot sent it skittering a few feet down the hall. Understandably slightly wary about a package sent with his name written in block letters on it, he carried it inside and opened the packing tape with scissors.
He littered the floor with newspaper as he dug until his fingers hit something hard and cool. Hesitantly, he lifted it out - and stared as the shiny black handle of a knife came into the dim light. The note taped to it revealed all, of course, and he couldn't quite help himself from feeling faintly surprised and even (shock and awe!) a little grateful. It was four inches of steel death, and it came out mostly at his command.
Looking at it almost made him uncomfortable. He hadn't actually expected her to make it.
In any case. This meant he probably owed her a drink, or something like it. Because God forbid Aiden Shepard ever actually thank someone properly.
