She will brute- the lock

The key could be anywhere in this cluttered office. Sophia could not afford to search everywhere in here, not with so many windows. Instead, she had a different idea. The padlock seemed quite flimsy and was clearly there more for the idea than to actually prevent someone breaking in and stealing lost stuff. With a bit of leverage, she could break it open quickly and get dressed. Escaping afterwards would be a different issue, but far preferable to having to do so naked.

Sophia looked around for something sturdy to break the lock with. She quickly spotted a thick metal ruler in a pen basket atop the desk. She carefully took it out and slid it through the loop of the padlock. It fit perfectly, as if it were designed for it. Quite happy with this windfall, Sophia prepared herself to put some pressure on the tool and snap open the lock. She got herself into a good position, but first looked back.

By now, it seemed like the group had finally left the reception area, so it was only the clerk left in there. Breaking the lock was probably going to make some noise, but she would try to do it slowly to try and muffle the sound to the best of her abilities. Returning her focus to the task at hand, Sophia began to put pressure on the metal ruler.
