The locker room.

You go to the student area and see that it's populated by just three or four people, none of which you could really name. And so, you ignore them and walk into the locker room, noticing immediately one thing; it's just as empty as the main hall. As you go further into the room, you notice a few students taking their belongings out of their lockers. Your eyes catch the figure of Kelly rather quickly, as she struggling to get her locker open.

You suppose you could drop in and see what's up.

Not to mention, if she's having problems with the lock, you could actually help out.
