So, update on this. I had thought I found a potential workaround:

-On the back of the center mirror, Wendy finds some paper taped on that says "DO NOT REMOVE"

-Wendy, being the rebellious teen she is, decides that a piece of 8.5 x 11 can't tell her what to do

-Upon removing it, there's some kind of symbol carved into the wooden frame (which acts as the seal (but nothing too obvious, so as not to make her too suspicious))

-She's curious as to why someone would bother covering it up, running her fingers along it as she does so

-In the process, she feels a slight prick in one of her fingers, and looks to see a small splinter and just a tiny bit of blood

-She goes to get a small bandage and some tweezers out of the first aid kit, all while grumbling that whoever made the frame apparently never heard of sanding

-Unaware to her, that tiny bit of blood left on the seal was all that was needed to release what ends up coming out of the reflections when she returns

However, this writer I chat with said the following:

"It's a little contrived since Wendy isn't that stupid, but it does get you where you need to be. Still I think something more subtle would work better, since she doesn't really have a reason to mess with some mirror."

I can see where they're coming from with that. What do you think would be a good middle ground for this?
