Comment on Mias and Elle Chapter3 pg50 by StressedJenny

Hmm... I'm really curious about this door he wants Elle to likely open with her powers (at least that is my assumption based on what I read earlier). For example, why can't he open it? Who made it so he can't open it? Should he be opening it? What's inside that he's so fixated on?
Curiouser and curiouser.
