I prefer the blackmail theory. I'm pretty sure the envelope she got right before the ninth twilight in which she went out to the entrance hall was somehow sent by the child from 19 years ago.

The thing about Natsuhi's door is interesting because her door is almost always covered in those scratch marks, across a few chapters, regardless if she's dead or alive or in that room.

I think she may have had the envelopes and were told to find them at specific times, or Maria may have placed them "Uu! I'm her messenger!"

The envelope we had a discussion on page 1437-1438 about some of our ideas about it.
Some of us figured it was the child from nineteen years ago, others believe there may not have been an envelope in the first place. My guess is on the former.

Don't apologize, discussing our thoughts and theories is what this thread is for =)
