Final Puzzle idea

In the cell where Emily stays in the basement section there is a doll with Marie written on it's feet

Now in the Chairman's office there is a pen you can use to write the symbols order, however you can decipher the Moon puzzle by looking at the photo found Lead researcher's office and you can still pick the pen up and put it in your inventory

What if by having the pen while in your inventory you interact with the doll and maybe you get a prompt to write Marie's name on the doll

The room has a giant hole where the Girl uses it to spawn, however she never spawns in this specific one. I think that this puzzle requires you to get her to spawn in the room and interact with the doll

I'm thinking the puzzle is in this order:

-Analyze the hand

-Grab the Pen in the Chairman's office

-Interact with the doll

-?

-Grab the doll somehow

-Carry emilly and the doll to the Lead researcher's office and do the puzzle.
