Now before you read this, I am not aware of anyone pointing this out, and I apologize if anyone has stated this before. But I seem to find another piece of eveidence of the intrusion shell, right under our noses. Tess is gone and I have never noticed this unitl it happened, but there are multiple sets of ghosts just sitting on the desk. If you look closely, there is what seems to be an intrusion shell. I know it is already in the game but I thought I would share this little piece of evidence with you guys :) [Dont have a picture, but if you look up tess everis or go find her station in-game, you'll see the shell]
