The only chance that I even get someone in that room is to show the Constant the blue print as the designer. Then the Constant would go to the tower and call Sophia and ask her to go upstairs. But after their private conversation, the Constant stood by the table for a while without any interaction option activated, and Sophia just walked away which left me no chance to do it either. I knocked her out and dragged her near it and still no interaction option appeared.
According to what I learnt from “Another Life”, I should lure someone to get in front of it and launch the kill from behind. But whom, and how?
