Switch to EM Vision and examine the woman’s head. That will reveal the implant, shown in the picture above, which helps you identify her. That is not all, as you can also press the button indicated by the game in order to hack into Pieta Sagan’s mind and play through one of her nightmares.
You start off in a location resembling apartment 114, but you will soon find yourself in an unknown hospital. The next scene has a hill you must climb up on. Keep pressing the up movement key or hide behind the objects that you pass by, so not to get pushed back by the blows of wind. When you reach the fence, squeeze through the opening on the left.
After reaching the very top you must perform several simple actions. First, press the button shown in the picture, and then grab the hanging cable.
You must carry the cable to the left (during the intervals between the blows) and plug it in the slot shown in the picture 1. Finally, interact with the slide seen in the picture 2 and drag it maximally to the right. That unlocks the upper passage and you can approach Pieta to talk to her. The dialogue options that you choose in this conversation do not matter, as the decision on how you conclude the case is only made after leaving the nightmare and returning to the real world.
Case #628 can be completed in two ways. The first one is to reset the system, which terminates the connection between the minds, resulting in Pieta’s death. The other option is to restore the connection between Pieta’s and Paulina’s minds.
In both cases you must interact with the computer in the room, go to the programs tab and select the program Cephalus_7 .34 (picture above). The left square stands for the option 1 and the right one for the option 2. Regardless of your decision, the case is concluded.
