Well I am devising a plan in chapter 3 - so let's see.
Have you looked at the thing and tried a button? Also have you been back to your friends office? You'll need something that is in the once locked room. There will be a note underneath it. Check near the door area - where the "thing" is. I love all this cryptic talk
You should have an idea of what you need after you try the button. After your friends office search you should have something to "capture" what you need to get an old item out of the "thing"
Also be sure and use your crucifix and put it in line with obejects to be cleaned back at the lab.
