Okay that scene, catch the ghost then wait in there, for like i don't know exactly but you'll hear her if you did it right and she make a few sets of noises and poof she'll appear automatically, just wait and wait, it will happen.
I have a few questions: do I need to stand alone or with one of the recruits; do I need to turn off the lights; how long do I need to stand there? I stood with the lights on and with Tess for 50 minutes.
