I haven't played in years, but here is what Nickie's walkthrough states:
November 12, Monday morning:
Look at the mirror, need to tell the hotel porter. Go outside the hotel, and then back in to tell the porter about Ryker. Go to the hospital and talk to Dr. Young in the booth.
Go to cell five, and Dave will automatically be returned to the hallway. Go to cell one. Playback the audio recording Dave made the previous day, which will be listed in the PDA according to when it occurred, not when it was recorded by Dave ( here it would be 11/10, night, part one). Highlight the pertinent audio tape, and click on play, get the PDA off the screen by clicking on the round button, and click on the patient (same procedure throughout game).
Hope it helps till someone with better comes along.
