Is it possible to fail the Sigourney missions?
Yes it is, if too much time has passed her pot will get cold and she'll get fed up with you. I had accidentally drived out of Greenvale with Sigourney and the game glitched making it impossible to drop her off. So she sat silent in the car until time ran out and then she yelled at me XD
-If you meet Fiona before going to the hospital with George and Emily she'll ask York why he's talking to himself. Later when you see her for the autopsy she'll be reading a d different book and talk more about her crush on Ushah.
- One of the first department lunches (only if you take it after the Sheriff Office but before the hospital) involves George telling Emily and Thomas that York won't be much help in the investigation because he's from a different organization
-The more often Shadows grab you the quicker your suit gets dirty. I was able to get two suits dirty within a couple hours in game time.
