Can the killer impress himself? How was it that Kam did not impress the killer? He knew about how the lights were blown. Did Kam share that?
Where the gun and night vision goggles put in the top drawer after Kam and Ronnie did their search? I can not imagine them not checking the drawers with all the searching they did.
When Kam and Ronnie were investigating the crime scene, there was a zoom on Ronnie's shoes. I thought, hey, that is a clue as to who the killer is, since there were those large shoe prints last time.
And then he gets killed.
So what does the killer get? That person can not win, so are they out?
Also, I would be more impressed if the killer knew who they were. The players are trying to work out where people were, and that does not matter since the killer did not have to actually do what his story says he/she did.
