Question: Things I noticed looking at the CSI picture: Nick has a cut on his neck, the dead body has a police badge in its pocket, and the bench says "GG + ?". Am I on to anything?

Answer: Not sure what the cut on Nick's neck means, but the badge is definitely a big clue and, based on the hints Jorja Fox dropped in last week's AA, I'm betting the "GG + ?" has to do with Gil engaging in some hanky-panky with someone.
