And since I think we have concluded (or not) that one of the people in Dr. Jekyll's path is Ray, perhaps Nick is the other CSI who's life is in peril?
I was thinking Sara as well but if it says 'his' life well then it's either Nick or Greg. Here would be a good storyline Greg fans have been wanting.. Greg's life in the balance.
But then again, that would negate the spoilers about Catherine also having her life in peril.
I'm wondering too, if indeed Cath's life is in peril, that's why Vartann is in the episode? OR he is actually working the case.
Maybe Catherine is hurt early on in the episode and has to be in the hospital and Vartann is holding vigil there by her bedside. And since Cath is out of commission temporarily, Nick once again has to take over as Supervisor and he and Ray are working the Jekyll case and are possibly in harm's way.
