The Who wants to know who you are. I wanted to know what "Right between the numbers" meant. From the depths of the couch, the husband tells me, "It's a football term. As pithy sayings before the credits go, it beats 'Looks like the shotgun formation!'" He's right. It does.
When we get back from commercials, Nicky's come to pour kerosene on the smoldering fire of Catherine's resentment: "I don't get it. Grissom calls me up, I come out here, and I find you. Things were a hell of a lot simpler when we were all on the same shift." And across the viewing land, people begin printing homemade T-shirts bearing the legend "Nick Stokes: He Speaks For Me." Catherine asks in a I'm-joking-but-not-really kind of way, "You saying you don't like me as your boss?" Nick gives her a look like, Why are you asking questions you don't want to know the answer to? and replies dismissively, "Whatever." Catherine looks up with an expression like she can't believe NICKY just said something less than amiable. So she moves back to work-safe topics: "I got a shot cup. That doesn't make any sense because our vic was definitely shot at point blank." Now that they're on safer conversational ground, Nicky relaxes and says, "Yeah, a shot cup coming out of a shell is like throwing a potato chip. It doesn't really go that far."
The two of them quit jaw-jacking and resume gathering evidence. Nicky pulls what looks to be a shotgun pellet out of a tree. Catherine photographs a scuff mark. Nicky collects a second casing -- "That's got to account for at least two more shots." Catherine explains, "Typical mag action -- four in the pump, one in the pipe. This was a chase." Oh, like a biathlon? No, wait, that would be if someone was skiing and shooting at someone, wouldn't it? We see the chase in flashback -- sadly, there are no skiers, which would have raised the comedy quotient considerably -- and it's just what you would expect. Someone's running while bullets fly by, and we see that the scuff mark Catherine photographed was actually a bullet glancing off a low-lying rock.
