That was a cool episode. Thanks to Greg it’s confirmed that “The X Files” exists as a TV show in the “CSI” universe. So no crossovers, I presume. Poor Greg though, chomped on by a suspect! But he gets his sample anyway. 
The bedroom scene was a sweet interlude. They’re geeks, of course they lay in bed watching old monster movies and build models on their nights off. What I can’t believe is that they have time in their busy schedules to care for a dog, let alone a big drooling large breed. Besides I always thought Grissom went for briefs, not Boxers. [rimshot]
Unless it’s a seventy-two month gestation, no, she isn’t pregnant. She just has that thin frame and if she slumps at all her tummy sticks out. Jorja herself told a college magazine last year (sorry, no link): “There’s a point in the year when it’s been raining a lot in L.A. and it’s not that easy to work out, and the Heineken six-pack starts to show up around the belly.” So it’s beer, not babies (there’s a rallying cry!
)
sigh myskepticsight, I wish you’d put your last sentence in a spoiler box. Not because I hate LH - I don’t, I just hate what they did to her character in that awful “pirates and Nazis” episode last season - but I would have preferred to be surprised. But since you mentioned it, yeah, I also want her and SS to meet.
About that model in the last scene. I don’t think Grissom is the MK for the same reason I think Hodges isn’t the MK, namely the spare time factor. As to why Grissom is making a miniature, I have two ideas:
It’s a “reverse forensics” thing, á la the Keppler episode, to lure the real killer
or,
Grissom is sublimating his frustration by showing he can duplicate the signature and thus match the killer’s skill, easing his feelings of professional impotence. [/armchair Freud]
Don’t forget that in the earlier bedroom scene he was quite openly carrying around a piece of the model. So Sara knows about the project, whatever its purpose may be.
