Greg is (weirdly, unexpectedly) lusting after Sara, his affection for whom causes him to regress to adolescence as he keeps trying to plan a lunch break together. Of course, it’s only when he produces some killer evidence (obtained through the mystical medium of an Internet Search Engine) that he actually gets her attention.

Seems like Catherine was right.
Greg: Hey, Catherine: do you think Sara would ever go out with me?
Catherine: Sure! As long as you don’t tell her it’s a date.
Greg and Catherine will forever be my ultimate CSI ‘ship; but, as ever, Warrick and his rippling pecs are getting in the way.
