Back to the "overprotective mother" discussion, I might get "fannysmacked" for sharing this, but I had a totally different take on that whole conversation between Greg and Grissom--maybe I'm just reading too much into it. I was wondering (please don't fannysmack me, I love Greg just as much as the rest of you), considering the lack of athletic participation, overprotective mother, and seemingly lack of success in the dating field (though I can't understand why) could be indications that maybe Greggy is in the closet? Not that I necessarily want it to happen, just wondering if anyone else had thought it or if it was just me. I'll go run and hide now.
No need to run and hide, but there is absolutely no way and no reason to think that Greg is "in the closet". He's pure hetero, and has been shown to crush on girls and only girls!
Greg has dated before. He once talked to Nick about how he was checking out a date's DNA, not to mention he wanted that hooker's phone number, the one Nick helped in the first season. He's been shown to flirt with girls in the lab, not to mention that he's always had a crush on Sara. Probably still does.
