Anal Swabs. I almost forgot that for a second. Correct me if I'm wrong but was it in Evalution Day when Nicky smiles big time with pride when Grissom makes a comment of Greggo doing a great job on analyzing something for a case??? I didnt think of it now but even if the boys were together at that point, there could have been some serious attraction going on. Nicky was probably thinking, "yeah that's my Greggo."
