Nobody would have known about Nick and Greg..
Except the delayed squeezing of Greg's shoulders or the patting of his chest were a little obvious.
They way Nick could go into a lab during a hard case, looking tired and radiating sadness but then come out with a bounce in his step and a smile that was almost as bright as Greg's, was a bit of a give away too.
They wouldn't have been obvious if Nick didn't grow his hair out and have it messed up precariously in the style of one Greg Sanders for several weeks before finding the bangs in his eyes was a bit too much.
They weren't obvious when Greg flirted more with Nick then the rest of the team combined.
Or when Greg would look like a Cheshire cat when he bounced out of the locker room, followed three minutes later by a slightly flushed but content looking Nick.
They most certainly weren't obvious when each would manage to slip the other's name into the conversation at least once every five minutes.
Maybe they were being a teeny little bit obvious, however, when Catherine caught them mid make-out in the break room.
Author's Notes: Ok so this is my first CSI fic. I got into the pairing after noticing a BrokeBack Mountain writer was a fan. Now I'm hooked. Probably more of these to come. Hope you like this one
