Fic: Colby/OC

[cat-13145.livejournal.com]

I read a fic ages ago and very stupidly did not bookmark or save it.
It was Colby slashed with a Male OC (obivious I know, but give me so time). And David finds out, but is cool with it.
Not much to go on, I'm aware, but the only other thing I can remember that might help is a quote from the summary "Why he doesn't date much."
It also had a link to the episode where Colby turns up on a crime scene exhausted after a date.
Really sorry, but would appricate any help people can give.

Edit Found it!!! What didn't help was I was mixing up two fics in my head.
One was The weight of secerts of a Secret Agent by bergann, and the other was Don't have to tell.
Both can be found over at <lj user="lgbtfest">, just clink on the fandom Numb3rs tag.
