Possibly this is a figment of my imagination, but I'm pretty sure that there was a Numb3rs episode in which Colby was temporarily taken off the case for doing something that I forgot (shooting someone?). This gave him lots of time to hang around Charlie's office and distract our genius with his clumsily hidden attempts to flirt.

Can one of you tell me which episode that was, please? I tried searching for it, but whenever I start watching an episode, I cannot stop, even though I realize it's not the one I'm looking for. They are all so good.
