Numb3rs Fanfic Finders

The first one is for an actual fic. I was reminded of it after watching Calculated Risk (I love woobie!Don in this!). He and Charlie are in the garage, I think, and Charlie comes out with all this stuff about Don's life and basically makes Don break down and cry (although to help him, not hurt him). Can anyone direct me to that one?

The second question, inspired by watching Assassin, is to ask if there are any Charlie/Gabriel fics out there? I thought they had some good chemistry and I could see it as a fling-type thing. Or even something gen, where someone mistakes Charlie for Gabriel, because in the scene where they first meet, and you see them from the back and a distance away, you can't really tell which one is which...

Thanks!
