Numb3rs Fanfic Finders

I seem to have lost this fic and I'd really like to find it.

All I remember is Colby and David taking Charlie to some warehouse (crime scene?) to get some sort of data or something to help his math. They didn't realize that explosives (a bomb?) were left behind from the original bad guys. It blows up and injures all of them. Charlie was hurt but managed to get Colby and David out of the building because it was on fire, I think one of them, maybe Colby was stuck under something and Charlie exhibited great amounts of strength to drag them/move whatever Colby was stuck under to get them out. They all go to the hospital and I remember someone telling Don how much of a hero Charlie was since he saved them all. That's all I remember from it, I'd really like to find this fic again. Any help would be appreciated.
