Numb3rs Fanfic Finders

Hey guys I seemed to have lost this fic and can't find it! /0\

I remember is was on FF.net, and an old childhood friend of Don's (who I believe is also an FBI) agent comes to work with him. He's a crooked agent, which means he's involved in their case somehow and he used to bully Charlie as a kid but I think Don just turned a blind eye towards it or didn't see it.

Once he's working with Don he continues to bully Charlie and tells him to stop doing stuff with his brother that sorta thing. I remember it's Colby I think who finds out and he gets really pissed at the guy and wants to beat his ass. Then Colby, Megan and David tell Don about it.

I think the guy gets Charlie hurt somehow with the case but I may be wrong. Oh and it was GEN and when Don finally finds out he's pissed as hell.

So any help to find this fic would be appreciated!

And with that note I will take on any bullied!Charlie fic with protective!Don

Thanks!
