Numb3rs Fanfic Finders

Hi all,

Having a nostalgic Numb3rs moment and I'm looking for fics in which Charlie sees Don's battlescars for whatever reason (glimpses him changing his shirt, sees him with skin exposed for some other reason, etc.) and Charlie is upset because it drives home to him how dangerous Don's job is.

Gen or 'cest is ok, and it's also fine if this is not the main part of the fic. I checked the tags and scrolled through the last few pages; didn't find anything directly matching.

Thanks in advance. :)
