You know how Bozer made that Kevlar threaded/reinforced evening gown for Cage? Well, what I want is for Bozer to start feeling scared for Mac (maybe after he got kidnapped) and maybe he also remembers/flashes back to when Mac was bullied in school. In any case, he starts slowly replacing Mac's shirts with Kevlar woven ones. To what extent, if at all, Mac realizes this and where it goes from there is up to you, anon.
