A whole lot of doubt. I don't want to interrupt your love affair with Goff and all the bugs, but Feldman will probably rip him up pretty good.
He and Dusek cannot escape the fact that Faulkner was numero uno when it came time for Dufus to call an entomologist. Goff got to look at Faulkner's work. Needs no explanation.
Of course he will to an extent but you don't realize that at this point it doesn't matter. All Dusek needed was an expert that would put the date at 2/2 and say this is the minimum time she was there. From this Desek has the testimony he needs.
