The exposition on the explosives purchase, disposal of the typewriter, etc. is a screenwriting choice. Is it to give the plot plausibility? Why not use it to show character? Hoplin wants to brag about how smart he is, #JoanMolner gets friendly with #EileenKelly to get info, the way a woman getting assaulted tries to get details about her assaulter. This is just straighforward narrative. #CryTerror #TCMParty #NoirAlley
