What car was used to drive Barbara and Denise to the VDs before the bar? Where was this car parked when they left? Was it blocking DVDs van? When the group came home afterwards, where was BVDs car parked, as well as the other car? DW said he did not notice Damon's car when he drove by to go home. Was there another car in the driveway, that DW would not have recognized? Thus indicating occupation of the house... Or were there no cars in the driveway? What type of car did the men drive in? Who drove?
