Near the end, when Elena comes out of her shack and walks to the right, the shadow of a boom mic is seen on the building.
Whenever anyone went to Elena's shack in Dodge's slum-type area across the tracks, many of the other people that lived down there were sitting or standing around, including the first time Sykes and his partner came to Elena and started threatening her. These residents started walking toward Elena's shack to protect her. Sykes thought about it, and he and his partner left. Yet when they came back and threw Packy's jackknife through the window, after supposedly kidnapping him so that Kip would come out to face them, none of these people are around.
