How does Wolfe get shot from an air powered nail gun with no air hose attached?
Near the end it shows the son shooting his mother with the nail gun. When his mother fell to the floor there were heaps of nails on the floor. There should be no nails on the floor as the only ones shot hit the victim. Also, tradesmen would never leave nails lying around.
At the start Eric was driving frantically taking Ryan to the hospital. He reached across to hold up Ryan and took his eyes off the road, at speed, while he was dodging around cars and switching lanes. Totally illegal. He should have stayed on site and waited until Ambos arrived.
It was revealed that Charlene was the one who shot Ryan with the nail gun. But Charlene was talking to Calleigh at MPD when Calleigh called Ryan to go to the house. So how could she have gotten to the house before Ryan?
