When Brant is lying at the bottom of the stairs as the fire begins in Singleton house, the servant runs to him. In a brief shot, we see Brant raising his arm as if he is coming to and beginning to get up, but in the next shot, as the servant reaches him, he is still lying flat as if still knocked out.
During Brant and Sonia's conversation at her birthday party, they are seen facing perpendicularly to each other. But when the shot changes, suddenly they're facing each other.
