Near the end, Darcy goes to Rachel's apartment. She has nothing with her. When we see her storm outside the building, she grabs Marcus' pizza wrapper and walks away. Then the shot switches to her from the back and she has a brown purse, no wrapper. The purse was sitting beside Marcus on the stoop but we don't see her pick it up.
When Rachel and Dex meet on the front stairs of Rachel's house (4th of July), they go for a walk. When the camera is filming Rachel from the front, she keeps her arms behind her back. When the camera is filming from her back, the arms are held in front.
In the last shot with Darcy and Rachel, Darcy's hair in front is down by her face. Darcy walks by Rachel and when she turns around, her hair is partially tucked behind her ear. No indication is made that she does this.
