Just after Steve Arnott has been suspended, Kate and Dot are watching him leave from the mezzanine balcony. Dot's butterfly stitches on his chin have gone. In the next scene, Dot is visiting Kate in her apartment and the butterfly stitches are back on.
Denton is seated on the passenger side of a car and is shot on the right side of her forehead by the driver, blood spattering from the left side of her head onto the passenger window. Clearly the bullet passed through her head and would have shattered the window but it remained intact.
