 CONT: When Catwoman is seen from the front lying on the glass after  Laurel has hit it twice with the metal bar, there is a strike mark  visible just to her right at shoulder level. In the next shot, now  from behind and through the glass, the strike mark has shifted to  the middle of her back. Had it been in this position in the prior  shot, it would have been obscured by her body and would not have  been visible.
