In the beginning, when Jo gives Bill the divorce papers, he flips through them to make sure they're all signed. He finds a page she missed that has a bright red arrow showing where she should have signed, but when he shows it to her, the arrow is gone. Then when she takes the papers from him to check what she missed, the arrow is back.
I may be wrong on this, but isn't in the beginning there a lot more papers together that at the drive in when she's signing them??? I remember Bill going through 5 or so papers, but Jo only had three and signed the last one.
before he turns it over there are two arrows. When Bill shows Jo there are none visible. 1 his hand covers up and the second one disappears. When Jo goes through them.. there are two visible ones.
