I wonder about one line in Drama Detective Rhonda Boney: Has Amy got friends we can talk to? Nick Dunne: Um...no, not really. Detective Rhonda Boney: No friends? This whole town? Nick Dunne: She was very close with my mom, before she passed away. And you know, we have a pretty serious homeless problem in our neighborhood. I think maybe you guys should check that out. Officer James Gilpin: We'll look into that. Detective Rhonda Boney: So you got to the bar around 11:00 today. Where were you before that? Just to cross that out. Nick Dunne: Well, I was home. I left at 9:30, I got a cup of coffee, a newspaper. I went to Sawyer Beach and read the news. Detective Rhonda Boney: Did you visit with anyone there? Nick Dunne: Well, I mean I kind of go to Sawyer Beach for the solitude. --- "Where were you before that? Just to cross that out." - In this line, what does "just to cross that out" mean? and Besides what is "that" in between 'cross' and 'out'? Please help me! Thanks!!
