Just noticed: Greyhound Bus
When Maura tells Kate she'll send her money to fly to Orlando, and the next thing we see is Kate on a bus, with the announcement, "Next stop. Orlando Airport. Thank you for riding Greyhound."
I've watched the movie a few times before, but never noticed that and today during that scene I started pondering and it hit me ... did Kate take the Greyhound cuz it was cheaper and she could pocket some of the money? Also, we know Maura lived in Atlanta, but where did Kate live? Not sure how long a bus ride that would have been.
