When Abby and Luke are in his sister's restaurant, after Abby poses as lawyer to regain his clients, they walk and chat through the restaurant on their way out, while Abby is holding a fresh and untouched-yet coffee mug in her right hand, and her bicycle helmet on her left hand.
A moment later, as the scene (the camera) shifts to the outside of the restaurant, they both seen walking and continue the chat throughout of the restaurant door, while Abby is holding her bicycle helmet in her right hand, and her left hand is completely empty.
Abby's hometown is Poplar, Oregon, but when she and Luke are in court, the flag behind the judge is the flag of the state of Washington.
