When breaking into the government building, there is a close-up of Sarah's shoes, high-heeled boots. About a minute later, she is seen running through the hallway with flat-soled boots on. It switches back to high-heel later in the scene.
At 6:30, after Sarah has been cutting up the chicken and Chuck leaves the room, while she starts looking for the glasses in the apartment, she spots a photo of her and Chuck. The picture she reaches for is different from the close-up picture that she ultimately views.
