About this scene
Public park, weekday morning. She arrives twenty minutes early for the meet-up. She sits on the bench overlooking the lot and watches every car pull in. When the BBC arrives she does not wait for greetings. She is already walking toward his car before he has put it in park. The encounter starts in the front seat and migrates to the back within a minute. The audio has her saying his name once and not much else.
What to watch for
The early arrival is the commitment. Twenty minutes is a lot of buffer for a casual meet-up. Watch the parking lot in the wide shot. Three cars come and go before his arrives. She lets them all pass without flinching. The instant his car arrives her body language changes. The walk to his car is fast and direct. The transition from front to back seat happens because the steering wheel was in the way. Practical decision, not theatrical.
