About this scene
Suburban side street, parked car, late morning. She's walking a small dog on a long leash and she's been on her phone for the past block. She rounds the parked car about twenty feet from where the action is happening inside it. The flash is mid-finish by the time she's level with the driver door. She catches the cumshot landing across the steering wheel out of the corner of her eye. Her phone arm drops. The dog keeps walking. She catches up two seconds later, faster pace.
What to watch for
Her face goes through three states inside two seconds. Confusion, then registration, then a hard reset. You can see her actively try to put her face back where it was for the phone call. She doesn't quite manage it. The third state is the closest thing to a normal expression and it's still tilted. The dog is what saves the moment. The leash pulls her forward and she has to keep walking, which is the only reason the clip ends when it does.
