She Whispers Something And They Both Turn To Look
Classic whisper-and-point situation. One girl leaned over to her friend, said something, and suddenly they were both locked in staring at the same thing.
About this scene
Outdoor public area, afternoon. Two friends walking together. One whispers something brief into the other's ear. The whisper is short. The synchronized turn is sharp. They both face the same direction at exactly the same moment. Neither of them turns back forward for the next thirty seconds. They continue staring without saying another word.
What to watch for
The synchronization is the practiced friendship. They have done this before. The whisper is the trigger. The turn is the response. The shared stare is the bonding moment. Watch their feet. They both stop walking at the exact same step. Neither one of them needs to remind the other to stay. The thirty seconds of joint watching is unbroken. They do not exchange words during the watch. After the source moves on they finally look at each other, smile, and continue walking. They never discuss what they saw.
