Place it at the end of a reveal, after the evidence has already been shown, so the call-out closes the scene. Follow it with an Emotional Damage hit for the friend who was caught, then a baby laughing clip to end the edit on the joke.

This is Babi's voice, just under nine seconds long, repeating that we always know, calling her friend to look at her, and breaking into laughter at the end. It feels knowing and teasing, like catching someone in a secret everyone already saw, and it lands best as a playful call-out between friends who share the joke.
