Place it immediately after the moment of betrayal is shown, letting the accusation close that scene before the edit moves on. Open with It Was At This Moment He Knew to set up the reveal, then cut to the group's reaction for the payoff.
About this sound
This short Spanish voice clip delivers the line asking where someone's honor is, calling them scum in a sharp, theatrical delivery. It feels confrontational and mocking, like a dramatic challenge thrown at someone who has betrayed a code or backed down. The exaggerated tone makes the accusation land as comedy as much as criticism.
