Place this clip right at the reveal beat in your edit, after the traitor's action is clear. Follow it with No God Please No for the victim's reaction, or lead in with a tense sting so the accusation lands as the payoff.

This is Xigbar saying 'Shouldn't have betrayed us' in just over two seconds, a clean spoken clip with no music behind it. His smooth, drawling delivery feels smug and coldly judgmental, turning an accusation into a knowing taunt. It comes from Kingdom Hearts II, where Xigbar is a member of Organization XIII.
