Place it right after the awkward reveal in your edit, then follow it with the Sad Violin for mock sympathy before the Nelson's Ha-Ha! lands the laugh, and keep the Wrong Answer Game Show for a second failed attempt later in the scene.

This roughly six-second Portuguese voice clip centres on the phrase about sticking a finger in a wound and twisting it, delivered with a pointed, teasing tone. It lands as a sharp, slightly awkward jab, the kind that calls out a sore subject everyone was avoiding. The delivery makes the sting feel playful rather than cruel, so it works best as a knowing reaction to an uncomfortable truth.
