Place this clip immediately after the age reveal in your edit, then follow it with Emotional Damage to close the scene, or cut to Bruh for a short disbelieving reaction from the group.

This is a roughly five-second Spanish voice clip built around the line “Ella me dijo que tenía 18,” a plain spoken admission that puts the whole joke on that one sentence. It feels awkward and sheepish, with a sinking, caught-out humour that suits a moment of sudden regret. The short length keeps the focus on that one uncomfortable reveal.
