Place it right after the denial in your edit, then follow it with Risadinha de Ladrão to close the exchange. If the moment needs a colder reaction instead, put Awkward Crickets after it and let that reaction close the scene.
O tym dźwięku
This is a very short spoken Portuguese clip, lasting just over a second, in which a voice says the phrase 'Meu irmão na moral'. It feels incredulous and playful at once, like catching a brother in the act and calling him out with mock seriousness. The delivery lands as a quick, knowing reaction rather than a long explanation.
