Place it at the end of a short exchange, after the obvious claim has been made, so it closes the scene. Put It Was At This Moment He Knew before it to frame the realisation, then follow with Bruh Meme for a second reaction from another character.
Sobre este som
This is a very short Russian voice clip of a single speaker saying 'konechno', meaning 'of course', in just over a second. The delivery is flat and matter-of-fact, making it feel dryly confident rather than excited. It works as a deadpan yes, a knowing agreement, or a sarcastic reply to something obvious, landing best when the answer was never really in doubt.
