Put this clip right after the mistake is revealed in your edit, then follow it with emotional damage for a bigger fallout or a short bruh to close the exchange before the next scene starts.

This is a short 3-second voice clip of BeastQT saying 'Pokaisia', the Russian word for repent, delivered as a blunt one-word command. It feels funny and mock-serious at the same time, like a playful scolding that lands as a joke rather than a real lecture, which is why it works as a quick reaction.
