Place this clip at the end of a suspect claim in your edit, right before the cut. Follow it with awkward moment for the reaction that follows, or lead in with eh eh ehhhh when the denial comes first and the accusation needs the final word.

This is a just under one second voice clip of Houshou Marine saying dauto, a word that translates to doubt, with the Hologra English subtitles rendering it as she sus. It feels suspicious and playfully accusing, like calling out a friend mid lie without getting serious, and it lands as a quick, teasing reaction rather than an angry one.
