Cavalcanti displays a unique gesture that communicates understanding and unity among the bandits. By wiping his eyes and using an inflated cheek to create a sound, he conveys a message that silences the group, suggesting a shared language or code that resonates deeply within the criminal fraternity. This action not only captures their attention but also reinforces his connection to them as one of their own.

This gesture, reminiscent of a Masonic sign learned from Caderousse, reveals the intricate system of communication that exists within clans or groups engaged in illicit activities. It underscores the theme of belonging and recognition, highlighting how subtle signals can forge powerful bonds among individuals in such communities. Cavalcanti's ability to command silence so effectively speaks to his status and influence among the bandits.
