Item from Breaking Bad by Vince Gilligan
A brass bell strapped to a wheelchair — Hector Salamanca's only means of communication, and the detonator that killed Gustavo Fring.
After Hector's stroke left him paralyzed and mute, the bell became his voice. One ring meant yes. Rapid, furious ringing meant rage — usually directed at Gus, who visited specifically to be hated by a man who couldn't fight back. Walt attached a pipe bomb to the bell's mechanism. When Hector rang it in front of Gus — looking him dead in the eye with a fury that had been building for decades — the bell didn't just communicate. It detonated. The bell's final ring killed them both. It is the most famous sound effect in prestige television.
A small brass bell mounted on Hector's wheelchair armrest. One ring for yes. Furious ringing for anger. The most expressive single-note instrument in television.
