Buzzed Out at Brainwave Tower

9 min

On the evening of 21 July 2026, Cassie Renard answered all seven Final Vault questions correctly in under ninety seconds, a feat no contestant had achieved in the show's eleven-year history. The production company's internal review flagged irregularities in question-vault access earlier that day and suspended Cassie pending investigation. Prosecutors allege that Cassie, through an acquaintance on the production crew, obtained advance sight of the questions and memorised the answers before filming. The defence argues that Cassie is a documented expert in the subject areas tested and that any apparent vault irregularity has an innocent explanation. The jury must decide whether the prosecution has proved beyond reasonable doubt that Cassie received leaked answers.
