Ricky, Dicky and Dawn wears safety suits designed by young inventor Simone, mistaking them for invisibility suits, and hide when Nicky and Simone are about to see them. It's revealed through Simone that the suits are emotion-activated and inflate like airbags. While intended for situations like fear before an impending car crash, they instead activate when any emotion is felt at all. In this case, the trio inflate when they're moved by Nicky saying they're the most honest people he knows, instantly exposing themselves.
