Place it just after the wake-up shot, before the reveal of the risky plan, so the warning sets up the trouble. Follow it with a short reaction for the fallout, and keep a second reaction ready for the moment the plan goes wrong.
About this sound
This just-under-seven-second Portuguese clip has Bart waking up and realising the guys around him are up to no good, delivered as a quick spoken warning. It feels wary and tense, with a comic edge that comes from the sudden realisation rather than a shout. The line lands as an alert, the kind of moment that makes a listener smile while bracing for trouble.
