Place this clip as the reaction beat right after the reveal in your edit. Lead into it with the sudden suspense sound button for the build, then follow it with the oh my god wow sound button if you want a second, bigger reaction from another voice.

This clip is an 11-second spoken Portuguese line, 'Meus olhos vêem, mas não acreditam,' delivered as a dramatic reaction take. It gives off stunned disbelief mixed with comedy, the feeling of staring at something real but completely absurd. The drawn-out delivery makes the incredulity land harder than a short gasp would.
