Place it right after the reveal in a short edit, letting the reaction carry the cut before the next clip starts. For a bigger build-up, open with Sudden Suspense, then follow with Oh My God Wow for a second reaction to the same moment.

This short clip is a single voice stretching out an 'Oh my God' in disbelief, holding the vowels until the shock lands. It feels like catching something unbelievable in real time, half laughing and half stunned, with the emphasis doing all the work. That mix of amazement and comic disbelief makes it easy to recognise in an instant.
