Place it right after the reveal in a short edit, with Sudden Suspense just before it and Oh My God Wow landing straight after the reaction. That order gives the moment a clear rise, a peak and a payoff, and keeps the edit moving without another beat crowding it.
About this sound
This under-two-second clip is a raw, drawn-out shriek that breaks into a rough, spluttering burst, like a scream cut short by a sudden choke. It feels frantic and over the top, the kind of noise that makes a wild moment feel even wilder. It works as a sharp jolt of disbelief, turning an ordinary reaction into something messy and hard to ignore.
