Put this clip just after the reveal shot and before your response line, then follow it with the awkward moment sound effect for a longer pause, or swap in an anime ahh sound effect when the next character reacts instead.

A short female voice clip, just over a second long, with a hesitant uh..? that turns into a small surprised gasp. It feels caught off guard rather than scared, mixing confusion and shock in a light, animated way that reads instantly even without any dialogue around it.
