Put it immediately after the confusing reveal, then follow it with a Funny Ha Ha Laugh to release the tension, or lead into it with a Ba Dum Tss Drum Sting when you want a slower comic setup before the question.

This 1.3-second clip is a single sung line, “tell me why,” with the last word stretched into a long, melodic “whyyyy.” The drawn-out note makes it feel frustrated and theatrically heartbroken at once, turning confusion into a comic outburst. It works as a musical reaction when a reveal makes no sense or a plan falls apart.
