Place it as the reaction beat right after Andy's line is missed in the edit, then follow it with a Vine Boom to underline the missed line before the scene moves on. For a bigger reveal, hold the question for a beat and let the next clip deliver the answer Andy actually gave.
关于此声音
This is a short voice clip built around the spoken question 'What did Andy say?', lasting about six and a half seconds. The question is asked plainly, as if the speaker missed Andy's words and wants them repeated. It feels confused and slightly awkward, like catching only half a conversation and needing the missing part filled in.
