Place it immediately after the shocking statement in a reaction edit, so it answers the line rather than introducing it. Open with No No Wait Wait to stall the moment, then follow with this clip, and close with Oh My God Wow for a second reaction.

This two-second clip is a single Italian voice asking, in disbelief, how someone could say such a thing. The delivery is sharp and incredulous, with the emphasis landing on the accusation itself. It feels like a stunned reply in the middle of an argument, half offended and half amazed that the words were said at all.
