Place it near the end of a reaction sequence, after the surprising behaviour has been shown and just before the payoff. Open with Sudden Suspense to build the moment, then follow this clip with Oh My God Wow for extra disbelief, or close with Nelson's Ha-Ha for a sharper comic finish.

This is a short spoken reaction clip built around the line 'What a character?', delivered in just over a second as a dry, knowing aside. It lands with amused disbelief, the kind of mock admiration you give someone whose behaviour is too dramatic, odd or theatrical to ignore. It works as a quick verbal eye-roll, sharp enough to punctuate a moment without needing any extra explanation.
