Put it at the end of a reveal sequence, after Enemy Spotted sets up the danger and just before the ambush lands, so the confession becomes the punchline. Follow it with The Bomb Has Been Planted for a shooter montage that keeps the tension moving from discovery to action.

This is a 1.6-second Team Fortress 2 voice line in which the Spy calmly announces himself in a thick French accent, saying 'I am ze spy.' The delivery feels smug and mischievous, like a joke shared just before a backstab, and it lands instantly because listeners recognise the disguise-master character at once. It comes from Valve's 2007 class-based shooter Team Fortress 2, where the Spy specialises in disguises and attacks.
