Perfection Moment

Not at all sliiiick.

This is when somebody is given 100% of the skill required to finish the Big Dramatic Finale because the person who was supposed to do it instead Got Sick. They can't screw up or else The Emotional Moment and Big Speech would have been all for nothing. And God forbid that ever happens.

Despite being shown failing almost all the time at what this thing is, the understudy still pulls this one great big feat off and ends the story on a happy note. This is probably Plot Said So at one of its greatestundefined moments, being played almost perfectly in this very moment.
