To drive home the revelation, the show explained her elaborate evil plan via a theme song named “Agatha All Along”, which went viral on social media after the episode.

It has since been released as an official track and topped the iTunes chart.
“If you are wondering why you were so ready for the last song, it’s because you were hearing the same song week after week,” Anderson-Lopez tweeted.
