Agonizing Reunion is music in Sly Cooper: Age of Thieves. It is the music that plays when Ven St. Claire makes his wife, Belle, possess Penelope.
Description[]
This music first uses several Victorian England-themed instruments for the majority of the tune. It changes to insane-sounding carnival music when Ven's hatred and madness begin to override his better judgement. At first, the song starts off happy, but it slowly begins to get darker and grimmer as the tune progresses, eventually becoming creepy and evil-sounding when Belle is no longer possessing Penelope's body.
