Sam and Dean Winchester brought the Apocalypse upon us whilst trying to save others from Supernatural creatures.

Is Cleo going to hold them back during their hunts or help them out more than they could realise? And most importantly, what happens when Castiel and Dean admit their feelings for each other, and when Cleo and Sam do the same?
