Dean is now a demon. Is he the same old Dean or his demonic side took control over him and there's no turning back? Hell falls on a temporary calm with Crowley being their only leader, but for how long? And the angels, now having the Metatron caught which path will follow - will Cas be their new leader or someone else will come to take the domain of Winchester's favorite angel?
Dean turns 18 and Cas promised in a strip but when the times comes to do it things change and Dean is the one doing it. One thing leads to another and the strip tease soon ends with them having sex.
