The main things that need to be known for the works in this headcanon to be understood are as followed: The events of "What's Up tiger Mommy", "A Little Slice of Kevin", and "Torn and Frayed" all still happened, with two exceptions. The first being that, during the end of his time as Crowley's prisoner, Samandriel and Crowley end up sleeping together (this will be expanded in a fanfic I am writing, it's just a stubborn bastard. That's all I'll reveal on that front for now). The second being that Samandriel wasn't killed by Castiel on Naomi's orders. Instead, Crowley doubled back to get something he forgot at the warehouse, and while doing so he stumbled upon the interaction between the two angels. Crowley saw what was about to happen and, using his telekinesis, flung Castiel away into the side of the warehouse, allowing Samandriel to escape and not be killed. This act, along with what happened in the warehouse, have a serious influence on their relationship moving forward. After escaping the events of Torn and Frayed alive, Samandriel stays with the Winchesters at Rufus' cabin as he recovers from his ordeal, and during his time there, that's where his feelings for Crowley evolve
