I was watching OotP and I don’t even care about context I just want a scene where Cas has to leave his vessel for whatever reason and his grace is shown like demon smoke and it wraps around Dean like Hermione’s patronus. Just imagine that.
The first time Demon!Dean ever smoked out of his body was because he had heard a rumour that a bunch of other demons were going to be attacking his brother. Dean didn’t want to intervene, he just wanted to watch his baby brother in action. So he left his body in a motel with strict instructions that the room was not to be disturbed and began smoking his way over to Sam’s location.
But en route, a flash of blue/white catches his eye and almost immediately he recognises what it is. That’s angelic grace and it feels really familiar. He soon realises it’s definitely Castiel and so Demon!Dean follows him at a safe distance so Cas doesn’t know he’s there.
Before they get to Sam’s location though, Cas’ grace is joined by another smoked-out demon. This one feels really familiar as well but Dean can’t put his finger on why. The grace and the other smoke are twirling and twisting together, almost like they’re dancing completely invisible to all the humans down below.
Just as they reach the house Sam is fighting inside of, the grace/smoke collides with the floor and two figures stand up. Dean’s smoke settles itself down onto a nearby tree so he can see what Castiel was doing flying with another demon.
And then he sees her.
All 5ft4 of concentrated, beautiful sass stands up and the pair make a block between the house and the forest.
“You ready for this, Clarence?” She says to him with a sly grin on her face. “This is no different to any of the other times we have protected Sam and Dean.” Castiel replied, handing Meg an angel blade and pulling one out for herself. “Except this time Big brother’s not here.” She tells him, dropping down into an attacking stance. “Yes. I know.” Castiel says, a note of sadness and regret in his voice.
That’s when a new sea of demons attacks them. Castiel and Meg destroy every single one while inside the house, Sam is still battling the three on his own. He keeps calling Castiel’s name but is getting no answer.
Dean sits on his tree, completely amazed. Is this the reason Castiel didn’t always answer their calls? Was he protecting their lives and giving them a break with Meg fighting at his side?
