Supernatural- s15 e18

 Thoughts / ideas on this episode.

Understand, I get those who ship Destiel. I don't dismiss it at all. I just do not view it as such.

The scene of Castiel telling Dean "I love you" before allowing the Empty come and take him away to also take Billie. I see it, as with the entire series with the interaction between the two, a family/ brotherly love from it.

Angels, take as they are not just male or female,would take on a vessel that could hold them in the series.  There is no sexual orientation to them at all. If you recall throughout the series of supernatural, they have taken on many various vessels. 

Raphael, was a female and a male vessel at different points of the series. As well as Castiel himself, being a female way back in the older era time period. He just happened to pick out a male vessel from Jimmy this time around. Also, let us not forget, he took on Claire as a vessel temporarily as well. 

Hannah, was even a female and then a male. Then, a female once again. 

Now, getting back to the scene-

Dean took the time to guide and teach Castiel, as he had with Sam over the years. Only, Castiel needed teaching of other things.

He "opened his eyes" as Castiel said. To me, no one else took the time like Dean has to show him the world as he knows it. Also, maybe perhaps Castiel never allowed anyone else to take the time to show him. It was a brotherly taking under his wing. Castiel now sees the world in a new light, thanks to Dean. And he loves him for that. It isn't necessarily a sexual tension of a love, but more of an appreciated and family bonding love.
