Be it Save Castiel or Team Free Will, the below are just a sample of the multimedia-expressed love of these characters, be it love of kinship, romance, or camaraderie.
Team Free Will: the ex blood-junkie, the highschool dropout, the holy tax accountant, and the archangel in witness protection. Not exactly your typical heroes, and it kind of shows.
The author of this piece said it best: "I tried to capture the overall themes of the show; family, camaraderie, brotherly love, self sacrifice. These people will literally follow each other into the dark, no matter what the consequences. The concentration is on the battle the brothers are currently facing, being stuck between Heaven and Hell. I'm glad our three boys are Team Free Will, aren't you? :)"
A beautiful vid that whether taken as a Destiel view of Dean and Castiel, or a profound bond view, speaks of their connection, and of Dean's belief that he - as Cas once said - does not deserve to be saved.
