Right now I'm rewatching Season 4 of Supernatural. My perspective as I watch it again has changed quite a bit; I'm finding myself with more opportunities to appreciate the character development and inner conflict that occurred during this season. The first time around, all I could concentrate on was the thrill of the ride as the season built up to its conclusion.
So, to interpret my new insight into the characters, I've decided to compose a few paragraphs from the POVs of Dean, Sam, and Cas—sort of a "psychological portrait" of each of them, I guess.
Spoilers for the first four seasons of Supernatural.
Introduction
In This World, Ye Shall Have Trials and Tribulations
As the demon Lilith breaks the 666 Seals, intent on raising Lucifer, the forces of Heaven and Hell gather to do battle. In the midst of spiritual warfare, both angels and demons have fixed their attentions on two brothers, Sam and Dean Winchester. Neither one knows why, but both can sense that their intended paths lead in very different directions. One is hailed as the champion of angels; the other as the harbinger of evil incarnate. What Heaven and Hell don't realize, though, is that no amount of manipulation can break the human spirit. Love and the bonds of brotherhood cannot be torn apart, not even by the Devil himself.
