One of the most enduring and appealing aspects of Supernatural is Castiel the (now fallen) angel, and the relationship between Dean Winchester and Castiel. The first three seasons of Supernatural already had me obsessed. Season 4 came around, and Castiel, and Dean and Castiel, blindsided me. Castiel’s arrival was shrouded in secrecy–at his audition, Misha Collins was even at first told he was reading for a demon, that’s how secretive it was. I’d heard no spoilers about angels arriving on Supernatural, or about Castiel.
I had no idea what I was getting into.
