10 Best Castiel Quotes in 'Supernatural' Ranked

For a character that was only supposed to appear for a total of three episodes, Castiel (Misha Collins) became one of the most beloved parts of Supernatural, to the point where fans couldn't imagine the show without him. Instead of just the intended number of three, Cas was present for almost 150 episodes between seasons four and fifteen, often mentioned even if he didn't physically appear on screen. He was so loved by fans that his absence for most of the seventh season left them incredibly unhappy and beyond excited when he returned midway through.
