Even before Sheppard became a series regular, Crowley felt like a core character of “Supernatural”. It’s not often the powerful demon that troubles the Winchesters, but no matter which side of the battle he’s on, Crowley is always thrilled to be around. Sheppard stole the show with Crowley’s brand of sassy clashing with the brothers in just the right way. He even gave them hilarious nicknames that have become popular with the show’s huge fan base – Moose and Squirrel! But while he’s certainly best known for spouting brutal insults and insinuations, the King of Hell also knows a thing or two about his human contact. Those emotional moments led to streaks of amazingly high scores.
Sheppard recently recalled her time on the series while chatting on a panel at Wizard World Chicago (via TellTaleTV), where he shares that such a moment stands above all the rest:
“The end of season 8 was the most fun we’ve ever had. It was really the best time for us. We shot the ending sequence in sequence and we’ve never been together more. at that time.”
The episode is referred to as “Sacrifice”, which marks the culmination of Sam having to endure a series of trials to close the gates of hell, with all the demons sealed forever. The final challenge requires him to cure a demon – and who better than their arch-nemesis, Crowley? Though he is an unwilling participant, the ritual ends with some shocking revelations from the King of Hell as he slowly regains his humanity and confesses his desire to be loved. It’s not hard to see why this moment stands out for Sheppard, especially when it’s at the center of an already incredible episode.
