Supernatural - Can Castiel Be Redeemed? - Sera Gamble Speaks

Sera had a few things to say about Castiel...

“I would consider Cas, in the last few minutes of the finale, to have been transformed. We try to be realistic about the fact that people on this show do cross lines that can’t be uncrossed. But we examine those things in terms of Sam and Dean. They have a tremendous capacity to move forward. We always look for the chance to have redemption.”

Also a small teaser for the next season:
“We had everyone on the writing staff watch Butch Cassidy and the Sundance Kid. Bob Singer, Eric Kripke and I were really hungry to capture some of that cowboy, outlaw spirit for Sam and Dean.”
