Supernatural Season 10 Spoilers: What's Next for Castiel?

The latest Season 10 episode of Supernatural did not feature Castiel, but everyone's favorite angel is faring better, at least temporarily, after Crowley replenished his grace with more stolen from another angel. But what's next for the trench coat wearing Cas?

The "Ask Ausiello" column at TVLine has an answer.

Question: TVLine.com is the first site I check in the morning. You are my spoiler superhero, so I need you to rescue me. I'm desperate for a big juicy Sam-centric Supernatural spoiler. -Kira
Ausiello: Can I give you a mildly-juicy Cas tidbit instead? Crowley may have replenished his grace, but the angel still has plenty of problems. 'He's going to be at something of a crossroads,' executive producer Jeremy Carver previews, 'deciding what's most important to him and what's most important about the mission that he was sent here to do - and what that's come to mean these days. It's going to lead him on a pretty personal, pretty powerful journey.'"

We already know the stolen grace will burn Cas out eventually, so Crowley's solution was just a Band-Aid over the larger problem. We also learned some of Cas' original grace is still out there somewhere and Metatron claims to know where it is. Supernatural will likely revisit these plot points numerous times throughout Season 10.

What do you think will happen to Castiel throughout the tenth season? Let us know in the comments section.
