"Supernatural" fans are aware that angel Castiel (Misha Collins) turned human in Season 9 and stole an angel grace to have some powers back but it is slowly fading before Season 9 ended. The latest spoiler reports on "Supernatural" Season 10 tease that there is someone who could help Castiel with his problem and even save his angel grace.

"I think probably Metatron is key to getting Cas' grace back, and Cas knows that," Collins revealed in the Spoiler TV interview at the 2014 San Diego Comic-Con press room. However, the 39-year-old actor teased that his character will be reluctant to cooperate again with Metatron (Curtis Armstrong).

Castiel has trust issues when it comes to Metatron since the Scribe of God tricked him and took his grace. Actor Misha Collins further shared that Metatron could still resolve Castiel's issue. "Because he certainly is - as far as we know - the one who knows how to do that or where Cas' grace is," the CW star explained.

Aside from his fading angel grace in "Supernatural" Season 10, Castiel will have his mind set on BFF Dean Winchester (Jensen Ackles) who is now a demon. Collins teased in the Zap2it interview that Castiel, even though displeased to find out about Dean's new identity, will still try to help with the Demon Dean problem in the beginning of the brand new season.

However, the actor teased that the demonic transformation will cause a gap between Dean and Castiel. Collins even added that his character will not have problems getting rid of his friend because Castiel only sees Dean as a demon or a monster that "one way or another, needs to go."

Fans can also expect a personal storyline for Castiel in "Supernatural" Season 10. According to Misha Collins, the "Supernatural" characters' storylines will be intertwined but the actor's character will still have a strong and independent storyline in the CW TV series.

"It feels like we're dealing less with the massive, epic stories of heaven and hell and more with the personal stories of the characters that we've all come to know and love on the show," Collins teased. "Supernatural" Season 10 is scheduled to premiere on Tuesday night, Oct. 7, at 9 pm ET on the CW Network.
