'Supernatural' Season 9: Actor Misha Collins Returns as Castiel in Episode 6 'Heaven Can't Wait' [VIDEO]

Fallen angels are becoming restless in taking Castiel (Misha Collins) into custody as shown in the released promo video for "Supernatural" Season 9 Episode 6 titled "Heaven Can't Wait" scheduled to air on Tuesday, November 12. In the upcoming episode, viewers will get to see the angel-turned-human once again and find out what he has been doing after Dean Winchester (Jensen Ackles) told him to leave the "Men of Letters" bunker.

The preview video shows Castiel still struggling with human life as an employee at Gas-N-Sip. As the number of "exploding victims" increase, Castiel and Dean meet up and help in investigating the case that a "no ordinary angel" caused.

Additionally, the Hollywood Hills spoiler report on Episode 6 reads: "Dean will know that he needs to keep Sam/Ezekiel away from Castiel, so he will tell Sam that he and Kevin need to stay and work with Crowley to decipher the tablet. Crowley is going to agree to help Sam and Kevin, but in return, he is going to ask for one phone call to Hell."

Another upcoming "Supernatural" Season 9 episode spoiler report claims that a flashback will reveal Dean's old flame and a shocking secret during his youth. The Enstars report about the upcoming Episode 7 "Bad Boys" read: "Sam (Jared Padalecki) uncovers a shocking revelation when Dean (Jensen Ackles) gets a ghost-related call from Sonny (Blake Gibbons), an old friend who runs a home for delinquent boys. As it turns out, Dean spent some time at the home - unbeknownst to Sam - after getting caught stealing food."

In an interview with Huffpost TV, executive producer Jeremy Carver has teased the fans on Dean's past. "I just would say that... I'm going all the way back to Episode 1 of the series -- as we've always seen Dean Winchester, in terms of his approach to the life, approach to the hunting, it may not have always been that way," Mr Carver stated.

The executive producer further added: "I think, especially after nine years, we all tend to put our brothers and the various supporting characters into certain boxes that we tick off: This is who they are, this is how they would act and I think any time we can find a piece of the past that maybe makes us look twice at our characters, and maybe adds a couple extra layers of complexity, is always fun."

"Supernatural" Season 5 airs Tuesday nights at 9 p.m. ET on the CW network.
