The cast and crew of Supernatural hit Hall H at Comic-Con 2013 earlier today, with a panel featuring cast members Jared Padalecki, Jensen Ackles, Misha Collins, and Mark Sheppard, and executive producer Jeremy Carver to promote Season 9. A special highlight reel was presented to the fans, and you can watch the full video below, then read on to see what was revealed at the panel.

Executive producer Jeremy Carver spoke about the number of "fallen angels" that make their presence known this season.

"We've got lots of angels out there with lots of different agendas. [They're] lost, scared, and vengeful, and I think [the storyline] is lending itself to lots of exciting and wonderful character moments for all of our characters to be dealing with. A world of fallen angels is a dirty, bloody, scary and in some ways very human world. We're very excited to explore that. I think we can pretty much bet that the path of the fallen angels intersects with the Winchesters in some very big way this season."

Jared Padalecki also spoke about Sam and Dean's relationship this season.

"We did chose each other and to continue fighting the fight together. We'll keep fighting the fight together and you'll be seeing Sam and Dean - in this free-for-all world - we're really going to need each other more than ever."

Actress Felicia Day also made a surprise appearance on the panel, confirming she will be reprising her role as Charlie Bradbury. Here's what executive producer Robert Singer had to say about her return.

""We have big plans for her this year."

Misha Collins revealed that he is directing the 17th episode of Season 9, and also spoke about his character Castiel, who makes the shift from angel to human, which means all of his supernatural powers are gone.

"It's a remarkable shift for Castiel. Now he can pop in and basically fold laundry. So there's a shift in the dynamic here...I think for Castiel's arc as a character this season, it's going to be an immensely rich terrain to explore."

The actor also had a memorable response to a fan who asked where angels and demons go when they die.

"They go to Comic-Con."

Supernatural returns Tuesday, October 15 with the Season 9 Premiere.
