Losing a string of characters is never easy.

As you are all likely well aware, Supernatural Season 12 featured a lot of death as it came to a close and fans have been questioning the direction the show will go in when it returns.

The cast and crew had a lot to talk about when they hit up San Diego Comic-Con for an exciting panel that gave a lot of information away.

With Castiel seemingly dead, fans questioned whether his appearance at Comic-Con meant he was still part of the show.

“Misha [Collins] had become a bit of a prima donna,” EP Robert Singer joked about Castiel’s death. “We say when we write these things, you have to go where the story takes you.”

Collins added, “Take the story where it went, but I’m not going away.”

So, there's the answer. Castiel WILL be back, but we'll need to stay tuned to find out more on the matter.

With Mary and Castiel seemingly out of the picture, there were questions about how the brothers would deal with the demon spawn that is Jack.

“Obviously, with mom being gone and Cas and all of this turmoil the brothers find themselves in, now they have this person, this thing, this entity [that] in Dean’s mind simply has to go,” star Jensen Ackles shared.

The actor does not see “why anyone would want to see how that [half-demon child] works out. Dean’s a bit more practical: ‘I have an idea. Let’s shoot it in the face.”

With all of the death, you would think that some of them would stick, but it appears that Mary is most definitely not dead.

“Dean is pretty sure that’s curtains for mom,” Singer previewed.

“While he’s bereft over that, he’s ready to accept that.” But Sam, as always, is “holding onto the fact that she could still be alive. That’s a problem between the guys” as they bicker about which of their many problems to take care of first.

Also, it has been revealed that Mary will come across some past characters in her apocalyptic world.
