There are only three episodes ofSupernaturalleft.

And if episode 17 is any indication, there’s a lot of drama ahead.

But what they didn’t realize is that they were playing into Chuck’s ending.

“We pick up right [where we left off],” saysMisha Collinsof next week’s hour.

“This is almost like a two-part episode 17 and 18 really flow into one another.”

“In 18, we do get Cas' chapter,” says Collins.

“[In episode] 17, it feels like Cas is there, but he’s not central.

[In episode] 18, he becomes much more central.”

But with Jack on the verge of death, what does episode 18 have in store?

Jensen Ackles has already told us the hour is “monumental” for the series, and Collins agrees.

“It’s monumental, it’s tragic, it’s I think pivotal,” says Collins.

“It’s a sad episode.”

Then again, when there’s only three episodes left, isn’t every episode a little sad?
