Jessica: Rowena's changing people's fates. She's killing them before their time, and when a reaper shows...
Sam: She torches them, too.
Jessica: Yes.
Dean: Why?
Jessica: You'll have to ask her when you stop her. Because if she keeps this up she's going to throw off fate. The whole greater machinery of death.
Sam: That means?
Jessica: Have you ever heard of the Butterfly Effect?
Dean: Ashton's second best movie.

I've become too sentimental. That's the problem.

Rowena

I'm especially fond of Sam's impressive extensive array of hair products.

Jessica

I know you want to murder me, and I know you have good reason to want to murder me.

Castiel

Sam: She wanted to protect herself.
Dean: Yeah by barbecuing someone.

Castiel: The angels.
Dean: What?
Castiel: Maybe Heaven could help us.

You know she's right. You never go to parties.

Castiel

We didn't call to talk. The world is in danger, Rowena.

Dean

We must assemble our most powerful allies to rescue our family and confront the archangel Michael. Now he's in an alternate universe, so...

Castiel

Sam: What's the catch? What do you want?
Ketch: Protection.

Oh my god that is tragic. It's almost like a Hallmark movie, but with tentacles.

Dean

Consider this a rescue.

Ketch
