Molly quotes from Supernatural

Molly

Isn't this argument a little archaic? Men can ask directions these days.

No we can't. It's against our genetic code.

Dean

Did he look like he... lost a fight with a lawnmower?

Molly

How did you know that?

Dean

Lucky guess.

Molly

I don't understand how a guy like this can turn into that monster.

Sam

Well, spirits like Greely are, uh, like wounded animals. Lost... in so much pain they... they lash out.

Molly

Why? Why are they here?

Sam

There's some part of them that... that's keeping them here. Like their remains, or, um, unfinished business.

Molly

Unfinished business?

Sam

Yeah, uh, it could be revenge. It could be, uh, love, or hate. Whatever it is, they just hold on too tight. Can't let go. So they're trapped. Caught in the same loops. Replaying the same tragedies over and over.

Molly

You sound almost sorry for them.

Sam

Well, they weren't evil people, you know. A lot of them were good, just something happened to 'em. Something they couldn't control.

Dean

Sammy's always gettin' a little J. Love Hewitt when it comes to this. Me, I don't like 'em. And I'm sure as hell ain't makin' apologies for 'em.
