Sam Winchester:
Anyway, Shtrigas can feed off anyone, but they prefer...

Dean Winchester:
Children.

Sam Winchester:
Yeah, probably 'cause they have stronger life force. And get this: "Shtrigas are invulnerable to all weapons devised by God and Man."

Dean Winchester:
No. That's not right. She's vulnerable when she feeds.

Sam Winchester:
What?

Dean Winchester:
You catch her when she's eating, you can blast her with consecrated wrought-irons, uh, buck-shots or rounds I think.

Sam Winchester:
How do you know that?

Dean Winchester:
Dad told me. I remember. [Sam gives Dean a look]

Sam Winchester:
Oh. Huh. So uh, anything else Dad might've mentioned?

Dean Winchester:
[evasive] No, that's it.
