As far back as they go - Tradução em português

Contexto:

Dean: All right, say Bloody Mary really is haunting this town. There's gonna be some sort of proof—Like a local woman who died nasty.
Sam: Yeah but a legend this widespread it's hard. I mean, there's like 50 versions of who she actually is. One story says she's a witch, another says she's a mutilated bride, there's a lot more.
Dean: All right so what are we supposed to be looking for?
Sam: Every version's got a few things in common. It's always a woman named Mary, and she always dies right in front of a mirror. So we've gotta search local newspapers—public records as far back as they go. See if we can find a Mary who fits the bill.
Dean: Well that sounds annoying.
Sam: No it won't be so bad, as long as we... I take it back. This will be very annoying.
