Yeah, I'm virtually certain she dug it up. (God, my memory is vague now. I used to have this stuff memorized). Weren't there visions and stuff? Doesn't this somehow lead into the episode Amore Fati? Where Mulder has those weird apocalyptic visions?

And I seem to think that either she dug up another one or it's this one that's still being studied because I think there was something about that in the William arc later.

(Boy, it's shocking to me how my memory has faded.)

Back in the day X-Files pattern was that it would have a mytharc episode basically during sweeps and then between sweeps it would mostly be MOTW. (Which probably makes it more strange in DVD viewing, but had a certain rhythem to it at the time).
