Scully:
You've always said that you want to believe. But believe in what, Mulder? If this is the truth that you've been looking for, then what is left to believe in?
Mulder:
I want to believe that the dead are not lost to us. That they speak to us... as part of something greater than us [...] And if you and I are powerless now, I want to believe that if we listen, to what's speaking, it can give us the power to save ourselves.
Scully:
Then we believe the same thing.
Mulder:
Maybe there's hope.
