Battlestar Galactica, Season 4

[150,000 years later, in present-day New York; Virtual Six and Virtual Baltar are reading a National Geographic Magazine]

Virtual Six:
[reading] "At a scientific conference this week at the Smithsonian Institution in Washington, the startling announcement was made that archeologists believe they found fossilized remains of a young woman who may actually be Mitochondrial Eve. Mitochondrial Eve is the name scientists have given to the most recent common ancestor for all humans now living on Earth. She lived in what is now Tanzania, over 150,000 years ago."

Virtual Baltar:
[Smiles] Along with her Cylon mother, and Human father. [The two walk amongst the crowd, seemingly unnoticed]

Virtual Six:
Commercialism, decadence, technology run amok. Remind you of anything?

Virtual Baltar:
Take your pick. Kobol. Earth...the real Earth, before this one. Caprica before the fall.

Virtual Six:
All of this has happened before.

Virtual Baltar:
But the question remains, does all of this have to happen again?

Virtual Six:
This time I bet no.

Virtual Baltar:
[Stops] You know, I've never known you to play the optimist. Why the change of heart?

Virtual Six:
Mathematics. Law of averages. Let a complex system repeat itself long enough and eventually something surprising might occur. That, too, is in God's plan.

Virtual Baltar:
[Serious] You know it doesn't like that name.[Six gives Baltar a defiant look] Silly me. Silly, silly me. [The two walk arm-in-arm off into the streets.]
