"Meanwhile, on BSG, the "head" Baltar and Caprica Six show up in New York a squillion years after the show's events are over, and inform the audience that God really did arrange the big Cylon/human struggle. As Head Six says, "Let a complex system repeat itself long enough, eventually something surprising might occur. That, too, is in God's plan."

In other words, even if things go in cycles, eventually something new will emerge. That's not too different from this conversation between Jacob and his evil brother, in "The Incident":

The Man In Black: They come. They fight. They destroy. They corrupt. It always ends the same.

Jacob: It only ends once. Anything that happens before that is just progress.

The difference is, Lost sets up that dialectic a year before the show ends, and has spent the past year exploring it."

It only ends once.
