Now that I’ve just finished seeing Razor, there is one scene in particular which brings up some interesting questions:

1) How did the Guardian know Major Shaw?
2) Why did the Guardian tell Shaw what he knew about Kara Thrace, even though they were both going to die when she set off the nuke to blow up that base ship?

It’s very, very possible that the Guardian knows who the Final Five were all along...and that he’s been around for a very, very long time...even prior to the exodus of the Thirteenth Tribe from Kobol to Earth.
“All of this has happened before, And all of this will happen again...again...again....”

You need to read the book that came out and was handed out at ComiCon.  It adds more to the mystery.  It’s called THE CYLONS SECRET

As I live and breathe, Semaj, where you been?
