Great comment on my original Battlestar Galactica post, from rebelsnoopy:

From reading peoples theories about who the last Cylon is. People always assume that whomever it is will suffer while they are seeking redemption.

Hybrid prophecy/Razor: “And the fifth, though still in the shadow yet clawing for the light, hungry for redemption, that will only come in the howl of terrible suffering”

I suggest that the last cylon wont suffer.

But that someone else in the fleet, and I really think the people in the fleet will suffer. There will be another terrible tragedy and this last Cylon will do something incredible to save the Colonial fleet. Therefore redeeming him/herself.

That is exactly right.

The last cylon isn’t hungry for redemption for something they did wrong… they are hungry for redemption for what the Cylons did by committing genocide against the 12 colonies.

My guess is that these last two episodes of the half season get us to the reveal of the fifth cylon.  I then believe that the last 10 episodes of the final season will be the story arc around Earth & resolution.
