Battlestar 4.15 "The Oath"
Since the second season of Battlestar Galactica there has been many hints towards the idea of the fleet being divided between those who accept the cylons living among them, and those who want to see all of the Cylon race destroyed. The main characters have always sacrificed and worked diligently to prevent such a division, because the logical conclusion was that such a divide would cause a civil war amongst the last surviving humans, and thus the whole race would be wiped out.
It looks like this show is not destined to have a happy ending. From the most recent episode 'The Oath', we see that Civil War finally begin, in what show creator, Ronald D. Moore, labels the first of the 'Mutiny' episodes. 'The Oath' hearkens back to the incredible tension at beginning of the second season as well as the tension in the first half of the third season.
From now on, throughout these 'Mutiny' episodes, there won't be a moment to relax, any main character could be killed off, and judging from the cliffhanger ending of this episode, it is very likely at least one character will.
Many characters were out of character throughout the beginning half of last season, as well as the first episode of this season. This ranged from Starbuck, who was unsure if she was a Cylon or not, to President Rosalyn, who has lost all hope of humanity surviving and wants to "live a little" before she dies. Once the shit hit the fans in this episode, however, Starbuck and Rosalyn were back to their kick ass selves, both in scenes that fellow fanboys would call "Geek Out" moments.
When Apollo is held at gunpoint by a group of Mutineers, Starbuck rushes in, guns a blazing, first shooting the man with the gun at Apollo's head, and then shooting the large mutineer who tells her there is no way she can take all of them out.
Rosalyn is back, sporting her long brunette wig and her black framed glasses, dressed as professionally as she has been for the majority of this season. Taking back the reins as the President of the colonies, she sends a message across the fleet explaining how the members on each ship should not give into their fears, and that the fleet must work with the Cylons to ensure humanity's survival.
Her voice over the intercom ignites as much excitement as Starbuck shooting a fellow crew member in cold blood. Even Adama and Tigh get their chance to kick a little ass, escaping from their captors, but not without throwing in a few action figure poses.
As this episode so clearly shows, The Cylons are not the biggest threat to humanities survival- humanity is! There are only a few more episodes left. So we shall see, does Humanity go out with a Bang or a whimper? Or is it possible that there might be a light at the end of this very dark tunnel?
