Battlestar Galactica Season 4: The Oath + Blood on the Scales

I am so happy for these episodes, a two-parter that started with The Oath and ended with Blood on the Scales.  I'd still say that Revelations was the better episode, but these two are so far the best "bottle" episodes (to use the parlance from The Next Generation companion) of the season.  By that I mean that they didn't do a whole lot to advance the story arc, but they had killer action.  They reminded me a lot of the Pegasus arc.

So as at the end of the last episode, Gaeta and Zarek are up to No Good.  Gaeta is angry about the Cylons joining the fleet, and Zarek - well he just wants to take control of the fleet altogether.  They begin a coup, and take over the Galactica with a surprising show of force; Gaeta is disgusted by Zarek's methods, and is trying to keep bloodshed to a minimum.  But, Zarek explains, that's impossible if you want to actually take control.

Some cool things happened in this episode:
- We finally see Zarek for what he is: a monster.  He was introduced as a revolutionary prisoner in season 1, and despite some glimpses of a good person coming through, he's finally revealed himself as the villain.
- Some awesome action sequences for Lee - been a long time coming since he dropped the uniform for the suit.  I doubt he's going to re-enter the military, mainly because...
- Zarek murdered the Quarum, so Lee is the last remaining member.  I think that makes him Vice-President.

And quite possibly the finest moment: Roslin, aboard the Cylon base ship, is under the impression that Adama is dead and the revolutionaries have won.  Desperate and angry, she unleashes everything on Zarek:
Do you hear me? I will use every cannon, every bomb, every bullet, every weapon I have down to my own eyeteeth to end you. I swear it! I'm coming for all of you!

You have to see the clip for yourself if you haven't already - it's awesome and scary.  The episode also marks the end of Zarek and Gaeta - a shame on two counts.  For one, Zarek was a good foil for the President.  I doubt there will be much conflict on that front beyond "what do we do with the government?".  Two, Gaeta was a good character.  Well, that's pretty much the only reason for number two.

Looking forward to the next episodes, which look like "answer" shows.  Previews say that Anders (one of the final five) starts remembering everything, and Ellen is resurrected.
