While Gundam Double O has kept consistently to its talk-first-all-action-later kind of storyline for each episode, I'm starting to think that it's going to get much more complicated and interesting in the episodes to come. So far, for the 'talk-first' ^^ section, each episode only explain more on the background of the different characters, and very little, almost nil on character development. Setsuna's characteristic never changed much so far, and the same goes with Lockon, Tieria and Allelujah, even though Allelujah temporarily did lost his Gundam Meister coolness in the last episode. In this episode, we get some to know that Celestial Beings, AEU, PMC alike, all the characters are somewhat connected to each other, and how will their intertwined relationship be developed is what I'm very interested to find out in future episodes.
On the other hand, we get to see more of the two girls from Ptolemaios: Felt Grace and Christina Sierra. Personally, I like Felt more ^^
Felt is the pink-haired girl on the right ^^
Also, Patrick Corlasawar, the first victim of Exia makes a come back in this episode, but this time, he faces Gundam Virtue. How did he do? You have to watch this episode to be 'amazed' XD
In terms of character appearance, this episode managed to put almost everyone significant in Gundam Double O (so far) onto the stage, with the exception of Kinue Crossroad, Saji's reporter sister. As a result, some people just came on screen with one line of script, and no more. If you go to get yourself a drink or something, you'll probably miss several people in some scenes :) At the same time, a new character is introduced as well, and a very important one as well.
As for the action, well, make sure you don't blink your eyes too much, or you'll miss out a lot!
Other key points of this episode include:
(1) All weapons free!
(2) Headshots XD
(3) 130 cannon fodders XD
(4) Shogun Enact!!
(5) Setsuna's sifu (teacher)
If you don't mind the Chinese subtitle, you can watch this episode on Tudou.
