Although I say “new” summaries, there isn’t really a whole lot of new information:

Episode 16: Prelude to Tragedy

The reason for the sudden withdrawal of the anti-Celestial Being A-LAWS offensive is because of the coup d’état that had broken out in the Federation.Having been informed about the coup by Katharon, piloting the 00, Setsuna heads toward Africa. But, there waiting in a new unit and a ready stance is none other than Mister Bushido.

Episode 17: Within the Scattered Light

With Ptolemaios’ repairs still not completed, Celestial Being is unable to break the deadlock in their disadvantageous situation. In the middle of things, although Setsuna is injured, he rises to the occasion and sorties in the 00. That Setsuna offers encouragement to Saji.

[EDIT]
This is totally unrelated to anything but I just need to whine: I have to write a sakubun on “what it means to be a productive member of society” for Japanese class later today. I’m still not done with it  and I have class in 5 hours :<
