Without giving away any spoilers, this is the point where the #&@* hits the fan. The Trinity team has continued their senseless violence and begin to attack civilian targets. The Ptolemenos crew and the four Gundams decide to intervene, considering Trinity to be promoters of war and destruction. The plot threads that have been woven during the first season really begin to play out. We soon find out more about each characters past and explore the relationships of some of the principal characters to each other.
I recommend watching in Japanese with English subtitles due to the amazing talent that Sunrise seems to find for their Gundam franchise. On par with Gundam Seed (not Destiny) as far as the quality of the story and voice acting but with far superior animation. Awesome series!
