Saji's sister had a pretty good deal of screen time for a side character. Sure, louise's family didnt, but they seemed to build up the mom just to make us feel bad when she died.
Trinity I always knew were going to die, and seeing how the goal of the gundams were to unite the world, what better way to unite them than to make them all unified against a common ememy, and hopefully if the enemy lasts long enough the divisions between countries would dissolve so when they finally do win, peace will reign over earth. (which is what trinity didnt understand IMO)
But then with Lockon, half the crew of the ship, and whatever other gundam piolts died, they besides the crew they all got a good deal of time.
And anyone else remember the factory on jupiter that the scientist guy talked about before gettin raped by trinity? i think that is gona play a part in season 2 as well, because nobody knew about it besides trinity (and it wasnt in veda).
Also, what happened to trinity chick? i thought she would have met up with CB but just went *poof*
