Well, I didn't think that move was all that good, either, I meant that she had a good point about her reasoning on it. And I can't blame you for not trusting Nena... she's rather crazy, after all.
As I said it seems that Wang Liu doesn't care about the people. She just wants to change the world. If she has to sacrifice millions of people, I think she will do it. At least, that's what i think about the current Wang Liu. Now it could change if something bad happens to her, like losing her brother...
Nena, is a bad person. What she did in the first season is unforgivable. Not matter the circumstances or her past, whatever, nothing can excuse what she did to Louise family at least. It's like what happened in EF this week. Whatever the past of a person, what Amamayia sensei did is unforgivable. It's not because a person is sad and had a life full of sadness that it gives him/her the right to do something bad to an innocent people.
As for betraying her to the Innovators... well, I had this big thing written down about how the Innovators going after Wang wouldn't be a good move, but as I was writing it down, it became clear why it would be a good move on their part. :V
Ribbons is not aware that Wang Liu is helping the CB, nor that the Gundam 00 exists thanks to her. If he learns that from a person like Nena, he will try to destroy wang liu.
And yeah, I can see him sacrificing himself, even if he doesn't agree with her methods on the war. Sibling love can do that to a person.
That would be a cliché, but it's the most obvious possibility imo <_<
Nena's got a pretty high chance of dying herself, too... I just wonder how that would happen... either Louise will kill her (somehow) or Ali would kill her. At the very least, I can see a Nena vs. Louise fight in the future.
I think that Ali will kill her, while Setsuna will try to save her. And she will die after that after a little discussion with Setsuna. Saying that she is sorry etc. =p. That's how I see it at the moment
About Louise, it seems that Andrei has an interest in her <_<. And I don't really like Andrei
