Most people here are idiots, but that doesn't mean the more intelligent of us shouldn't try to explain to them.

I still believe there is only 1 Seed Mode. We have never heard of more than one, at least not in the actual series. I don't really trust Wikipedia for anime information because any psycho otaku could conjecture anything about such a vague topic, left vague by the lack of explanation the series does on it, and it could get posted.

As for Lacus' supposed Seed Mode eyes in those episodes, I believe the animators were trying to give her a blank expression as she tries to not be saddened by all the death and killing going on around her (that she is taking part in) and accidentally made it similair to the Seed Eyes.

As for going Seed on a whim or by losing control to one's own emotions, I believe it doesn't make the Seed mode any different at all. All that does is make the pilot act differently in the battle. Calm people will act more rational. Angered ones more aggressive and bold.

As for Kira's "I didn't want to kill him" about Andy in the desert battle in seed. That doesn't mean he necessarily lost control of his emotions BECAUSE OF SEED MODE. People can lose themselves in battle and everything starts to happen so fast that you don't really know what you're doing, but just acting on your instincts and reactions. I think Kira said that because afterwards he remembered what a normal and decent guy Andrew Waldfeld really was (he'd met him face-to-face earlier) and that Waldfeld had been absolutley right about him, that Kira was still unable to control himself in battle. that was actually one of the things that made me like Kira in the Seed series, he was human then.
