As far as I have heard. Cagalli and Athrun are just an item. They aren't engaged or married same goes for Kira and Lacus.

As for axing Cagalli. Well Athrun wouldn't be here if it wasn't for her so lets leave her in here. Also she helped negotiate the peace talks between Zaft and Earth. She can't be too ignorant if she is the leader of Orb right? I can only wonder if its in Orb where the Savior Gundam will be introduced. Although officially its said to be a Zaft suit are they hiding it on Minerva. I keep hearing Orb when ppl talk about it. Anyways I look forward to the reunion of Athrun and Kira. And hope they get Kira in a mobile suit again soon. They are gonna need him when those Windams start getting produced.

To note people call shinn a whiner and a cry baby. When has he done this beside voice his dislike and view on Cagalli's statements? I don't see Cagalli as being ignorant either. They both have points being made and both have their personalities. Cagalli just gets thrown back abit I think.
