I dont really mind the Shinn x Luna thing, but i feel that it was wayyy too rushed and came out of nowhere. If they had more screentime together and more development with each other, then maybe i would like it. Also, another thing that bothers me is that how Luna kisses Shinn after Shinn just shot her sister.
But i guess its better than going beserk than Fllay did, so im fine with it.

Athrun x Cagalli - I guess they still like each other. This couple is still there. Theyre trying to get back to where they were before, so im guessing they'll end up fine.
