For those who've watched Ep 45 of GS Destiny, I'm pretty sure you've seen Cagalli with her bare ring finger, a subtle hint that the AsuCaga pairing is about to go down the drain... and Athrun's 'entrusted' to Meyrin's care in space since Cagalli is staying behind in ORB...
What do you guys think? Will there still be an AsuCaga couple at the end?
