Stellar's not dead. This is what I have decided. She's not dead, because she's in the opening sequence too much. Sure Auel and Sting are in the opening sequence, too, but they're never hanging out with Shinn. Although, Stellar's death would make it easier for Shinn to end up with Lunamaria, thus successfully pulling her away from Athrun. But I think she deserves better than Shinn. Just not Athrun.
There are only two girls who deserve Athrun, and one of them likes Kira. Well, maybe Milly, too... I wonder why she dumped Dearka.
