1) First, KOS-MOS says she's the Will of Mary after being awakened. Then she merges with T-elos and claims she's Mary now. Her eyes turn blue.
But then at the pivotal moment, when she takes Shion's pendant and shatters it, she suddenly claims that she is KOS-MOS, not Mary. I don't understand. And she remains with the red eyes until the end. Even when she dies, chaos calls out "KOS-MOS!" rather than "Mary!"
I have a feeling that it was really significant and I totally failed to grasp it. I mean, she rejects being Mary when she chooses to respect Shion's wishes over 'saving the world'. What did the author want to say by that?
It just makes no sense. If Mary and Shion were close in some lifetime before, then shouldn't Mary claim that she chooses Shion (presumably out of love) because's she's Mary? Or does her claim to be KOS-MOS implies that KOS-MOS feelings for Shion proved to be stronger than Mary's ever were?
2) In that room that preceeded KOS-MOS' awakening, they couldn't find the way further without awakening KOS-MOS. The room was said to be sealed by Mary's will, so it was imperative to awaken Mary's Will.
My question: if that is so, how in blazes did Wilhelm get past that room and was waiting for the group further along the way?
I'll post more things that confuse me if I remember more.
