Vena: conversely, imho they keep laying the groundwork for Zessica to be Sylvie. In particular, each time she's had a "close encounter" with Kagura there's been a little extra *something* going on, it's just not that blatant. I'm just going to guess we're getting trolled every which way and not sweat the details too much any more (...and yes, I know I've said that before).
But I do think the "inherit a legend" and "true name" stuff from episode 1 are going to be the right trees to bark up, even if it's not clear how exactly that fits into what we've seen since then.
Some comments on those spoilers:
Spoiler for Spoilers:
mayumi is right, the spoilers have it as Kagura-Mikono and Amata-Zessica...not sure where the females went (was it translated on Altair,
?).
Zuul's Newtype spoilers don't seem as strong as their English summary. Unless there's more from that article it's more like "Amata, who's *said to be* the wings of the sun" and "Kagura, who also *seems* like a person with a destiny"...so I don't think that's quite *confirmation*, unless it's taken from a longer article.
Mangaka-Chan: two of those I'd paraphrase a bit differently. The second one about Mikono I think should be closer to: "Mikono doubts herself after she wound up sticking up for Kagura, and is unable to simply reject this "past-life stuff" and the one that was hard to translate I think should be more like (loosely) "Kagura's motivations being due to past-life shenanigans jolts Amata, and he responds with the idea that the feelings and people of the present are more important than "past-life stuff".
All that is FWIW and "as I understand them", and I happily admit I only have mediocre language skills and may be getting them wrong...but those paraphrases I *think* are a bit closer to those lines. In any case, that understand of those two lines were where my facepalm-inducing scene idea came from.
