all will be solved when its revealed souls are split in mind-body-heart/soul
they said there will be a twist in regards to silvia. not mikono is not silvia but a split of her which is what the whole 3 way split probably is. so amata will get either mikono or zessica. kagura won't get entire silvia just parts of her like maybe shu shu. zessica will get solar aquarion
and do the go tight dance with it.
in this episode we see the conflict of how to face a situation amata was in. the difference of opinion of mikono and zessica. just like how normal people have a conflict between mind and heart.
it is up to you to think about who is heart and who is mind-body. the heart imo is zessica, mind-body - mikono-shushu. since the anime is still gong on it is likely that they switched places of who is heart and who is mind later on in production.
