Elda is a class A bitch but i dont know why i like her, if she becomes really unreasonable i will reconsider those feelings, and yeah i know all the "stepping on the head after pain spell" is already unreasonable but i dont know why i am not counting that.
Anyway, the little bit about how he manipulates his chains is interesting, i didn't feel he used it during the arena fight but it does make sense, and the jewel in his wrist clearly lighted now.
What Elda wants inst so difficult to grasp, she has too much personality to be an obedient princess somewhere, and her feeling for Vera (be really romantic or not) stems from the fact that he was even more caged than her but his spirit never broke down, now if she really wants to break that spirit or not that i am not sure, she sure doesn't seem to be just acting when she humiliates him.
