They have gathered to revive a the dead for self purposes but why? I'm pretty sure that the reason the Knight holds on to her is due to the fact that she understands him (I think) as no one ever did. Therefore it's reasonable that he would not want to let go of her. But the King desperately holding her just because the old Eris gives him love that's only for him... What? And what's up with the high priest? They literally talked like 5 times and as far as I remember they only talked about her colour, his mom and their blood relation there's absolutely 0 lovey Dovey moments what the fu**? 
My opinion. If you have something bad to say about it, fu** off.
