Many are the rants I have made about the subject, and there are many to come: I love that Rhen always has a choice with Dameon. There's never any forced proximity, never any coercion. Rhen chooses him for her band of adventurers. She chooses to spend her free time with him in the manor, she chooses to try his gentler tactics on Mount Orion, she chooses to trust him in the Dreamworld, and not because she has to. She never has to with him, she *wants* to.
It's the whole "on purpose, on purpose I'm going to love you!" and it's also the fact that he respects her and trusts her to make her own decisions, to the point that he gives her the choice even when everything he ever cared about hangs in the balance. Even when he himself is a prisoner with no hope of rescue.
And she chooses to free him. And he chooses to follow her, all the way out of the demon's lair and through the mists and across the Eldredth and over the threshold of mortality itself. And she chooses him to live and die by her side.
And he says yes, not because he has to. He never has to with her, he *wants* to.
And for some reason all of that is symbolized to me by her putting a flower crown of her own making on his head. I (finally!!) drew them in my interpretation of the armor they wear in the game. I see Rhen's cover art "armor" as sort of like a uniform, good for padding and removing arrows in some places, and she wears the actual armor over it (the Zurvan armor, in this case). And Dameon is wearing the cloak of death, and it has chrysanthemums embroidered on it because Symbolism and also I just like flowers (if you couldn't tell XD). This piece is set near the end of the game, I think after the final battle on the way to Aveyond, but maybe before, on the way to Veldt or on the way back from Thais. I'll let you choose;D
