Helios is for Medeia because as like-minded manipulative killers and their history, I feel they have a deeper relationship and feelings that only they can understand. For Psyche I believe the red hair that came in. I originally thought he would like Medeia snce he was looking for her but that went out the drain when he attacked her instead. Anyway I can guess he hates souls or auras that have a killing nature so Psyche's gentle and pure aura would attract him and draw him in since she would seem so different from before. Plus she has a good image amongst the people as well as her divine power so she would compliment him since he is a powerful mage or something but has a bad reputation among the church
hold on who the ml?
