Damn... that explains so much! Rayek inherited Yurek's strength of spirit, his tenacious hold on his goal, whatever that goal might be. I think you're right. I think she loved him for all the qualities that she saw in him that Yurek had. She wanted him to find happiness, somehow, someway. And that's why she was always reaching out to him. It didn't matter that he didn't look at her as anything other than a mother figure. She could accept that because... well, because Savah. But she wanted him to find that level of satisfaction with his life that could lead to truly accepting love.
