I totally agree with you, he might even have sexual desire, since I’m this family it doesn’t seem to exist the taboo of familial links, but that’s not what matters for him, he doesn’t need to satisfy those desires, but his need to experience being a receptor of those strong emotions is an obsession for him
Okay, so apparently I got way different vibes than everyone else in this chapter? I'm just gonna put together what I commented on a few posts and some other thoughts.
Is Fontaine interested in Roxanna sexually? Yes.
Is Dion? No. Roxanna points that out, and I don't think that's supposed to be a "oh silly Roxanna, he totally wants to bang you" moment. She is very aware that he wants him to be in her heart. He wants her to care about him. But that is not physical at all.
Roxanna loved her twin brother. She loved him so much that in this house where you're supposed to hide weakness, she cried because she lost him. That fascinated the HELL out of Dion. Someone loving another person to that point was crazy.
Let us remember: Dion's mother does not love him. At all. She hates him. That love Roxanna had for her brother was something Dion had never received from anyone, so now that he had seen it, he wanted it. He wanted it bad. And since he had seen it from Roxanna and knew she was capable of it, he wanted it from her, specifically.
I'm a little iffy on the years afterwards. He wanted her to break down and cry over him in frustration. By doing this, she would be crying over him. He would have gotten into her heart. Not quite the love he wanted, but still. So now I'm guessing he's gone back to the main want because of the hug, which gave him hope. He wants Roxanna to love him. Because he loves her? No. Because he's obsessed with the little girl who loved her brother so much. Does he want her to love him in a romantic way or a familial way? I don't know. Honestly, he'd probably be fine with either. He just wants a place in her heart so that he can see those big emotions from her again. Maybe even particularly sorrow and heartbreak.
So I really, really don't think this is a simple "oh, incest" situation.
