Yes, I love a great reveal as well x3
I'm thinking that his interest could be contributed to the guilt he felt about Odette 'dying' because of him. Like because he could save or protect Odette then maybe he could redeem himself by turning Rey and protecting her. And of course when she can't be turned he views that as him being 'irredeemable' and that's why he gets so pissed off about her 'not letting go'. Because he can't let go of his own past. So I see it fod the rp as not really a romantic interest, more of an interest in redeeming himself.
