Rayven left Angelica alone feeling all kinds of emotions. He had only meant to be romantic and heal her wounds but got caught up in the moment. He hadn't thought of healing her that way. She gave him the idea and when her body responded to his, he couldn't stop himself.
His demon would now not try to fight him to mark her. The demon only got agitated to mark when it felt like the receiving end was willing and when there was a clear indication of no, then it retreated. Now his fangs wouldn't forcefully elongate but they could still tease their way out if he got aroused and Angelica wasn't only afraid of being bitten but also of the fangs themselves.
Anger could also make his fangs elongate and right now a part of him was burning with something other than need.
