Adalind's already used her powers in front of Nick and he didn't react one way or another, technically he asked her to use her hexenbiest powers. I don't think Adalind will go out of her way to use her abilities unless absolutely necessary and Nick won't have a problem with that. It will be interesting for him to find out about Rachel but I doubt he'd care all that much about Bonaparte since it was in response to him choking Adalind and it also saved his life.
I don't think Renard loves Adalind. He may have some regrets now that she couldn't care less for him and he's seen for himself that perhaps he was wrong about her not being a capable mother when he agreed to let Kelly take Diana away. Honestly, what Adalind has with Nick and Kelly, he could have had with her and Diana because at the time, Adalind had zero feelings for Nick and likely still harboured some real feelings for him. They could have been a real family, something that he was robbed while growing up but he pissed all over it because of his hatred/resentment for Adalind. She only gives him the time of day because of Diana and nothing more than that.
