Maybe he didn't even have a connection with her and whatever she did was enough to use his abilities. After all, she was using them in conjunction with his own methods; maybe if she had tried to twist their use for something else he would have taken notice.
We truly have no idea without asking him ourselves, and no--I don't believe anyone knows how she forged that link. But. I do know a little about the day-to-day Solvunn rituals. Prayer and bribery.

I don't know what one would offer to try and reach Nikodaemus nor do I know how a response would look, I'm just saying, maybe if you really want answers you could try.
