There is no indication that Viktor knew how to remove Nicks powers. It just makes sense a Grimm removes a hexenbiest powers he then becomes vulnerable to hexenbiest. Only natural that the taking of powers would have a cost, something to balance the scales.
What I am wondering is the intimacy part. The scratch took a kiss. To activate the spell on Hank took sex. To remove Nick powers took sex. To return Nicks powers took sex. To regain her powers chop up a hexnebiest. To suppress her powers chop up a hexenbiest. Consuming someone is about as intimate as you can get. Even if it is only consumed topically.
The other thing I wonder about is little Kelly. There are a number of statement that let us know the Adalind in Kelly will not effect the Grimm in Kelly. The spell Adalind did to take Nicks powers was an entwining spell not a glamour like Frau Pech did. When Juliette became Adalind entwining would mean she also became a hexenbiest, which is what gave Nick his powers back. A baby is the ultimate entwining you can have. And since it was performed by a hexenbiest, like Juliette when she gave Nick his powers back. Having it do the same to Kelly would be well within the mechanics of how the spell works.
I also have this feeling that Eve, Adalind, and little Kelly are connected. Adalind thinks she got pregnant when she sleep with Nick. How about she got pregnant when Juliette sleep with Nick as Adalind. It would better fit then, Adalind not knowing for all those months she was not pregnant.
