De Groot

De Groot is a member of the Wesen Council who first appeared in.

De Groot was a member of the Wesen Council. The outbreak of Wesen violence in Portland, Oregon led to him being contacted by Rosalee Calvert and Sean Renard. He ordered that the offenders (Cole Pritchard and Krystal Fletcher) be executed.

After receiving a message from Rosalee about a possible Grausen case in Portland involving Daniel Keary, he ordered Alexander to kill Daniel. However Alexander failed to kill Daniel and when he returned he was surprised about Nick's decision towards Daniel. Nick sent Daniel's medical reports back with Alexander that revealed a parasite was the cause of the behavioral changes that people called Grausens. He told Alexander that nick was unlike any Grimm they had dealt with before and that they would have to watch him carefully.
