Marie Kessler

Marie is Nick Burkhardt's aunt, but served as his mother after his parent were killed. She arrived at the home Nick shares with Juliette Silverton without warning driving a sport utility vehicle towing a trailer Nick never knew she owned. She told Nick they needed to talk.

Marie told Nick that he was the last of the Grimms, descended from the Brothers Grimm. Shortly thereafter, she was attacked by Hulda, wielding a scythe; Nick killed Hulda.

At the hospital Adalind Engel attempted to kill Marie, but Nick intervened.
