Grimm

According to Kelly Burkhardt, the Grimm trait is not strictly hereditary. Some offspring of Grimms have it and others don't. Girls also realize it earlier than boys.

Each episode opens with a quote from various fairytales or folk stories, which relate to the episode in some way.

There is a stained glass image of a wolf on Monroe's door; fitting as Monroe is a "blutbad" or "big bad wolf".
