When you watch Grimm Season 6 Episode 5 online, Team Grimm investigates an odd murder in a local park where a man was left completely naked. Rather than suspect ordinary sadistic sexual crime, they immediately believe that it's got to be Wesen-related. Their suspicions quickly prove correct as they unearth another body, this one having been underground for a number of years and fed upon by the Wesen in question. After some investigation, they discover that the Wesen only emerges from underground every seven years, and only for one night, after which it will return with a new victim to sustain it for the next seven years. Meanwhile, Renard is increasingly tormented in creative ways by a cheerfully vindictive ghostly Meisner. And Eve's own condition down in the tunnel deteriorates after she is compelled to draw strange symbols into the walls -- symbols that Diana has also been drawing. What is the connection, and what do the symbols mean? How far will ghostly Meisner go to haunt Renard, and what will Renard do to get rid of Meisner? Will Team Grimm be able to stop this monstrous Wesen before he chooses and kills a new victim to serve as his meal? Find out when you watch Grimm Season 6 Episode 5 online!
