Plot
Opening quote: "The enchantress was so hard-hearted that she banished the poor girl to a wilderness, where she had to live in a miserable, wretched state."
A couple hiking through the woods is captured by a drug dealer. As he prepares to kill them, he is lured away and killed by a creature, and the hikers escape. Nick (David Giuntoli) and Hank (Russell Hornsby) join other officers attending the scene. Nick discovers buckshot and a hair, and then spots a female Blutbad, who flees. Later, he asks Monroe (Silas Weir Mitchell) to help him. They enter the woods and Monroe tracks down the female Blutbad. She again runs, but they follow her to her treehouse, which they enter to find her passed out and ill with fever.
Bud (the man who previously fled from Nick after realizing he was a Grimm) tells two of his friends that he has seen a Grimm. They are skeptical but admit he is right when they pass Nick's house at night. When Nick arrives home, they flee. At the station, Sgt. Wu (Reggie Lee) tells Hank that DNA from the hair matches a previous case Hank was involved with: a missing girl named Holly Clark.
