The Immortal S01 E11 Forest for the Trees

The trail of demons takes Rafael, Goodwin and Sara to the northwest forests. Three nature spirits, sisters, share a crystal among themselves. However, one has turned to the side of Hell, become a corporate logging executive and is using foresting to try to draw out her other two sisters and gain their power. Meanwhile, the other two sisters seek to make Sara their third, while a wood nymph tries to seduce Goodwin. Ultimately Raphael recovers the crystals and defeats the evil sister.
