Plot
Many months ago, Geppetto tries entering the Sacred Grove of Haven, but fails. After insulting what Bigby and Snow were doing earlier in the grove, Geppetto sends Sir Woldred, a tiny wooden knight, to reach to the grove. After killing several animals who were huge to him, he arrives at the grove, but is starting to become a tree himself. Gepetto finds Woldred infected, and becoming a grove tree, so Gepetto takes him for evil purposes. Geppetto is taken to the Farm where he plants Woldred so he can grow into a strong tree for him.
