While you do feel for the faerie of which you have joined, you do have a pang of guilt...and a realization. Perhaps justice is best meted out. The fae here have power and can hold this human. Whatever punishment is meted out shall fit the crime. You know that humans think that fae do not exist...but to turn this one might prove beneficial.
You cast your dust to the chainsaw's body, running a contact along the surface, and tripping the cutoff switch. As the chainsaw coughs to a standstill. You fly up in the face of the human, and look upon the tree.
"If you were taking a few ancient trees to let the young ones grow in, perhaps I could convince my fellows to understand," you say, staring the human in the face. Ting sees your interaction and hears your words...she is intrigued. While your fellow fae are wary...this could be interesting.
"Why are you doing this?" You ask. "I didn't believe in my kind...until I became. I am giving you a fair chance. Answer truthfully."
