Chadwick's Temple

Come on Arty, let me teach you a few moves! You'll thank me some day!
I'm a doctor. Who am I going to fight?
Let me just teach you two or three things about blocking knives. Just in case you ever get into a spot of trouble.

If Arty still was able to see his brother, he'd apologize to him. Arty's build is more lithe than bulky, but he does have some muscle behind him. His arm opposite the knife hand snakes out and grabs her by the wrist, holding it fast and likely keeping it from his gut. With his other he grabs an arrow from his quiver and tries to jab the possessed girl in the neck with its head. The arrow (which he primed when he drew it) delivers an electric shock like a taser!
That was Arty's only stun-arrow. He's so glad his father left him with a few of his goods when the Nexus took him in.
