intercepts stun gun

I stopped. I closed my eyes. I took a deep breath, and tried to get a handle on my anger. It wouldn't profit me anything to lose control.
That was when she went for the stunner.
I heard her move, opened my eyes in time to see her snatch a black-plastic case the size of a cellular phone from the piano and lunge toward me. Her face was pale, frightened. Blue lightning danced between the two tines of the stunner as she shoved it at my stomach.
I swept my staff, upright, from right to left, and the buzzing device went past me, along with her lunge, striking the doorframe behind me. I slipped past her, into the living room, turning to face her as she recovered and turned around.
"I won't let you hurt them," she snarled. "Not you, not anyone. I'll kill you before I let you touch them, wizard. " And then she was coming at me again, fury replacing the terror in her eyes, a grim determination to succeed that made me think of Murphy for a second. For the first time, she was looking me in the face. For the first time she forgot to keep her eyes averted from mine, and in that second, I saw inside of her.
Things seemed to slow down for a moment. I had time to see the color of her eyes, the structure of her face. To recognize where I had seen them before, why she had looked familiar to me. I had time to see, behind her eyes, the fear and the love that motivated every move she made, every step she took. I saw what had moved her to come to me, why she was afraid. I saw her grief, and I saw her pain.
And the pieces all fell into place. Knowing the emotions that drove her, the terrible love that she was showing even now, it all seemed perfectly obvious, and I felt stupid for not figuring it out days ago.
"Stop," I said, or tried to say, before she thrust the stunner at my chest. I dropped staff and rod alike in a clatter of falling wood, and caught her wrist in both of my hands. She pushed the stunner up at my face, and I let her do it.
