Harry beats up Sanya

Sanya screamed and his weight shifted back.
I used that change of weight, set my legs, and drove him across the alleyway with the full power of my body and the strength of the Winter Knight. He hit the wall with a vicious impact. I felt it drive the air from his lungs, and I let out a shout of triumph as he bounced off, stunned for maybe all of a second.
I hit him, hard, three times in that second, driving my fist into the side of his neck, into the base of his jaw under the ear, and into his temple, wham, wham, wham.
The Sword fell out of his hand.
The Russian toppled. He hit the ground stunned, making gagging sounds.
“Self-righteous loudmouth,” I snarled down at him. “This is no concern of yours.”
The hate was calling me. I had no time for further distractions, as satisfying as they might have been.

But there was enough left of me to feel shame.
“I’m sorry,” I said. “Butters, I’m sorry.”
His face twisted with empathy, and his tears fell harder.
“Sanya,” I choked.
“Am all right,” I heard a groggy voice say from down the alley. “Bozhe moi, you fight dirty.” I felt a large hand come down on my shoulder. “Like a Russian.”
“Sanya’s here, too. He’ll be okay,” Butters said.
I teetered forward abruptly, unable to stay upright.
My friends caught me.
They held me.
