Grevane would need to kill him

"Make up your mind, Grevane!" I called. "If this goes any further, I'm going to do everything in my power to kill you. I can't beat you. We both know that. But you won't get the information out of me against my will. I'm not a pansy. I can push you hard enough to make you kill me."
"You would have me believe that you would simply commit suicide?" Grevane asked.
"To take you down with me?" I replied. "Oh, hell, yeah. Count on it."
