I am about to knock the fool unconscious when Lucien gets his second wind and comes after me. Good, now he's agitated and not thinking rationally at all.

His body slams into mine, and we go down. As we do, I reach my boot, and when we land, I let gravity take it's terrible course. As we land, Lucien lands right on my knife, and I feel the give of flesh, the warm ooze of blood on my hand.

Lucien winces at the pain, and his face registers that, and a bit of surprise. Meet his eyes again, and give him a smile.

"Believe me when I tell you this is not personal, Doctor Constantine." I whisper, then I roll him, pull the dagger from his chest, and then bury it in his gut, twisting it hard. Should only take him minutes to bleed out, if that. But just to be sure, I pull the blade out and raise my arm again, aiming for his neck this time.
