Of all people to launch an attack on close proximity of, Cain was not the smartest choice. Although the man clearly had no idea who was around the corner any more than the former-assassin did, it didn't matter. Cain tapped the hidden blade he had drawn lightning fast against the back of the assailant's neck three times. He had moved with incredible speed, doing a three-sixty on his heels and found a position forty-five degrees behind and to the left of the man. His blade was two inches wide and ten inches long and lay flat side against the side of the attacker's neck. 

With a calm, collected tone that only added an eerie feel to his words, Cain said to the man, "This blade is sharper than a surgeon's knife. It is placed directly over your bracheoplexis origin. One small movement of my wrist, or one wrong move on your part will kill you. You will put Amuné down and I will retract my blade." His voice, although deep and gritty from a previous injury, was was colder than the obsidian steel that lay against this man's neck. 

Had Amuné not expressed familiarity with him, Cain would have ended his life then and there.[@shylarah]
