The only clue I had a problem with was "Didn’t I tell you to bring your other half? No matter, though it’s no fun to hunt the fray alone" - That really made me think of either a twin or a companion. It was a bit too vague for mate, and even so a lot of characters have mates. "Bring the other half of your heart" would have worked well, since it refers to love and both he and Cherie have heart markings.
That and the stealth in general gave a sense of someone particularly vicious or violent that would hunt. Regardless, your clues were very solid and this was a clever stealth. Good steal, Angel.
