That's not true and they both know it. The point of a cheap shot is because you don't want to play fair. He can't say that, however. Saying it would be an admission that he really did use her own arm against her. He knows she already knows, of course, but that's an entirely different thing than saying it was him.

As they circle one another, Darkleer can't help but quietly loathe how much more alive he feels when it's a fight that's happening. It happened with the Highblood as well, but at least he knows it was a little different then. A lot more twisted, a lot more complicated disgust and hatred and bloodlust in there. With Mindfang, it's almost... simple. The only thing that makes it any kind of confusing is the life debt, which does somewhat imply he shouldn't be raising a fist against her.

Then again, she wants this almost as much as he does, so it's alright.

When she lunges forward, he lunges right back even though he knows that it might mean a knife in his arm but perhaps that's the point. Perhaps he just want to see more blood spilled even if it's his own. Fortunately, or unfortunately, she pulls back before he can get his fist in her so he shifts his movement into something else. Falling to his own knee from his momentum, he slams his fist straight into the concrete. Stone is forced upwards, some of it even pelting into the surrounding area, and, most importantly, making the ground shake just a bit. That much force has his entire arm ache. Even for him, punching into stone isn't a pleasant experience, but he'll suffer through it.

He'll suffer through it so long as it gives him a chance to catch her offguard, a chance to rush her and try and slam her to the ground next.
