He smiled.
It couldn't be helped, not with this wicked pleasure slithering through him. She dangled in front of him, and he couldn't resist reaching out to hook at her with his claws.

Taking a step back and drawing an even breath, his eyes brightened as he focused every bit of his attention on her-- the only readying he cared to do in preparation for this little spar.

So very rarely did he ever lower himself to become engaged in a physical struggle of any kind. Opponents were never allowed close enough to even try. It wasn't that he wasn't capable of it; his upbringing demanded nothing less. It was just so against his way of thinking and dealing with trials, he simply harbored an intense distaste for it. Weapons were what they used.

He used no weapon, but simply allowing her to come at him with one went against his instincts. He was making an exception for her. There may have even been something about this perversion of his personal morals that added to his interest in it. The same sick enjoyment he derived from humoring Integra even in conversation.
