When Sirius grinned at him, he smelled differently. He smiled like pack, he smelled like mate. Also, he smelled like fear and right now the wolf part of Remus wanted fear. He moved close to Sirius, close enough to touch him, but he didn't. Not here, not yet. If he touched Sirius out here, then he would need to shift entirely, and if anything altered the plan tonight it would be completely and utterly useless. A nod was made to the offhanded statement, because he couldn't focus on the words. His head lolled against his shoulder, and his eyes shifted to the moon who's call he was steadfastly refusing.
But couldn't for much longer.
A hand moved towards Sirius, and leathery fingertips touched the softness of his lover's skin. The pads of his fingers were more wolf then human, and it took a bit not to allow the claws to sink into the delightfully warm and slick skin below him. A growl vibrated through his chest, and he knew that several of his ribs were jerking themselves from position. But no sound escaped as he slipped away into the shadows, ready to pounce the bitch before she could dare to pull her wand and fire a spell at her son's head.
