Lucifer turned at just the right moment to see her coming at him. He dodges, but barely. His head tilts and then he taps his chin. He heads into the shadows bleeding in perfectly. There he strips down the rest of the way and lets himself get angry. The sounds of bones cracking as he shifts echo. Though, he doesn't turn fully. He stops halfway. The result being werewolf like in appearance. Almost like a werewolf stepping out from the van helsing movie. His fur a rust color as he steps back out from the shadows. His canines poking out a bit from his muzzle. Ebony claws on the tips of his hands which had thick skin on the palms making them in between human and wolf. 
This makes it easier for him if he wanted to turn full wolf. He snarls at her, his full form being more primal resulting in his half form being just as primal. His ears flatten and then he runs at her his right hand aiming to hit her with his claws.
