Fenrir dropped the Auror once he was well and truly into the undergrowth. As he did he heard a scream and he wriggled his way out of the bushes in time to see a woman standing in the clearing and a hex heading in his direction. He dodged the hex, feeling it whistle past his flank. It was strong and he eyed the woman with interest even as he growled.
He darted towards the woman, snapping his jaws in the other body's direction as he passed Natasha. He wanted that body hidden; he could distract the woman as she did that.
He dodged another hex as he closed in with the women and instead of trying to bite her, he just barrelled straight into her, sending her flying.
"Hey!"
Fenrir whirled around to see another Auror, a man this time, approaching them with his wand out. So here were the other Aurors that were meant to be on duty. He snarled at the man, not liking the odds, especially while Natasha was hiding the other body. He glanced at the woman and saw she was still lying winded on the ground. He turned back to the male Auror in time to duck out of the way of a hex. The spell creased his flank and he snarled at the sliver of pain that ran down his side.
He launched himself at the man, aiming for his wand hand. He caught the man's wrist in his jaws and dragged the man to the ground, chewing on his wrist until he severed his hand.
