The hungry figure at the end of the hall at least starts out as humanoid. But his eyes are like fire and he has too many teeth, and nothing about the way he watches the other man seems truly human.

Then Huaisang flees and the game is on. The demon stops pretending altogether.

Two steps down the hallway, some decision is made in his head that running down the corridor on two legs is going to take far too long. He's impatient to have something trapped and squirming beneath him now. So, the sound of human footfalls quickly give way to the sound of four sets of clicking claws and heavy paws pounding against the fancy tile, and his prey has two seconds before a whole lot of muscle and fur tackles into him from behind.
