Willow darts after him, slipping a bit on the floor as she rounds the corner into the open stall. At first, she positions herself directly in front of Stiles, crouched low in case it comes to a fight, then she hears the fast, heavy breathing. She turns around and tucks in close to his side instead, still tense as the heavy footsteps come closer and begin to slow as though something may need investigating, but clearly trying to help offer comfort too.
