Climbing the jacket with Galevin, Tozoku makes it to the top of the teacher's desk.  Minutes later, he sees a red wolf, the same one he saw earlier that day.  Galevin tells the cat to hide, so they don't get seen.  Tozoku knew that wolves had strong noses, and they wouldn't be hidden for long.  The wolf was calling for Mrs. Ard, who was probably the teacher.
