When Suzy returns to the school, she finds that everyone has left to attend the Bolshoi Ballet. After being attacked by a bat and recalling a conversation with Sarah about footsteps, she follows the sound of them carefully, leading her to Madame Blanc's office. Remembering that Pat uttered the words "secret" and "iris" the night that she was killed, Suzy discovers a hidden door that opens by turning a blue iris on a mural in Blanc's office. Suzy enters the corridor and finds the academy's instructors, led by Madame Blanc, plotting her demise. Albert alerts Pavlos to Suzy's presence. Suzy hides in an alcove, where she finds Sarah's disfigured corpse.
