This is where performs its first magic trick. It weaponizes the viewers' expectations. We expect the teacher to scream, to cry, to call the police. She does none of those things. She reveals that she has injected the milk cartons of the two murderers with HIV-positive blood taken from her recently deceased husband (a fact she later reveals as a lie—a psychological trap).
The film forces the viewer to confront the uncomfortable reality that evil isn't always a villain twirling a mustache—sometimes it is a child wanting to be seen by his mother, or a teacher wanting to avenge her daughter. The ending is one of the most crushing in cinema history, leaving the audience with a final line that echoes in the mind long after the credits roll. Confessions.2010
