Angela and Ethan get separated from their group during a crowded Halloween subway rush filled with people in Ghostface costumes. Angela and Ethan end up on the same train but at opposite ends of the carriage, with tension between them as Angela already doesn’t trust him. During the ride, Angela is suddenly stabbed by a Ghostface who blends into the crowd and calmly walks away. As she collapses, Ethan notices her from across the carriage and desperately tries to push through the packed train to reach her, but the crowd and identical costumes make it difficult.
