Following the end of her photography class, Max Caulfield retreated to the girl's bathroom for a moment to herself. When she was feeling discouraged about her entry for the Everyday Heroes Contest, she tore the picture in two and discarded it, throwing it to the floor.
Moments after destroying her picture, she noticed a blue butterfly drift down from somewhere near the ceiling that flies into the corner. Curious, Max followed the butterfly into the corner stall at the far end of the bathroom.
Before taking the picture, Max notes that the butterfly doesn't look like any butterfly she'd seen before and thought the wings are glowing. After she takes a picture of the butterfly with her camera, Max believes the air is moving around her in the presence of the butterfly, which gives her the impression that it feels like a spirit.
After Max takes the picture and the butterfly departs, Nathan Prescott enters the girl's bathroom, followed by Chloe Price. When Chloe is shot, Max's rewind ability manifests and she undoes the events that transpired in the bathroom. When she goes to prevent her death, she retraces her steps in the bathroom. The blue butterfly appears a second time, and Max is able to prevent Chloe's death.
