During the events of Trick 'r Treat (2007) played by Leslie Bibb
Emma goes with Henry to the Halloween parade in Warren Valley dressed as a robot. As they are walking through downtown, Emma and Laurie bump shoulders together and Allie asks Emma for help. Emma leaves Allie, when Henry tells her Allie is drunk. Emma and Henry return home and Emma complains that Henry doesn't respect her. Despite Henry's warning, Emma blows out the candle to their jack-o-lantern and starts to remove their Halloween decorations. While taking down the decorations she sees Teenager, who she thinks is staring at her, but is just waiting for his ride. Emma is killed by Sam, who slashes her throat with a jagged lollipop and places her head on a wooden support.
