Ember Napper is a college student who just turned 21 years old and goes by the name Emma (her parents were “like, so embarrassing” and wanted her to have a “unique” name). Emma is a party girl at heart, and not a particularly bright one at that. She barely knows what the study is about and agrees to participate due to wanting to take a leave of absence from school anyway, where she is failing. Emma is friendly but loud and gets on the nerves of her fellow participants, especially Stephen. She is pretty much always bubbly, and one of her defining characteristics is her naiveté.

Preferred vocal range: Medium to high.
