Esther Hanes appears in The Strike in the Chord.
Esther Hanes is a member of the Gingersnaps, an all-girls a capella group at Lynwood University. The Gingersnaps were the main rivals of the Whippersnaps, an all-male group that was led by Scott Hill, who was murdered in the episode. Frustrated with the Whippersnaps getting all of the good gigs, Esther turned heel by infecting members of the boys' group with a strep-like infection, doing so by lacing her lip gloss with the bacteria and kissing certain members. After this was discovered, Esther was a suspect in Scott's murder, but she was eventually cleared.
