Gemma was a teacher at St. Theobald School. She developed a crush on a fellow math teacher, Niko Polastri, and resented his wife, Eve. Niko briefly stayed in Gemma's apartment after he left Eve.
Gemma attends a teachers' conference at the school, where she meets Eve for the first time, covertly flirting with Niko. She later shares cigarette with Villanelle in disguise, who advises her to undermine Eve in front of Niko in order to win him over.
Gemma's standout features are being passive aggressive and a bit dim-witted. Her long-standing jealousy of Eve's relationship with Niko leaves her vulnerable to Villanelle's manipulation.
Her parents were told she committed suicide.
