Appearance
Quill's real appearance could make humans scream. (PROSE: Joyride) A part of the Lan Kin pretending to be her sister Orla'ath said she wore her human appearance well. (TV: Nightvisiting)

Personality
Miss Quill was a blunt and sharp tongued teacher, and a strong, stern woman. In class, she was blunt and condescending towards her students. She broke Charlie's phone when he attempted to internet search pop culture references, and mocked April when she tried to intervene. (TV: For Tonight We Might Die) She believed that nobody liked her, or cared about the things she faced. (TV: The Coach with the Dragon Tattoo) She is also very bitter towards Charlie, likening her servitude to him as slavery due to the harsh conditions she must face. Her bitterness will extend to others if she chooses, such as her first class. (TV: For Tonight We Might Die) She is also willing to put somebody's life in danger, such as Charlie, to suit a bigger purpose, or so she can actively fight (TV: For Tonight We Might Die, TV: The Coach with the Dragon Tattoo) Very analytical, she has shown annoyance when people do not spot what she does or when she has to explain what it means. (TV: The Coach with the Dragon Tattoo)

History
She was a freedom fighter on her home world Rhodia. (TV: For Tonight We Might Die) She said she once led an army. (TV: Nightvisiting)

When the Rhodians defeated her species, Miss Quill was enslaved by the Rhodian prince Charlie before the Shadow Kin arrived. She and Charlie were rescued from there by the Twelfth Doctor, in the midst of the war. She was brought to Coal Hill Academy in 2016, together with Charlie, where she posed as a teacher from Sheffield.

Miss Quill continued to live with Charlie who confronted her about Kevin's supposed disappearance. At night in the school she hid with a student named Kevin from a Shadow Kin that materialised. Unable to use a weapon on the creature due to the terms of her enslavement to Charlie, she ordered Kevin to do it. The weapon killed both him and the Shadow Kin. When more Shadow Kin appeared, she next ordered April to shoot the Kin but the latter was prevented from doing so by Charlie. Due to this, the Kin was not destroyed and Miss Quill used her scanner to discover that the Kin and April shared a heart. She assisted in making Prom decorations- though they were very pessimistic. On the night of the Prom, she gave her gun to Charlie and witnessed the legion of Kin arrive at the school but was unable to weild a weapon. She prepared to go down fighting before the 12th Doctor showed up and dispelled the Kin. (TV: For Tonight We Might Die)

A week later, a robot was sent to spy on Miss Quill disguised as an inspector from Ofsted. Quill quickly began to suspect that he wasn't human due to his inability to speak and his fast reflexes. She was annoyed that Charlie and his friends were more focused on a series of murders committed by a skin-peeling dragon than the inspector, so she decided to take matters into her own hands and investigate the inspector by herself.

Quill approached the inspector in the school at night and asked what he wanted. He wrote in his notepad that he wanted her, leading to her assuming he was interested in her sexually. She quickly pushed him against a wall and began kissing him. They were interrupted by a skin-peeling dragon and chased into a classroom. Not wanting to die, Quill pushed the inspector towards the dragon. Instead of being skinned, the inspector broke apart, revealing he was a robot. Shortly afterwards, the dragon left Coal Hill through the space-time rip. Quill then gathered the pieces of the inspector and analysed them, learning it was created by the Governors.
