Season 1[]

Season 2[]

In Episode 6 "Gathering", when Eric tries inviting people to Otis's "small gathering", Ruby is initially averse to the invitation. However, upon realizing that Rahim would attend, Ruby quickly changes her mind. During the midst of the party, she is seen dancing inside the house. A drunken Otis approaches and gets down with her. It is revealed in Episode 7 "The Girl-Fast Club", the two had consensual sex, but whether a contraceptive was used is in question. The morning after the party, Otis attends school and is in a chemistry class. It is at this time he hears Ruby outside, throwing pebbles at the window to draw his attention. Outside, Ruby discloses that she's actually "96.5" percent certain that a condom was used during their sex, which departs from her initial "99" percent certainty. During this episode when Ruby was buying the morning after pill it is revealed that her father has been suffering from multiple sclerosis and that was the reason she had a one-night stand with Otis.

Season 3[]

In the opening of season 3 it is revealed she has been having casual sex with Otis throughout the school summer holiday, which started at a fancy dress party after season 2, Otis was dressed as macaroni cheese while Ruby was dressed as Christina Aguilera. While Ruby initially threatens Otis to keep their affair private, he told Eric which lead to Lily telling the whole school about their casual sex. In spite of this, Otis became more involved with Ruby and eventually asked if he could be her boyfriend to which she said yes. While initially mean to Otis, bossing him around and trying to change his behaviours and fashion sense, Ruby becomes kinder to him. Ruby dated with Otis for some time and even took him to her house which not even Anwar or Olivia had been to and introducing Otis to her dad. It is revealed that Ruby comes from a humble household which she is insecure about it and is why she never invited anyone over. Later that night Ruby calls Otis and tells him she loves him to which Otis replies, "That's nice." Ruby becomes very upset with Otis as she has never told anyone that she loves them and the two break up.

During the school trip to France, Ruby is still upset with Otis while Olivia and Anwar remain hostile towards him but she tells him she doesn't hate him. The trip finally culminates with Otis kissing Maeve while they were unintentionally left at a service station for some hours. As the coach returns and approaches Otis and Maeve kissing, Ruby sees the two of them together kissing and appears heartbroken once again.


Love Interests and Sexual partners[]

Tom Baker[]

Ruby dated Tom Baker aka "Warhammer Tom" for a week before dumping him on the pretext that he smelled like crisps but more concretely, she didn't enjoy his company. Frustrated, he will later send a photo of her to Kyle who didn't believe that Tom had sex with Ruby.

Otis Milburn[]

Otis and Ruby

During season 1, Otis and Ruby never interact except during episode 5 during which he and Maeve will help her identify the person who sent the whole school a compromising picture of herself.

Their interactions in season 2 are once again almost non-existent, but their relationship takes a most unexpected turn when, following episode 6 (and a party a little too alcoholic), Otis wakes up in his bed with a hangover and Ruby by his side. She casually confirms to him that they had intercourse last night but that she cannot find the condom, which worries Otis greatly. She will later admit that she is not sure that their intercourse have been protected. The two then go to a pharmacy to get a morning after pill. If Ruby is reluctant at first to enter it, Otis' arguments will eventually convince her. During the questionnaire to obtain the pill, Otis learns from Ruby's own mouth that her father has been suffering for one year from "multiple sclerosis" (MS), a disease affecting the central nervous system and which can lead to permanent physical incapacity in the patient and in the worst case, his death.

After getting the pill, Otis will worry about whether Ruby was consenting at the time of their intercourse, to which she will answer yes, justifying this by her habit of sleeping with "nerdy boys" when she is sad, which gives her for a short time the feeling of being passionately loved. Otis reveals to her that this was his very first sexual intercourse and asks her about the level of his performance. Surprised, she replies that he was not great but not terrible either.

Otis asks if her father's illness is causing her sadness. She answers him yes but immediately diverts the subject of the conversation by accusing a lack of symmetry in her eyebrows after epilating them. Playing the game, Otis replies that he finds them very even. Ruby smiles at him and thanks him for accompanying her, adding that most boys are not as considerate as he is. Their arc for this season ends with Otis driving Ruby back on his bike.

In season 3 they end up having casual sex in cars and the abandoned toilets which then evolved into a relationship where Otis ended up brutally dumping her.


Her father[]

In episode 2.7, we learn from Ruby's own mouth that her father has been suffering for one year from "multiple sclerosis" (MS), a disease affecting the central nervous system and which can lead to permanent physical incapacity in the patient and in the worst case, his death. He already had to quit his job.

Her mother[]

The deterioration of her husband's health causes her a lot of stress, according to Ruby.

Her grandmother †[]

The loss of her grandmother seems to have affected Ruby, in episode 1.5, she uses this tragedy as an argument for dating Tom Baker aka "Tom Warhammer" for a week which, as we learn during the episode 2.7, would correspond to her habit of sleeping with "nerdy boys" when she is sad.


Olivia Hanan[]

One of Ruby's friends, Ruby is very mean to Olivia causing her to post pictures of her vagina.


One of Ruby's friends


Maeve Wiley[]

Ruby is always on the front line when it comes to mocking Maeve or calling her by her cruel nickname "Cock Biter" even after she and Otis have helped her solving the case of her leaked vagina pics without expecting any compensation, help for which Ruby of course never thanked them.

During Episode 2.1, Maeve, irritated by Ruby's behaviour, revealed to the whole school via the loudspeakers that she was one of her many clients for essay plagiarism. Although the animosity between them has so far never been more than a deep mutual contempt, the revelation of Otis having his first sexual intercourse with Ruby may have changed the situation as it seems to have particularly pissed off Maeve.

Aimee Gibbs[]

A former friend of Ruby until she chooses to be with Maeve over the Untouchables and renounces herself from the clique, making herself the target of their mockeries.


She can be rather rude to other students, including her own friends, she will eventually pay the price when her friend Olivia, annoyed by her incessant mockery, decides to take revenge on her by sharing a compromising selfie from Ruby's own cell phone. She likes good parties, gossips and trendy style. She’s a vegan. She likes to rule and impose her views on others. Treats everyone in advance.

However, during episode 2.7, Ruby, despite her naughty, arrogant and self-confident girl face, revealed herself to be a much more complex character than appearances suggest, with a tragic dimension. She is reluctant to show what she really feels and is in perpetual control, the most glaring evidence being her reaction when Otis asked her about her father's multiple sclerosis, although her body language briefly betrays her concern, she refuses to reveal her feelings further and immediately try to divert the conversation by using derision.

On the other hand, Ruby isn't happy in love, this is highlighted when she says to Otis "when I'm sad, I make out with nerdy boys... because they think they're in love with me, which feels amazing, until they get clingy and want to show me all their things. " She doesn't find what she's looking for in her partners and probably doesn't have a very clear idea of ​​it, yet she desires what so many other people desire : to love and to be loved with passion.

  • She is considered by many to be the prettiest girl in school.
  • She’s always sticking with her gang.
  • In high school, she was the first to get a car amongst her friends. (Episode 1: "Sex Kid")
  • After Maeve, she is the second female character to have shared a moment of closeness with Otis before threatening him with reprisals if he told anyone about it. (Episode 2.7: "The Girl-fast Club")
  • She tells Otis she likes making out with nerdy boys when she's sad. This can be tied to how she also used to have a thing with Warhammer Tom, who is seen as a huge nerd.
  • She tells Otis not to stand next to him (in Season 3, episode 2) when he is eating because she has Misophonia (which Olivia slightly incorrectly explains means she - Ruby- has a phobia of the sound of people chewing). Misophonia is a disorder of decreased tolerance to specific sounds or their associated stimuli that has been characterized using different language and methodologies. Reactions to trigger sounds range from anger and annoyance to activating a fight-or-flight response. The condition is sometimes called selective sound sensitivity syndrome. Common triggers include oral sounds (e.g., loud breathing, chewing, swallowing), clicking sounds (e.g., keyboard tapping, finger tapping, windshield wipers), and sounds associated with movement (e.g., fidgeting). Oftentimes, hated sounds are repetitive in nature. One study found that around 80% of the sounds were related to the mouth (e.g., eating, slurping, chewing or popping gum, whispering, whistling) and around 60% were repetitive.
