Supporting characters
First generation
Effy Stonem (Kaya Scodelario): Effy is Tony's sister, who appears sporadically in the first two series, not speaking until her first central episode right before passing out at a party. She also contributes to sorting out the relationship problems between Tony, Michelle, Sid and Cassie. She becomes the lead character in the next generation. Posh Kenneth (Daniel Kaluuya): Posh Kenneth hangs around with members of the Skins gang on occasion. One of his chief characteristics is his code-switching between British English sociolects. In the series 1 finale, he displays a romantic interest in Jal. In the first episode of the second season he is seen rapping at a party that the gang attends. On the official website, he states that he wishes to become a psychiatrist or a politician, and that his heroes are Sigmund Freud and Trevor McDonald. Abigail Stock (Georgina Moffat): Abigail is a posh choir girl and stereotypical rah who is friendly with Tony, and with whom he occasionally cheats on Michelle. Her mother works as a doctor at the rehabilitation centre which Cassie frequently visited. She is the sister of Josh. After Tony's accident at the end of Series 1, Abigail pretends to have been his girlfriend before the accident, and tries to continue this when she sees him. After Sid reveals to Tony that he loved Michelle and not Abigail before the accident, the couple part ways. Josh Stock (Ben Lloyd-Hughes): Josh is Michelle's boyfriend in her central episode. He candidly reveals that he believes his mother (Cassie's psychiatrist) is "psychotic" and that she psychoanalyzes and medicates her children, and claims that he is a "different person" off the drugs. Tony sends Michelle sensitive pictures of Abi from Josh's phone, making her believe he is crazy and dumping him. Josh reappears in "Effy," when he, along with his friend, Spencer give Effy some drugs, and then try and force Tony to have sex with his unconscious sister. After much begging and pleading, Josh allows Tony to walk away with Effy, declaring that "here endeth the lesson." It is later revealed that the drugs Josh gave Effy were actually clean Pharmaceuticals, which Josh most likely stole from his mother's clinic. Pandora Moon (Lisa Backwell): Pandora appeared in Series 2 when becoming a new student at Effy's school. Effy soon befriends her despite their noticeable differences. Pandora tags along with Effy to sort out the problems between Sid, Cassie, Tony and Michelle. Pandora soon becomes a main character in Series 3 and 4. Mad Twatter (real name Madison Twatter) (Stephen Walters): Mad Twatter first appeared in Episode 1 of Series 1, when Sid buys marijuana off of him. However, after losing three ounces of the drug to Sid (who doesn't pay), he comes after and threatens Sid. After finally catching up with Sid, along with Jal Fazer, Mad Twatter destroys Jal's priceless clarinet, and beats up her brothers when they go after him. In response, Jal's father and his bodyguards corner him under a bridge and drive him away. His whereabouts are never revealed. Water Bottle Girl (Danielle Jadelyn): Water Bottle Girl was a girl that went to the same rehabilitation centre as Cassie, and appeared in two episodes of the first series. She was first seen drinking a large bottle of water to make up the weight so she could be discharged from the clinic, but ended up running to the toilet. The two become friends after sneaking out and getting a taxi into town, where she buys chips from the takeaway. Alan the Taxi Driver (Alan George): Alan is the friendly taxi driver that takes Cassie to the rehabilitation centre, and seems to be the only one that understands her. Cassie seems to think of him as a father figure. Simon (James Buckley): Simon is Cassie's boyfriend in the Series 1 episode, "Michelle". They both are patients of the rehabilitation centre. James (Sean Verey): James is a gay cyclist, and Maxxie's love interest since Episode 8 of Series 2. James and Maxxie later become an official couple, and move to London together in the series two finale. Jake (Angus Harrison): Effy's friend from the Series 2 episode, "Effy". Scarlett (Sia Berkeley): Michelle's step-sister. Although Michelle thinks of her as a "bitch", her friends (especially Chris) take an instant liking to her and she proves to be useful several times during the trip, providing them with travel and encouraging Michelle to chase after Sid when he is depressed, to which Michelle has a change of heart towards her.
