S3, E6: Naomi (Lily Loveless) thinks she has the world worked out, and puts people in their appropriate boxes. There's her hippy mum (Olivia Colman); the adoration from Emily (Kathryn Prescott); Cook's (Jack O'Connell) insulting misogyny; and her politics teacher, Kieran's (Ardal O'Hanlon), flattery. She thinks she has them all sussed, and that it's only her who can see the truth. However, the upcoming student elections leave her at a loss, and her insecurities get the better of her. The trust and confidence inspired by a friend encourages her to stand up to her arch rival, the antithesis of everything she stands for, as her and Cook go head to head; but Naomi learns that nothing is black and white anymore.
