After kissing Jules, Rue is a frenzied mess, and we all know what she turns to when she needs solace from her emotions. But when she meets up with everyone's favourite dealer, Fezco, he refuses to sell anything to her. This sparks a rage in Rue that viewers haven't seen before, and it's a stark reminder that, as sweet and fragile as Rue is, she's still a drug addict — they don't tend to take obstruction from drugs very well.
Zendaya pulls off Rue's combination of fury and desperation so well, it's hard to watch the scene through. The teen goes from cordial to outraged, from begging to demanding, to just shrieking, ordering Fez to "open the door." It's an absolutely chilling scene, and we're forced to remember there's nothing cute or glamorous about Rue's addiction.
