After Jules reveals her online love connection wants to meet up with her, Rue expresses concerns at her meeting someone alone, late at night. It leads into an argument that is subsequently resolved when Rue goes to Jules's house to apologise. It's another vulnerable look at Rue, but it's also a glimpse at how deeply she cares for Jules. She's visibly nervous, fidgeting as she attempts to convey her feelings for the other girl. Rue admits that the idea of Jules being angry at her "hurts my heart too much," and she pleads with Jules not to be mad at her.
While on the surface it's a sweet scene that leads to the characters' first kiss, it's truly a scene that shows how intensely invested Rue has become in her relationship with Jules. Zendaya presents Rue as a scared girl not wanting to lose her friend but also demonstrates how Rue has gained a new addiction she's desperate to keep in her life: Jules. Her pleading to Jules is a softer lead-in for the next scene, which shows a darker side of Rue's inclinations.
