Lucy

Lucy drifts through the edges of the story in The Trip, glimpsed rather than fully drawn — a presence in someone else's road trip rather than its center. She has her own poise and her own agenda, even if the show is more interested in the men bickering over dinner than in her.

Rosie Fellner brings an easy naturalism to a role built from small moments rather than big speeches, holding her own in scenes engineered around improvisation and one-upmanship. She works because she never competes for the joke — she just makes the world around the comedy feel like a real one.
