Madison

Madison sits in Kate's weight-loss support group, the friend who overshares before anyone's ready for it. She's funny in a self-deprecating way, quick to laugh at herself before anyone else can, and hungry for the kind of steady love she watches other people have. Underneath the jokes is someone bracing for rejection.

Caitlin Thompson plays Madison's neediness without making her pathetic — the oversharing lands as nervous honesty rather than a punchline, so the show can laugh with her instead of at her. It's a performance built on comic timing that keeps revealing tenderness underneath, which is why a character who could've stayed background becomes someone worth rooting for.
