Victoria 'Tori' Spring

Tori is Charlie's older sister, a sixth-former who moves through school with a flat, unbothered expression and a tongue quick enough to shut down anyone who bothers him. She seems detached from everything around her, uninterested in friends or drama, but she is always watching, and always ready to step in for Charlie.

Jenny Walser plays deadpan without making it a joke — Tori's dryness reads as armor rather than personality quirk, and the show trusts silence to do the work. She's the rare sibling character who feels like an actual sister: irritated, loyal, and paying far closer attention than she lets on.
