Who Is Agnes in 'The Summer I Turned Pretty' Season 3?

Agnes joins the story as Conrad Fisher’s close friend from Stanford and a fellow pre-med student. Both are doing a competitive summer clinic residency together, where Agnes’s intelligence and emotional maturity make her an immediate standout among the new faces introduced this season.

While book fans might recognize the name from Jenny Han’s original trilogy, the show’s version of Agnes is reimagined. In the TV adaptation, her connection with Conrad is platonic: she’s a supportive peer, often challenging him to open up emotionally, while making it clear that there are no romantic intentions between them.

This presents Agnes as a genuinely positive presence in Conrad’s life, and she quickly becomes a favorite among fans for her thoughtful conversations and friendly nature.
