Who Plays Key Characters Like Vanessa, Claire, Gladys, Apollo, and Mona?
Vanessa — Constance Marie
Constance Marie plays Vanessa Cascade in season 2. She is Julie’s estranged mother and a professional con artist. The role was listed in the Wikipedia cast table.
Claire — Not Confirmed
A character named “Claire” does not appear in the official season 2 cast lists from the available sources. The closest match is Michaela Conlin as Andrea Yi, according to Rotten Tomatoes. Until a reliable source confirms a character named Claire, the actor remains unverified.

Apollo — Not Found
Despite checking Wikipedia, Rotten Tomatoes, and TV Guide, no character named Apollo appears in either season. It is possible the name was misremembered or refers to an uncredited extra, but no evidence has been found.
Mona — Mary Steenburgen
Mary Steenburgen plays Mona Margadoff in season 2. She is Charles’ love interest and a new resident of Wheeler College. The role is well‑documented across all three sources.
