Kieran Culkin, who plays Roman Roy on "Succession," helps us dissect the moments from the Season 3 finale that we still can't stop thinking about: the Roy sibling alliance, Gerri's betrayal, and the surprising ending. Plus, we discuss his upbringing as a child actor, why conjuring up his family's past doesn't actually help him in scenes and THAT Jeremy Strong New Yorker article. Fair warning: This conversation contains profanity.
