What to Expect in Season 4
Season 3’s finale suggests The Diplomat will weather more complications than ever, with showrunner Debora Cahn noting that fans “should be worried” about who takes power and their potential misuse of it.
Season 3 ended with Kate discovering critical information about Hal while President Penn authorized seizing a Russian nuclear weapon in British waters—shattering trust in both Kate’s marriage and the US-UK alliance.
Creator Cahn expressed excitement about Season 4, saying “We get to the end of a season and I always think, ‘Well, there’s no way that we can do this again.’ And then we dig back into it, and it’s like, ‘Oh my God, we have to keep going.'”
