The emotional heart of Netflix's must-watch series The Diplomat is the fiery, complicated relationship between U.S. Ambassador Kate Wyler (Keri Russell) and her morally dubious husband Hal (Rufus Sewell). By the end of its third installment, which showed both the couple's beginning and their brief separation (in the wake of Hal's new role as Vice President), Kate returns to her husband and recommits herself as his partner-in-crime. But that's before a major betrayal involving President Grace Penn (Allison Janney) changes everything.
With all episodes of season 3 released in fall 2025, viewers may leave their binges wondering whether Kate and Hal's relationship will ever be the same (and, you know, whether World War III is on the horizon). Below, we're keeping track of everything we know about The Diplomat's future so far. (If you're looking for a full breakdown of The Diplomat season 3's ending, we've got you covered.)
