Euphoria has been building up to Cassie and Nate's chaotic wedding - but did they actually get married? The Sunday, April 26, episode of the hit HBO series showed Cassie (Sydney Sweeney) and Nate's (Jacob Elordi) big day. While the guests were curious about the event, Nate was busy throwing up and Cassie was nearly pushed to the brink with pressure and stress. Despite delivering their vows without a hitch, things took a turn when a man Nate owed money to approached him during dinner. Some people overheard that Nate was very in debut, which Cassie was learning about for the first time.
