Spoiler alert! This story reveals the results of The Ultimatum Season 4, including the finale and reunion, which can now be streamed with a Netflix subscription.The Ultimatum: Marry or Move On Season 4 has wrapped, and as far as partner-swapping Netflix reality shows go, I found it quite underwhelming. Nobody fully bought into the trial marriage portion of the experience, and several cast members were problematic or obnoxious to the point that they were hard to root for. The season finale hit the 2026 TV schedule this week and was severely lacking drama with its way-too-predictable ending. Thankfully, Nick Lachey came through in the reunion with a move that saved it for me.(Image credit: Netflix)It Was Obvious That Every Season 4 Couple Would Get EngagedWith no cast member catching feelings for anyone else on The Ultimatum Season 4, it was pretty clear that all four original couples were going to get engaged at the end — regardless of whether or not that was a healthy choice. Blake Robertson proposed to Hayley Hendrich despite their continued fights throughout their trial marriage, as did Killian Grondin and Ashley Wilson, who never stopped talking during their weeks apart.It was extra discouraging to watch, because days before the finale aired, news broke that Blake Robertson was arrested in October 2025, per TMZ, on accusations of assaulting Hayley Hendrich. She chose not to press charges, and the case was dismissed with all records expunged. Page Six reports that Robertson has denied all abuse allegations and said his actions were in “self-defense,” but either way, an incident like that zaps all the fun out of your TV love story.Add to that a complete lack of suspense regarding the fates of the other three couples involved, and I found myself struggling to keep my focus on the screen.(Image credit: Netflix)Nick Lachey Singing ‘I Do (Cherish You)’ Was The Highlight Of The Ultimatum’s Finale And ReunionJust like The Ultimatum Season 4 finale was predictable, I wasn’t surprised that only two couples remained together when the reunion was filmed a year later — Casey Douglass and David Atkinson were still betrothed, as were Monica Payne and Luke Wesselhoff. However, I can’t say that I expected Casey to ask Nick Lachey to officiate a legal ceremony for them, right then and there. The Ultimatum’s host is ordained to perform marriages in California, and Casey and David needed to be legally married in the United States before their Italian nuptials in September. It wasn’t just that Nick Lachey performed the ceremony — a simple but sweet vow exchange — that roped me back into the show. It struck me just how cool it would be to have the singer of 98 Degrees officiate your wedding. Like, this is the dude who sang “I Do (Cherish You)” in the glorious TRL days when I was a lovesick high-schooler. Was this man really going to perform an actual wedding and not sing the iconic song?I was aghast as the couple officially became husband and wife without Nick Lachey’s musical accompaniment … but then there was the bouquet toss. As Casey Douglass prepared to designate the next bride-to-be, the 98 Degrees frontman broke into an a capella version of “I Do (Cherish You),” certainly making Casey and David’s big day complete. It was a really cute moment, because honestly, how many people can say they were serenaded with that song on their wedding day — by Nick Lachey himself? I’m not sure it made up for all of my issues with the dating show, but it did leave me on quite the unexpected high. The Ultimatum Season 4 is available to stream now on Netflix.
