Nate Ruggles and Lauren Pounds came on the show due to one main disagreement — Nate wanted multiple children and Lauren did not want any.
However, in episode three, Nate followed in Hunter's footsteps and proposed to his partner Lauren before they got to the trial marriage stage.
The couple's costars criticized the proposal at the time since the pair had not solved their issue surrounding children.
In the reunion episode, Lauren said that they had worked on their relationship off-camera and agreed on one child.
The pair did eventually get married in October 2022 and are still together.
Since leaving the process both Lauren and Nate have been critical of the way the show presented their relationship.
Lauren wrote in the caption of an Instagram post last year: "You know that you've found the one when you walk through a dumpster fire together and come out stronger than before. The fake/edited version of us that was shown on The Ultimatum won't sit well with everyone, and we're slowly learning to be okay with that."
"We left early because we quickly realized how toxic the experience was, so we got punished for going against the grain. Lesson learned! So, if anyone has a problem with us doing what was best for our relationship, please project your misery elsewhere, not on our pages," she added.
Lauren added in the caption that Nate re-proposed with an actual ring six weeks after filming the show.
The couple also said during an episode of the "Your Poor Dad" podcast last year that Nate never issued actually issued an ultimatum, per the show's format, but a producer made it seem that way.
Nate said: "One of the first questions I get is 'Nathan, so tell us why you issued the ultimatum?' and I'm like, 'Tell you why I did what? What did I do?' I didn't know. I was like, 'Wait I issued...' They're like, 'Yeah, you issued the ultimatum.'"
Lauren and Nate added that they were uncomfortable with the trial marriage process, which they said they were only told about during filming, and they didn't want to live with Colby and April Marie, who they were likely to be paired with.
"It was just getting more and more like, 'Hey, what the hell did we get into,'" Nate said. "Now we're also basically being paired up with, each of us, the person that we didn't want to be paired up with."
