It's not necessarily shocking that someone would be unattracted to a person they're marrying at first sight or worried that they've made a terrible mistake. It is, however, shocking to see a panicked Jamie Otis crumpled on the floor at her wedding reception after marrying Doug Hehner. Even though she chose an unconventional route to matrimony, the day was meant to be one of the happiest days of her life. Instead, Jamie was nearly inconsolable and insisted that the experts had failed her.The scene is almost funny to watch nearly a decade later considering that Jamie and Doug are still married and have two children. They have both publicly laughed about the scene, which has easily become one of the most iconic cringe moments in the franchise's history.Since the start of their marriage, Zach Justice made it very clear to both Mindy Shiben and viewers that he wasn't physically attracted to her. They also had a rocky honeymoon.Still, it was very surprising to watch Zach refuse to move in with Mindy in season 10 episode seven. Zach had excuses as to why he wanted to live apart, but they rang hollow. It definitely takes nerve to refuse to participate in a social experiment that requires vulnerability, for which you voluntarily signed up. Zach's choice marked the first (but certainly not last) time in Married at First Sight history that a participant didn't move in with their spouse, but insisted they were invested in the relationship.Heather Seidel and Derek Schwartz definitely had a tumultuous honeymoon. Heather got extremely angry with Derek for smoking, and their arguments eventually escalated to the point of Derek calling Heather an alcoholic. Their dynamic was undeniably toxic, though it was admittedly shocking when the pair decided to end their marriage after less than two weeks in season four episode seven. It marked the first time in Married at First Sight history that a couple quit the experiment early.Prior to season 15 of Married at First Sight, many cast members had been scared to tell their families they were participating in the experiment or neglected to tell them at all. But it was mindblowing to watch cameras capture Krysten Collins telling her dad she was getting married to a stranger when he showed up for what he thought was a formal event on her wedding day. What's more, Krysten was scared of her dad's reaction and wanted his approval. He ultimately gave it. (Perhaps he didn't want to run the risk of her running away?) We'll never know, but she did walk away from her relationship with her ex Mitch Silverstein on decision day.During Keith Manley and Iris Caldwell's wedding reception in season nine episode two, Keith's mom noticed Iris's dress was pure white and then confirmed that she purposefully chose to wear it because she was a virgin. Mama bear then chose to divulge the information to her son. To be clear, what shocks me about this has nothing to do with Iris's sexual history. It's the fact that Keith's mom shared that information with him right away. He's her son and she was looking out for him, sure. But Iris deserved time to tell her husband that information on her own. No matter, though. When Iris's marriage to Keith ended on decision day, she was still a virgin.During a friendly game of Never Have I Ever on the honeymoons, Olajuwon Dickerson admitted to the rest of his castmates that he has had sex with a mother and then had sex with the woman's daughter on a separate occasion. Olajuwon said he was a reformed player and he is still married to his wife Katina Goode, so he eventually won me over. But still, his confession is the definition of TMI. He volunteered this after asking the question himself, which is also just unnecessary.Throughout the experiment on season eight, married couple Kate Sisk and Luke Cuccurullo told viewers and experts alike that they hadn't yet had sex. Then in episode 12, Kate confessed to Dr. Pepper Schwarz that she and Luke actually had been doing so since their honeymoon.But that's not even the most shocking part. Kate also revealed that Luke got serious and quiet after sex and doesn't want to be around me. She explained that he usually left the room and didn't talk to her for a few hours after they were intimate. Kate assured Dr. Pepper that once she became aware of Luke's pattern, she would talk to him before they had sex to make sure he didn't feel obligation. He would tell her everything was okay and then proceed to act the same way when they were finished. Kate said Luke's behavior after sex made her feel anxious and terrible. I don't blame her, because this is a man who also told her that kissing her made him feel dead inside, per Kate in a previous episode. Luke's behavior and even his words may night have come from a malicious place, but his actions were still shocking to hear about because they were the complete opposite of what anyone wants to see from a partner after sex.In season 13 Episode 10, viewers learned that Jose San Miguel locked Rachel Gordillo out of their apartment after an argument one night. Rachel had accidentally called Jose another man's name while they were out. We later learned that she simply misspoke and said her cast member Johnny Lam's name — not while they were being intimate, but while they were all out together. Jose appeared to have a controlling nature in previous episodes and appeared to be passive-aggressive when he told her that even though he knew she wasn't home yet, he locked the door because he always secured his property at night. Jose clearly didn't make a mistake. Watching him try to defend his abuse made was top-tier cringe.Alyssa Ellman and Chris Collette essentially had one of the shortest relationships in Married at First Sight history. Alyssa refused to sleep in the same room as Chris on their wedding night. Though they went on their honeymoon with the other couples, it could be argued that their marriage was over in a few hours.To my knowledge, Chris didn't overstep any boundaries or mistreat Alyssa in any way — she just wasn't attracted to him. Her feelings are valid and she had the right to choose to end the experiment at any time. What was shocking was the way she treated and talked about Chris. Instead of talking to experts or kindly explaining to Chris that she didn't want to be with him, she'd tell producers, I hate him and act like the victim.She also expected to continue filming with the other couples in the apartment complex without ever giving her relationship a chance. Her behavior throughout the season was appalling. Though Alyssa constantly claimed she was a nice person, her actions consistently proved otherwise.Though Brandon Reid and Taylor Dunklin established a strong connection almost immediately, Brandon's struggles with the Married at First Sight filming process caused their marriage to fail. When all of the couples were packing to leave their honeymoon in Panama, Brandon began to argue with the production crew about filming him. In an interview, Taylor admitted that he was rude and abrasive to the crew and she didn't like that side of him. She said she talked to Brandon off-camera and told him that the person he was sometimes being on-screen is not somebody I really want to be married to. She said he responded negatively to what she said and threw his wedding ring aside before leaving the room. Then he cursed at the rest of the cast on the bus ride to the airport. And when they landed in Washington D.C in the next episode, Brandon abandoned Taylor at the airport, leaving her to move into their apartment alone. He eventually came back and continued the filming process in earnest — but is it a surprise to anyone that this union didn't last? Brandon was such an unbelievable man-child. On her way to her honeymoon destination with then-husband Tristan Thompson, Mia Bally was detained at the airport and later arrested. She had a warrant out for her arrest for charges related to allegedly stalking her ex-boyfriend and credit card fraud, Tristan said in the episode. The charges against her were eventually dropped and Tristan decided to stay in the marriage — but the pair went on quite an intense rollercoaster ride in their relationship. I suppose their breakup was inevitable. An unexpected arrest would create waves in even the most solid marriages.Season nine couple Beth Bice and Jamie Thompson had one of the most emotionally intense relationships in Married at First Sight history. That intensity hit a negative boiling point in episode 11 after Jamie embarrassed Beth by telling her to shut up in front of many of the other couples. Beth started acting withdrawn after the incident and no one confronted Jamie about his rude words. Days after the incident, while waiting for an expert to come to help them work it out, they got into another argument. At one point, a frustrated Beth shoved a table that Jamie's legs were resting on, and screamed because no one in the cast had defended her when Jamie spoke rudely to her. As shocking as the moment was, the two managed to move forward and are still married today.Michaela Clark and Zack Freeman were a season 13 couple who could never find harmony with each other. On the couple's retreat episode toward the end of the season, Zack decided to leave the retreat after he and Michaela had a fight about their future. Michaela got mad that Zack left at night instead of waiting until the morning, prompting her to take her anger out on the cast's accommodations. She stormed through the house, destroying furniture and screaming at camera people as they tried to document her. A producer ended up having to physically restrain her. It was definitely one of the scariest and most explosive moments in franchise history.Paige Banks got the rawest deal in Married at First Sight history when she married Chris Williams. I couldn't even pick a single moment because all of Chris's actions throughout the season were shocking in the worst way. He was just cringe personified. His emotional abuse of Paige started on the first night of their marriage and lasted until decision day. There is nothing funny about emotionally manipulating a woman to have sex with you by hinting that you might find her more attractive afterward — but Chris did that. The biggest bombshell dropped during their honeymoon when he revealed that an ex he'd hooked up with while also participating in the Married at First Sight casting process had gotten pregnant. Chris eventually told Paige that he wanted to break up with her and try to make it work with his ex, but he kept changing his mind and stringing Paige along. At one point, he told Paige he wanted to break up with her because he was scared to fall in love with her. Unfortunately, Paige fell for his lies time and time again, placing faith in her vows as she'd made them before God. On decision day, Chris announced that his ex (who appeared on camera to meet Paige) had a miscarriage. He tried to convince Paige that they shouldn't make a decision either way whether to end their marriage or not. Luckily, producers took an unprecedented step and helped Paige realize that she knew in her heart that she needed to get a divorce. Paige spoke her truth and eventually healed from that disaster of a marriage.
