Below is what happened on Episode 15 of 90 Day Fiance: The Other Way's fourth season.

GABRIEL and ISABEL

Gabriel was shown getting ready for his wedding, knowing his sister Monica wasn't going to attend. Gabriel was running late, but he didn't plan on yelling Isabel the truth because he didn't want to upset her or take attention away from the bride. He therefore planned to tell everything that Monica was sick.

Gabriel loved seeing both sets of parents in the same place, supporting his union with Isabel, but he felt a little nervous about the ceremony.

Meanwhile, Isabel was getting her hair and makeup done. She didn't know what made Gabriel so late, but she was excited to get the show on the road.

"At this moment, I feel like I'm in a dream," Isabel said.

Gabriel said he sacrificed everything he had for Isabel and moved to Colombia for her. He couldn't believe someone had accepted him for who he is and wants to be with him forever. Gabriel gushed about how he was so happy.

Isabel told the cameras how she felt stability with Gabriel and wanted to be with him for the rest of her life.

Gabriel and Isabel then exchanged vows and rings, and they were officially married!

Gabriel later told Isabel at the reception, while they were eating dinner, that Monica didn't attend the wedding because she was upset. Isabel asked if Monica had a problem with her or their relationship, and Gabriel said he had no idea.

Isabel said Monica owed Gabriel an explanation but she wasn't going to let the news -- or Monica's absence, in general -- ruin her night. Isabel was beaming with happiness and excitement, and her parents also said this marriage was a dream come true for them.

"After everything I've been through, I feel like I'm finally where I'm meant to be. I am really excited for my new adventure with my wife because we have a lot of love for each other, and I just can't wait to grow together," Gabriel shared.

NICOLE and MAHMOUD

Mahmoud was shown taking Nicole, who had been living in Egypt for five months, to a garden near the water.

Nicole said she was so excited Mahmoud had agreed to move to America, and so they were just waiting for his visa to be approved. Mahmoud never wanted to live in the United States, however, and so Nicole wondered if he'd be happy.

Mahmoud, meanwhile, feared their fighting and arguing was just going to get worse. Nicole said he needed to be less of a "dictator" and let her wear less conservative clothing, especially in the summer, but Mahmoud said he didn't want other men looking at his wife.

Mahmoud admitted he wasn't going to make any promises, but Nicole didn't think it was fair -- to either of them -- that she couldn't be herself in the relationship.

Mahmoud told Nicole that he hated it how she booked a flight every time she was mad at him. Nicole then accused Mahmoud of having "little chats" with other women in different countries.

Nicole apparently went through Mahmoud's phone and found messages in which he had asked one a women how old she was, what she was doing, and if she made it back to her hotel room alright.

Instead of explaining himself, Mahmoud angrily asked Nicole why she had gone through his phone.

"You think that's okay?" Mahmoud asked.

"No, I don't think it's okay. But I think it's as okay as you having chats with other girls," Nicole clapped back.

Mahmoud claimed the messages were about work, but Nicole said Mahmoud had crossed the line when he suddenly took off -- without his phone -- and failed to tell Nicole where he was going.

At that time, Nicole went through Mahmoud's phone and found his exchange with a woman from China. The woman was trying to sell Mahmoud a television, and so she thought it was weird he was asking about her age and what she was doing. Mahmoud also allegedly sent her emojis.

"It's not your business to ask most of that stuff... [The hotel part], to me, was pretty inappropriate... [and] seems pretty suspicious," Nicole said.

Nicole said she was a little angry because it didn't make sense for Mahmoud to ask a random girl such questions, and Mahmoud claimed he didn't know why he had done that and it was "a stupid thing" to do.

Mahmoud therefore apologized to Nicole for his actions and said he didn't want any other woman in his life, and so she decided to call it a "mistake" and just move on from the "ridiculous" situation.

Mahmoud also said he was going to try to change and not control Nicole in the United States. She thanked him for trying because she didn't think their bickering was healthy.

"I don't know how it will be, but I have to take this chance to show her that I love her," Mahmoud told the cameras. "If it works, I get the best thing I [could] ever want."

JEN and RISHI

Rishi admitted he was heartbroken and not ready to accept the fact he and Jen were broken up. He was still grappling with the fact Jen had dumped him.

Rishi therefore visited his local temple to pray because he said he felt "hopeless."

Rishi's parents did not approve of him marrying Jen due to her age and refusal to live in a joint household. Rishi's astrologist friend warned him that the wedding was never going to happen and he needed to accept reality.

Rishi insisted that he loved Jen so much, but his friend claimed there was no future for the pair and Rishi needed to let Jen go. Rishi realized in that moment maybe the stars were aligned and be and Jen weren't meant to be together.

"But I believe in love more than astrology. I'm not ready to give up. I'll fight for us," Rishi said in a confessional.

Later on, Jen said Rishi had been reaching out to her like they're still together and so she needed to remind him that it was over and she planned to leave. Jen said she was in "survival mode" and needed to move on from her ex.

Jen told the cameras that needed to leave the country to prove to Rishi that their romance was over.

The pair then met up at a cafe, and Jen wanted to make sure that they were on the same page.

Rishi confessed it was hard for him to accept the circumstances, but Jen told him that they both needed to move on with their lives.

"I decided I'm going to go back to the United States... soon," Jen revealed. "This is the last time we're going to see each other. At this point, it's the best thing for both of us."

After three years of dating, Rishi was devastated his relationship wasn't going to work out. Jen assured Rishi that she wanted him to be happy, and she teared up during the conversation.

Rishi wanted to say, "Don't leave me," but it was hard for him to express anything in that moment.

Jen asked Rishi to let her go, and then he started to cry. Rishi told Jen that he'd do it for her and would remember their beautiful memories together. Rishi told Jen that she's a beautiful person and has a beautiful heart, is why he had fallen in love with her in the first place.

Jen wanted to think Rishi could be her forever person, especially if she tried hard enough, but she felt she had no control over the situation.

Even though the future looked grim, Rishi was determined to keep fighting for Jen. He said he was going to do whatever it takes to win her back.

KRIS and JEYMI

Kris and Jeymi had gotten into a big fight over money, with Jeymi raising her voice and Kris storming off. Jeymi said she had to raise her voice so that Kris would listen.

But Kris was upset because her son was in jail after a drug arrest and she said that's why she had missed Jeymi's birthday in Colombia. Kris cried about how Jeymi didn't seem to care about her situation at home and was being selfish. Kris said Jeymi hadn't been working and so she was doing more for their marriage.

"I send her money all the time," Kris claimed.

But Jeymi said she was in a financial hardship when Kris had allegedly told her that she'd never need to worry about money.

Jeymi said she was in bigger debt than ever for trusting Kris. It also bothered her that two weeks in Alabama turned into five months. Jeymi also believed Kris' son's arrest had nothing to do with Kris missing her birthday.

"The fact she says she sends me every penny she makes is a total lie," Jeymi told the cameras. "When I am right, she gets mad. I tried to talk to the person I love, but she doesn't want to listen to me."

Kris then reunited with Jeymi, and Kris said Jeymi couldn't talk nonstop without letting Kris respond to give her part in it or defend herself. Kris told Jeymi that she could afford a $400 per month apartment and Jeymi had found a place that's $100 more expensive per month.

"I'm done. I'm done with this bullsh-t and you being selfish and all about yourself," Kris yelled, adding how her son would come first always.

"I'm done. I'm moving out, I'm getting my sh-t and I'm moving out. I'm done! You're a selfish, selfish person as you don't give a f-ck about anyone else! I'm done! Find somebody else to pay your f-cking bills!"

Jeymi was left upset at her birthday party. She said she was tired and never wanted Kris for her money or her things.

When Jeymi approached Kris, who was sitting in an SUV, Kris shouted at her to "get the f-ck away" from her. When Jeymi didn't back away, Kris kept at her through the car and pushed her. Jeymi accused Kris of being crazy and said she could only see "hate" in her eyes.

Jeymi said it was never her intention to make Kris feel hate towards her, and then she started to bawl her eyes out.

THE CAST REUNITES FOR THE TELL-ALL REUNION

Before the Tell-All began filming in New York City, Gabriel admitted he didn't like Kris and wasn't looking forward to seeing her. He thought she complained too much and was "full of bologna."

Gabriel, however, said he's a fan of Oussama and it seemed he really loved Debbie and was a genuine person.

Nicole told Gabriel that she was no longer going to enable Mahmoud's insecurities. She was proudly wearing a dress with one sleeve.

Meanwhile, Daniele said she wasn't going to put up with Yohan's bullsh-t, and Debbie announced how she's "a work in progress" and was all about the accessories that day.

Shaun Robinson hosted the couples' Tell-All.

Daniele told Shaun that she and Yohan were still "technically married."

Jen revealed she and Rishi had been talking "a little."

Isabel said she missed Gabriel while he was in New York City and it felt like she was missing her other half.

When asked how he felt about Nicole's sexy ensemble, Mahmoud said she looked amazing but it wasn't the outfit he had picked out for her.

Kris and Jeymi apparently hadn't spoken since their blowout fight.

OUSSAMA ADMITS HE TRIED TO WIN DEBBIE BACK

Shaun asked Debbie and Oussama -- who participated via videochat from Morocco -- at the Couples' Tell-All in New York if they had been in touch since they left each other, and Debbie said Oussama had tried to communicate with her but she didn't respond.

Oussama claimed he had called Debbie "thousands of times" after their breakup and felt like Debbie didn't care.

Debbie said she needed to heal herself after what happened in Morocco and hit "the reset button." She called Oussama "a mean and unkind person."

Yohan advised Debbie to get Oussama a green card and let him work in America because she could help him out and allow a young man to thrive. Gabriel acknowledged how Yohan had a point because Debbie could be viewed as using Oussama to live in Morocco -- but no one thinks that way.

Oussama claimed he used to love Debbie -- and had a physical attraction to her -- but he didn't love her anymore, and Debbie snapped how Oussama doesn't even know what love means.

"There is no future for us, just to make things clear," Oussama said, adding how Debbie's age never bothered him because "souls have no age."

Debbie's son Julian joined Debbie onstage and alleged Oussama had sent Debbie 60 texts in two hours and it needed to stop. Julian was furious and called Oussama "a psychopath."

Julian called Oussama the "biggest bullsh-tter" he had ever seen in his entire life. Julian asked Oussama to get a job and stop preying on vulnerable, elderly women. Julian dubbed Oussama "a stalker" and was clearly furious at him.

Debbie said she had sent Oussama about $2,000-3,000 over several years for groceries and daily items, but Julian said there was "a snake" trying to get into Debbie's pocketbook for other reasons.

When Shaun asked Oussama if he wanted Debbie back, Oussama replied, "Yeah, I try before."

Julian told his mother that he wanted her to find a real man, and Debbie shared how she wouldn't respond to Oussama going forward.

"He'd have to move a mountain for me to respond to him. He could start by sending me an airline ticket," Debbie said.

But the cast, including Julian, begged Debbie to just cut the cord and forget about Oussama.

During a break from filming, Debbie said she noticed Jen had been batting her eyes at Julian. Julian told Debbie that he thought Jen was cute and so Debbie could give her castmate his phone number if she wanted to.

NICOLE and MAHMOUD GIVE RELATIONSHIP UPDATE

Nicole revealed she was living in Los Angeles alone and Mahmoud had his visa appointment in just under three weeks. If Mahmoud's visa got approved, he could come to the United States at any time.

Mahmoud said he was very happy about the situation, but Shaun didn't really believe him.

Nicole shared how she was going to support Mahmoud for a while, which he was okay with since they are "not one but two persons" as married spouses.

Nicole told Shaun that she'd never go through such hardships for a man or any relationship for anyone but Mahmoud.

Mahmoud then shared how he and Nicole were going to raise their child Muslim. Gabriel asked what the couple would do if their son or daughter doesn't want to be Muslim, and Mahmoud said he would teach his child about the religion.

"What if you have a daughter? Are you going to force her to wear a hijab?... I don't think you should force religion on a child," Gabriel announced.

Mahmoud said he didn't or wouldn't force anybody to do anything and that his religion and practices weren't any of Gabriel's business. Mahmoud said he and his wife would talk about such an issue in private and deal with it as a couple.

Mahmoud repeated how he would teach his child how to be Muslim, and then Nicole said the child could choose what he or she wants from there.

Gabriel accused Mahmoud of suppressing Nicole behind closed doors, and then Mahmoud said he was "done" and walked away from the conversation.
