As the fourth season began, the answers to two surprise marriage proposals were revealed. Beau turned down Elena's proposal to elope, confessing to her his feelings for Kerri. He knew Elena's proposal had been a last ditch attempt to save their relationship, but he couldn't deny that the two of them had been drifting apart -- and that his feelings for Kerri were growing more serious by the day.

Giselle was initially reluctant to accept Vincent's offer as well. He was still married to Martine! After giving the idea some thought, Giselle came to see the potential benefits -- both personal and professional -- in accepting Vincent's proposal. She agreed to remarry her ex-husband, and the two returned home to St. Laurent elated, despite their business trip to Vail ending in little success.

After months of on-again, off-again behavior, Elisabeth and Remy decided to give their relationship a second shot, but agreed to take things slower this time. Josie got a job working at the club with Remy. She hoped it would help the two of them grow closer, but when she learned he was back with Elisabeth yet again, she gave up her pursuit of him once and for all.

Josie was nearly assaulted by a drunk while walking home from the club one night. She was rescued in the nick of time by Roderick Wallace, a dumb jock who represented everything she hated. Roddy had a history with Josie's friend Eden. Josie was harsh on him, knowing that Roddy was a liar, a druggie and a serial cheater. Still, after he went out of his way to treat her with kindness, she saw a new side of him.

After their harrowing ordeal with Hal Roman, Charlie and Erin returned home with their new baby, a daughter they named Summer. They were happy to be safe and healthy, but felt guilty for their feelings, knowing Hal had kidnapped Priscilla Domingo and was still on the run.

When Kerrigan saw Charlie and Erin together with their child, she was more determined than ever to move on with her life and put her past with Charlie behind her. She felt bad for coming between Beau and Elena and was careful not to rush into anything too quickly, despite her attraction to him.

Elena lashed out at both of them, but she had more important things to worry about. She found a surveillance tape from the night of the Masquerade Ball in Giselle's office, and was determined to find out what was on it before Giselle returned from her business trip. On the tape, Elena was surprised to see that it was Monique Champlain who had pushed Nelson Fletcher to his death. Monique maintained her innocence and Elena wanted to believe her, but with the evidence stacked against her, Monique could find herself in serious trouble for the crime, especially if Giselle chose to use the tape against her. Elena kept the surveillance tape for safekeeping, while she decided what to do about Monique.

While Sonya and Jasper continued to search for the whereabouts of Hal and Priscilla, Charlie and Erin tried to settle back into a normal life, but the lingering threat of Hal reappearing in their lives was unsettling. After an aerobics class one afternoon, a stranger began to chase Erin and Elisabeth across the parking lot. Erin was sure it was one of Hal's associates, but it turned out to simply be an agent interested in working with Elisabeth.

Elisabeth attempted to get her modeling career back on track, but her agent, Pierce Shepard, wasn't exactly the most reputable of talent scouts. He tried to convince Elisabeth to star in a commercial for a herpes medication, but Elisabeth was too mortified to commit to the job. Pierce attempted to apologize, instead offering her a new gig: a model-search reality show. Elisabeth found the opportunity too exciting to pass up. Remy was convinced Pierce was a slimeball and warned her against it, but Elisabeth went against Remy's wishes and accepted the offer.

After returning from their business trip, Vincent immediately set about ending things with Martine -- so he could move on with Giselle. Martine was furious, but Vincent blackmailed her into agreeing to a divorce by threatening to reveal her involvement with Pete Sorenson and Derek Wolf. Martine was forced to sadly accept the dissolution of her marriage, and wondered what would happen to her and Josie. Martine tried to mend her relationship with Josie, but her daughter was angry that her life was being thrown into chaos once more due to her mother's actions.

At Kerrigan's urging, Martine and Josie enlisted in a wilderness retreat called the Pathfinders program. Josie was against the idea, but Martine wouldn't take no for an answer. Things went better than either of them anticipated, and after several therapy sessions with the program's counselor, Tyson LeBrock, the two made some inroads in repairing their relationship.

Josie ran into a familiar face at Pathfinders. It was Roddy Wallace, the arrogant classmate of hers who had rescued her from an attempted rape. Roddy and Josie grew closer while working together at their camp, bonding over their dysfunctional family lives. During a nature hike, Roddy and Josie teamed up, while Martine was forced to pair up with Tyson. After Roddy came to Josie's aid once more -- this time saving her from a menacing snake (and a sprained ankle) -- Josie realized he wasn't the same jerk he used to be. Josie gave into her physical attraction to him, and when the two finished their hike, Martine suspected something was up.

Late that night, Josie couldn't sleep. While wandering around the camp in the night, she witnessed her mother getting intimate with Tyson LeBrock and was enraged, deciding her mother hadn't changed one bit since they began the Pathfinders program. Josie ran away from camp and from the program entirely in the middle of the night. When Martine discovered Josie was missing, she left as well, sad to be leaving what might be developing with Tyson, but intent on trying to repair the damage she'd caused with Josie.

Upon Giselle's return, the animosity between her and Elena carried on, with Monique Champlain caught somewhere in the middle. Elena was trying to save Monique from being blackmailed by Giselle, but Elena soon realized Monique was far more troubled than she originally thought when she witnessed her employee doing what appeared to be cocaine. Elena followed Monique after work, seeking answers. Tracking down Monique led Elena to a place she never would have expected -- a strip club just out of town.

Meanwhile, with Martine out of the picture, Vincent and Giselle announced their engagement to the family. The family was stunned by the news, but In spite of their disapproval and the chaos surrounding the Highwind, they forged ahead with their wedding plans. Giselle even forced her pawn-by-blackmail, Monique, into being her Maid of Honor, since she had no other "girlfriends" to do the honor.

Elena confronted Monique about all her secrets -- her drug use, her second "job", and how she had pushed Nelson down the stairs at the Masquerade Ball. Monique admitted she had a problem, but insisted that she wasn't a stripper (she only bartended at the club), but more importantly, insisted that killing Nelson Fletcher had been accidental. Nelson was a frequent visitor to the strip club who had harrassed her on numerous occasions. When he got grabby at the Masquerade, Monique had tried to push him away, only to have him lose his sense of bearings during the blackout and fall to his death. Elena believed Monique, and agreed that they needed to destroy the surveillance videotape of that night to set Monique free from Giselle once and for all.

Giselle gleefully tormented Monique with her wedding demands, leading to a rapid increase in Monique's drug usage. Monique didn't take the punishment lightly, however. When Giselle made it Monique's duty to plan Vincent's bachelor party, Monique set about throwing him a crazy party at the strip club. While at the party, Monique bonded with Remy Ormand, who had just broken up with Elisabeth yet again. The two of them had a drug-fueled hookup in the club, but their wild night ended early when Beau and Remy were forced to carry a drunken Vincent out of the club.

Monique anonymously sent some shocking photos of Vincent's bachelor party to Giselle, but Giselle refused to get angry over her husband's partying, knowing that was exactly what Monique and Elena must want from her. The wedding would go forward...

On the day of the wedding, Elena and Monique destroyed the surveillance tape -- Giselle's evidence against Monique -- by throwing it into a lake. Monique agreed to quit the Highwind (and her drug habit) after the wedding.

At the chapel that day, Elena and Monique stealthily locked Giselle in the Highwind vault right before her wedding, hoping to stop the inevitable. A nervous Monique turned to her drug habit yet again, doing lines of cocaine in the bathroom right before the ceremony was set to begin. As the wedding was set to begin, Giselle came racing back from the vault. She'd used a security override to escape and had foiled Elena's plot.

The wedding march began. Just as they were pronounced man and wife, Vincent Guthrie's marriage to Giselle was derailed by Monique Champlain. The drugged-up Maid of Honor collapsed and took a candelabra down with her, igniting the altar, and more specifically, the bride, into a ball of flames...

Charlie and his wife, Erin, tried to get their lives back on track with their new daughter, but before they even had time to settle in, Erin was kidnapped once again. Charlie knew at once that it must be the work of Hal Roman, coming to finish what he had started with Erin and Summer. Charlie rallied all the support he could find and was annoyed that his parents seemed more concerned with their own wedding plans than in helping him locate his missing fiancée.

With Sonya, Jasper, and Abe on his side, however, Charlie tried to track down Erin and Hal. They found a clue at the airport -- a surveillance tape showing Erin and her kidnapper boarding a flight to Rio de Janeiro. Charlie immediately booked a flight there to continue his search for her.

Erin awoke to find herself trapped in Hal's new research facility. She had been drugged, and continued to be sedated by Hal's goons while she searched for answers. Erin found that she was being held captive alongside Priscilla Domingo. Priscilla told Erin everything she knew about Hal's research. Hal came to find Erin and told her the truth about himself and his motivation for going after her. He had a cancerous brain tumor and had abducted both Summer and Priscilla's child to try to "grow" a cure that would be carried in the childrens' genetic information.

Erin was furious that he'd put her through such a harrowing ordeal for his own selfish reasons, but Hal tried to convince her that she was the selfish one, saying what a medical breakthrough his research would become. But first, his assistant, Stella, was about to attempt a dangerous surgical procedure to remove the rest of his tumor...

While searching for Erin and Priscilla, Sonya and Abe grew closer. The two of them were interrupted from their fling, however, by the news that Charlie and Jasper had a lead in their search for Erin. The four of them raced to Hal's villa, desperate to free their friends from the crazed doctor.

Little did they know, Hal was in no condition to carry out a defense against them. He was currently in surgery, his assistant Stella doing her best to perform risky brain surgery on him. The rescue party crashed through the gates and broke into the clinic. Erin and Priscilla were freed from their captivity, but Erin wanted to be sure Hal wouldn't escape again.

The group barged into the operating room, where Hal was defenseless and unconscious on the operating table. Erin shot Hal on the table, making sure he wouldn't be able to harm her again. Stella was horrified as she watched Hal slip away and die on the table. She pulled out her own gun and fired wildly at Erin for retribution. Unfortunately, her gunfire connected with Sonya Cortes...
