The doorbell at Jen's house started to ring ... and ring ... and ring. Jen opened it and was surprised to see little Abby all dressed up as Cupid. "Gotcha! ... right in the heart!" Abby yelled gleefully! Jen laughed and asked Abby who she was. Abby replied that she was Cupid. Jen wanted to know where "Zeus" was and Jack peered around the corner. Then Abby started to chant, "Mommy's in love ... Mommy's in love." Jen grinned up at Jack and said to Abby, "Yes I am, Baby!" Evidently there was yet another teachers' conference that day and Abby had a day off school. She was spending the day with Jo and Vern who were waiting for Abby outside in the car. Vern tooted the horn and Abby rushed off. With a warm glow left from Abby's Valentine's wishes, Jen and Jack kissed. Jack then told Jen to close her eyes while he led her to the kitchen, which was totally decorated with balloons, hearts, lights and candles. When Jen opened her eyes to view the spectacle, Jack told her that he and Abby had been up since dawn decorating. A little later Jack, dressed in a red apron with white hearts on it, and chef's hat, served Jen a breakfast of heart-shaped pancakes and strawberries. Then he gave her a gift, which made Jen feel bad because she didn't have a gift for him. Jack told Jen that SHE was all the gift he needed. Jen opened her gift to find a beautiful heart-shaped watch/bracelet. Jack look lovingly at Jen and told her to take all the time she needed, but he wanted her to know that he would not take no for an answer. They both agreed that they wanted to forget all the bad stuff that had happened and wanted to move forward. They flashed back to the time that Jack had proposed to Jen when he was dressed in a Santa suit. Jen smiled at Jack and told him that he would never get the chance to propose to her again as she turned and ran upstairs. She returned shortly, dressed in a Santa suit, yelling "Ho Ho Ho." She ran up and plunked herself in an awestruck Jack's lap, pulled off her cap and beard, and told Jack he would get what he wanted. She told him that he was the only man she had ever really loved and that she still did. She bent down on one knee and asked him to marry her. Jack got down on the floor with her and accepted her proposal with a big hug. She urged him to make love to her, saying she wanted their new life to begin immediately. Jack gently picked her up and carried her upstairs.

While packing to go to Paris, Belle sadly looked at a picture of her and Shawn. Rex came by with a Valentine's gift for her from Shawn. Belle believed that Shawn must have arranged it before they had broken up. Rex urged her to open the gift which turned out to be a carving of a snowman. Looking at the carving reminded Belle of the time that she and Shawn had built a snowman together. Rex asked her if she really wanted to go to Paris. But before she had a chance to answer, the driver arrived to take her to the airport and Belle gathered up her luggage and rushed out to the car.

Shawn and Cassie were at the Brady House drinking tea. Shawn was totally enraged about Larry and told Cassie that he wouldn't feel safe until Larry was dead. Cassie, in her usual self-serving manner, reminded Shawn that it was Valentine's Day and thought that maybe they should have their own private party. Just then Mimi showed up with a gift for Shawn from Belle. Needless to say, Cassie was not at all pleased by this turn of events. Mimi called Cassie "Space Girl" and told her that she was aware of what Cassie was up to. Mimi then urged Shawn to open Belle's gift which turned out to be a book that Belle had made by copying certain pages from her diary. Shawn started to read the book to himself. The first thing he read was about the snowman that he and Belle had made. Cassie rushed to Shawn trying to stop him from reading it, but Mimi held her back. Mimi told Cassie that it was time for the two of them to leave Shawn alone, and all but dragged Cassie out the door. Not to be outdone, Cassie looked back at Shawn and said she would call him later ... but Shawn, full enrapt by Belle's gift, totally ignored her. Sometime later, as Shawn was reading the book, Alice dropped by with flowers for Bo and Hope. Shawn told Gran about Belle's gift and Alice pleaded with Shawn to stop Belle from leaving. Shawn planted a kiss on Alice's cheek and sped off to the airport. Later, we saw Shawn arrive at the airport only to be told that the plane had already departed. On the plane we saw Belle sitting alone, saying "Goodbye Shawn." Meanwhile back at the Brady House, Gran was listening to music and talking to a picture of her and Tom ... wishing Tom a Happy Valentine's Day. Unbeknownst to her, Larry was lurking in the basement, doing something to the furnace and the pipes. He mumbled to himself that when the Brady's got home, they would have a humdinger of a present waiting for them. He sneered at the fact that "Matriarch" Alice Horton was upstairs all alone. He chuckled to himself that a little carbon monoxide was all she needed for a one-way ticket to Tom-Tom Land. Upstairs, Alice had fallen asleep.

Bo and Hope woke up after a wonderful night at Green Mountain Lodge. Bo went to pour them a bath and while he was gone, there was a knock at the door. It was a delivery of roses and a heart-shaped box. Bo entered the room and yelled for Hope not to open the box. A frightened Hope thought that maybe the box was from Larry, but Bo assured her that it was from him and that he wanted to be there beside her when she opened it. The box was filled with memorabilia of their life together. The first thing Bo took from the box was a miniature motorcycle (flashback of a much younger Bo and Hope and his bike). Hope then took out a small carrousel and they remember the carnival and the kissing booth. Bo said that first kiss sealed his fate. Then they took out a tiny music box and they kissed. A while later, they were lying in bed wondering what would have happened if they had not met when they did. They both agreed that they were destined to be together and would have eventually met at some point in their lives. A fantasy unfolded as we saw Bo in The Blue Note Bar talking with a friend (played by Michael Buble). Bo turned to leave the bar and passed Hope who was on her way in. A few minutes later Bo came back in and complained that someone had hit his bike. He found out that it was Hope, who of course in this fantasy, was a complete stranger to him. His friend told him to go and ask the girl to dance. He went and introduced himself and Hope apologized for hitting his bike. She handed him her father's business card and told him to call with the cost of repairs to his bike. Before he headed to another room, Bo's friend suggested again that Bo dance with the girl. As the song "That's All" started to play, Bo asked "Princess" to dance, telling her it was payment for his bike. They headed for the dance floor to dance and when the song was over, she kissed him. Back in real time in Green Mountain Lodge, they two lovebirds were sure that if they had not met when they did, it would surely have happened sooner or later. Then they got out of the bed, both wrapped in their sheets, and danced .....

Shawn was rushed to University Hospital after collapsing at Salem PD from the poison pills. Roman became suspicious at hearing Rex tell Cassie that families protect one another 'no matter what.'
