Carter paced around Il Giardino, looking at the setup for the wedding. He received a video call from Paris telling him that she could "not wait to be Mrs. Paris Walton." As the call was ending, Ridge approached and commented that Paris sounded like "an excited bride." Carter agreed. "What about the groom?" Ridge asked. Carter was uncharacteristically quiet.
Ridge looked around at the décor for the wedding -- a French motif -- and seemed puzzled by it all. Carter claimed the theme was his idea, and he announced that he would be taking Paris to Paris for their honeymoon. Ridge was unmoved by the witty display of affection. Ridge asked Carter what he was doing because he knew, or rather believed, that Carter did not love Paris.
In a room elsewhere at the restaurant, Hope marveled at how Paris would be a married woman by the end of the day. Hope explained that Liam couldn't attend the wedding because he was out of town on business. Paris appreciated Hope's support but wished that Grace supported her decision to marry Carter. Paris commented that Hope might be the only one in attendance that truly supported her choice to get married. Paris shared that she had invited someone else to the ceremony -- Bill Spencer.
Hope was surprised that Paris would invite Bill, but Paris explained that Bill was a big supporter of her work with the Forrester Foundation, and she thought Bill might want to attend. Zende popped his head into the room and asked if he could have a moment alone with Paris. Hope nodded and left the two to talk.
Zende apologized for showing up early. He told Paris that he wanted to give her "something old school" for her wedding, a corsage. Paris thanked Zende for being there for her. Zende was disappointed to hear that Grace would not be attending the wedding. As if on cue, the door to the room opened, and Grace stepped inside. Grace said nothing, instead walking straight to Paris and giving her a warm embrace. Grace said that she loved her daughter, but she admitted that she was worried that Paris might get hurt by Carter.
"Carter is becoming my husband, the father to my kids, your grandchildren," Paris replied. Grace insisted that she was trying to protect Carter. "That man is running from something," Grace snapped. Paris demanded that her mother stop. A knock sounded on the door, and Hope announced that it was time for the ceremony to start.
In a separate room, Ridge continued to ask Carter about his decision to marry Paris even as Carter was putting on his tuxedo. "You're my best friend. I want to make sure you thought this through," Ridge said. Carter robotically replied "I'm ready. I want a family, I want a partner, and I'm not getting any younger, right?" Without ever mentioning love or Paris' name, Carter then added, "I want this. I need it."
Elsewhere, Charlie walked around the transformed dining area at Il Giardino and marveled at how beautiful everything was. In particular, he loved the Eiffel Tower cookies. He wished that Pam could have been there to see it and bemoaned the "knitting retreat" that she had gone on.
Charlie was surprised when Bill showed up, as was Zende when he walked into the dining area. Bill was somewhat surprised to see Zende in attendance. Zende shared that Paris was "special" to him, and he wanted to support her.
As Quinn stared in disbelief at Eric and Donna in bed together, she slowly put the pieces together that linked Eric's supposed interest in Pickleball and his rapid heartbeat. "I'm sorry you had to find out this way," Eric staid nonchalantly. "I was worried about you," Quinn shouted, ranting, "You're not playing Pickleball, you're having an affair with Donna."
Eric and Donna eventually got out of bed and put on their clothes. Eric insisted that he had planned to tell Quinn, a statement that Donna backed up. Unable to make eye contact with her husband, Quinn said, "You've been lying to me for weeks." Eric asked Quinn what she'd meant about his heart rate having been elevated. Quinn grabbed Eric's hand and removed the ring that she had given him.
Bridget, who had been silent, informed her father that the ring Quinn had given him was a smart ring that had been tracking his heart rate and other vital statistics. "All this time, I thought you were in danger," Quinn said as she fought back tears, adding, "You were betraying our marriage." Quinn struggled to understand why Eric had chosen to step out on their marriage. "How is this okay when I... when I've been working so hard to fix what happened between us?" Quinn asked. Eric insisted that he had forgiven Quinn for her affair with Carter. "[What] I've been struggling with [is] the fact that you're in love with somebody else," Eric replied.
"Everything's easier with Donna. I trust her," Eric said. Eric asked Donna and Bridget to leave the room. They did, but as Bridget exited, she looked back in disbelief at her father. Eric buttoned up his shirt as Quinn burst into tears. "Is this really it? Is this really the end of our marriage?" Quinn asked.
Eric and Quinn both confessed that they'd thought they would always be together. "How is this fair? I've been begging you," Quinn said angrily. She said, "I've been working so hard -- I've been doing everything possible. Here you are doing the exact same thing to me that broke us apart in the first place!"
Eric said that he hated being "this man who cheats on his wife." He swore that he had planned to tell Quinn about Donna later that day. "I'm completely and utterly shattered," Quinn sobbed, stating, "I thought you were the most loyal man in the world." Eric replied, "I thought I was, too." Eric explained that everything had changed when he'd tried to talk to Quinn about Carter's wedding. Eric said, "That's when I realized... the more you tried to keep our marriage together, the more I was drawn away from you. I'm realizing that I have to let go of my love story with you." Eric urged Quinn to realize that she had to let go of hers, as well.
"We were meant to be together... until we weren't," Eric said. Eric admitted that sneaking off to be with Donna was wrong, but he declared that the feelings he had for Donna were not wrong. Eric told Quinn that her feelings for Carter were also not wrong. Quinn said that she wasn't sure that she knew how to let go of Eric. Eric told her to focus on the fact that she loved Carter. Quinn closed her eyes and nodded, acknowledging for the first time her true feelings for Carter. She breathed a sigh of relief as she realized that she no longer had to fear hurting Eric or how his family would respond.
Eric told Quinn that he had cherished their time together. "You charmed me with your wit and your beauty and your talent [and] your intellect. I'm proud I was your husband," Eric said softly. Eric asked Quinn to see the beauty in their heartbreaking situation. Eric then told Quinn, "Right down the beach, this man that you love is about to make the biggest mistake of his life." Quinn slid off her wedding and engagement rings. "I think I'm gonna keep the big diamond," Quinn said with a slight smile. "And so you should," Eric replied.
"You're meant to be with Carter. If you hurry, you won't be too late," Eric added. Meanwhile, at Il Giardino, the "Wedding March" began to play.
