At Company, Coop and Ava agree to stay out of each other's business while Lizzie tries to convince Ava they should be friends. Ava doesn't want to be any part of it. Lizzie tells her she wants to start being nice to Ava since Coop is always so nice to Lizzie's family's employees. While Coop is off speaking with Ava, Lizzie finds the engagement ring in Coop's jacket. She leaves Company to go get ready for that evening's dinner at The Club with Coop. When she's gone, Ava tells Coop they should just be friends. Coop can show her baby pictures and she'll tell him about her dates. Coop tells Ava he might propose to Lizzie. Ava tells him to do what he thinks he should do. Lizzie goes to the Spaulding mansion and tells Grandma Lillian about the impending proposal. Lillian tells her she's happy for her but wants to make sure Lizzie doesn't get hurt if Coop is only going to marry her out of a sense of obligation. Lizzie tells Lillian she doesn't want to end up alone, feared and hated the way her father Phillip had.
Meanwhile, Alan and Beth, Mallet and Dinah, and Harley and Gus are all on different parts of the island. Alan and Beth arrive at the Spaulding retreat and continue their sparring banter. This leads to Alan's confession that he feels he might have a chance, with the new baby, to have a child who actually loves him. He also presents Beth with a white wedding gown. She tells him he is loved by both the baby, and the baby's mother. After more banter and a few passionate kisses, Beth notices coffee cups and Springfield newspapers on the table. Everywhere the name 'Spaulding' appears in the paper, the name has been circled. Alan brushes it off as the help keeping up with news back home.
It takes a few minutes, but Dinah finally gets it through to Mallet that she did not kill Alan-Michael. She explains how she regrets her past and is ready to move on. She confesses that she and Alan-Michael had eventually begun conspiring to push Harley out of Spaulding. They leave the jet and return to the hotel area.

When the officer leaves, Dinah thanks Mallet for not giving her up. They head out to look for Gus and Harley so Dinah can apologize to Harley.

Gus is very resistant to the idea, but eventually comes around more when Harley shares her theory that Ross was killed because his private investigator discovered Phillip was still alive. Someone didn't want Ross to reveal the truth. They go to the Spaulding retreat and confront Alan with their accusations. While there, Harley notices the Springfield papers as Beth had. Beth notices the crossword puzzle in the paper had been filled out in red ink, just as Phillip always did it. And it is in Phillip's handwriting! She screams at Alan, "What is the truth?"

Mallet is trying to reassure a very upset Dinah that Phillip can't hide forever--justice will be served. The sentiment doesn't console Dinah who can't comprehend how Phillip could let something like that happen to her father. Dinah soon stalks off and Mallet is left alone with Harley. Mallet finally confesses to Harley that he's known Phillip was alive since her wedding last year. A shocked Harley demands to know why he didn't say anything. Mallet tells her that he lost Phillip--he was long gone and Harley was just so happy that day. Harley tells Mallet that he has to come clean with Dinah. Mallet knows she's right but is concerned that Dinah could blame him for ultimately causing her father's death. At that point, Gus enters with news--a plane recently took off from an unoccupied house; it could be Phillip. At that point, a policeman comes over to ask Mallet questions about Dinah.

Gus assures her that they all have demons. His talk seems to help Dinah.
A little later, Dinah is talking to Mallet about how she finally understands the agonizing grief that led Harley to seek comfort with Mallet when they thought Gus was dead. At that precise moment, Gus walked by and overheard everything. In shock, Gus angrily shatters the glass that he's holding. When Harley, and a little later Harley and Mallet come on the scene to help Gus bandage his hand, Gus keeps silent about what he heard. Instead he asks Harley if she remembers how they agreed to be open with each other. He then asks to speak to his wife alone. Alone, Harley asks an eerily silent Gus if there's a problem. She wonders if it's his leg and if he needs a... Gus finishes the sentence for her; she wants to know if he needs a pill. He then starts talking about how they agreed that trust and truth were everything. He used to believe that. Harley thinks she's knows what's wrong with him. She thinks he's too afraid to let his guard down because he's anticipating their next crisis. At that point, Dinah and Mallet return and someone suddenly knocks on the door. It's a preacher who was there for a renewal of vows. The group figures it must have been for Alan and Beth but they're gone now. Suddenly Harley gets an idea---why don't she and Gus renew their vows? Gus isn't too comfortable with that idea but Harley states that it'll give them a chance to reaffirm their love. Dinah and Mallet go to leave, with Mallet giving Harley a gentle kiss on the cheek. Gus can't help but envision that kiss as seductive. Alone, Harley tries to convince the unenthusiastic Gus to go along with the ceremony. She tells him she wants to feel closer to him and celebrate their love after everything that's happened over the last two years. She tells him to give her one reason, just one, why they shouldn't. Gus keeps quiet and agrees to renew his vows. However, when the time comes, Gus can't go through with it and storms out in the middle of the vows. Harley goes after him and urges him to put the past behind him. Gus maintains that some things you can't get over. Harley then starts talking about why she loves Gus--he's her hero, a quirky, flawed hero. She tells him how devastated she was when she thought he was dead. She hardly wanted to go on living without him. He's her life. She tells him she loves him and he's all she'll ever want or need.
Meanwhile, Mallet and Dinah are in Ross's suite. Mallet is telling Dinah that she knew Phillip was alive for the past year. Dinah's upset--not so much because he kept quiet but because he's saddling her with this now. Mallet points out that he knows what keeping secrets does to a relationship. He then points out that when she told him about her plotting with Alan-Michael, he forgave her. Mallet needs to know if Dinah can forgive him. If she can, that's great; if not, then that's that. An upset Dinah finds a letter among Ross's things addressed to Mallet. In the letter, Ross gives his blessing for Mallet to date Dinah and ask him to take care of her. An extremely touched Dinah hugs Mallet. He asks if this means he's forgiven; she assures him there's nothing to forgive him for. They then make love.
Meanwhile, Gus tells Harley he loves her. He tells her he regrets vanishing on New Year's Eve. He's sorry he wasn't there to ease her pain. They both admit that they can't see their future without the other in it. Afterwards, Gus and Harley make mad, passionate love. Later, a restless Gus goes downstairs and gets himself a drink. He then goes looking for pills and takes one.
