Liam Ridley

In "Our Turn Now", Fallon (Elizabeth Gillies) sets up Liam as Sam's date to her faux wedding to Jeff (Sam Adegoke). Sam (Rafael de la Fuente) and Liam hit it off, making Fallon's brother Steven (James Mackay) jealous. Liam eventually admits that he is not gay, and encourages Sam to seek out Steven. Turning the tables on the Colbys, Fallon announces to Jeff that their new marriage is invalid since she met and married Liam the night before at city hall. Though their annulment is in the works, Liam agrees to attend Fallon's grandfather's funeral with her in "Poor Little Rich Girl". He is recognized by someone as "Jack", but dismisses it as a mistake to Fallon. After he helps her try to manipulate a confession out of her mother Alexis (Nicollette Sheridan) in "Don't Con a Con Artist", Liam and Fallon kiss. Fallon agrees to a date with him in "Use or Be Used", but misses it when she learns that her ex-boyfriend Michael's father is in the hospital. Alexis reveals to Fallon that Liam is really a journalist named Jack Lowden writing a tell-all, and Fallon cuts him loose. Liam gives Alexis his manuscript—actually about his own wealthy family—for delivery to Fallon, but Alexis burns it instead. Liam appears at Steven and Sam's wedding in "Dead Scratch", and tells Fallon he is in love with her. He reveals that his manuscript was about his own family, the Van Kirks of New York.

In "Twenty-Three Skidoo", Fallon is negotiating to sell Carrington Atlantic to Liam's uncle Max Van Kirk (C. Thomas Howell), but she and Liam have to pretend to still be married to secure the deal. Max coerces Fallon and Liam to kiss in front of him, which leaves Fallon slightly confused about her feelings. Liam introduces Fallon to his imperious mother, Laura (Sharon Lawrence), in "The Butler Did It", and Fallon faces off with her in Liam's defense. Suspecting Michael (Robert Christopher Riley) is cheating on her, Fallon almost has sex with Liam in "Queen of Cups". Liam gives Fallon an ultimatum about their relationship in "That Witch", and she ultimately chooses Michael over Liam. In "A Champagne Mood", Fallon and Michael go to Liam for his help in accessing Van Kirk files, which they hope will prove that Max was behind the drug smuggling and keep Michael out of jail. Although reluctant at first, Liam agrees to help. After Fallon breaks things off with Michael because she cannot trust him, she visits Liam, but another woman answers the door. In "The Sight of You", Fallon takes a girls trip with Monica (Wakeema Hollis), Cristal (Ana Brenda Contreras), and stowaway Kirby (Maddison Brown), but her true motive is to see Liam, who is at the same ski resort in Idaho with his new girlfriend Ashley (Taylor Black). While Sam and the women sabotage Ashley, Fallon asks Liam for another chance. He is happy with Ashley, and asks Fallon to move on as well. After Ashley and her friends brawl with Fallon and her posse at a dive bar, a furious Liam tells Fallon he never wants to see her again. In "Miserably Ungrateful Men", Fallon buys the publishing company that is releasing Liam's novel, intending to scrap the book but trying to manipulate him into pulling out of the deal on his own. In "How Two-Faced Can You Get", Fallon reads and loves Liam's novel, which is about their relationship. She goes to him to apologize, and offers to publish it after all. In "Life is a Masquerade Party", Fallon arranges for Liam and his ex, Ashley, to spend time together in public to promote his book, but is jealous when they appear to be rekindling their relationship. Fallon and Liam admit they are in love with each other. Fallon's brother Adam (Sam Underwood) takes a photo of Fallon and Liam kissing, which he sells to the press. The negative publicity surrounding the photo threatens Liam's book sales in "This Illness of Mine", forcing Fallon to confirm publicly that the book is about her and not Ashley. Liam's mother Laura appears and threatens to block the novel's publication unless Fallon breaks things off with Liam. He tries to broker a peace over dinner. Laura claims to be dying of cancer, but Fallon is suspicious. Fallon has Laura's blood tested and proves she is lying, but Laura deflects the accusation and Liam is angry with Fallon. Laura is eventually forced to confess, and Liam softens to Fallon. In "New Lady in Town", Fallon and Liam plot to expose Adam's true colors to her father Blake (Grant Show), but Adam outmaneuvers them each time. While Fallon steps in for Blake to prevent Jeff and Michael from seizing control of the Atlantix in "Thicker Than Money", Liam and Kirby help her snatch a book deal from a competitor. Liam and Fallon finally have sex. Liam, hit over the head by Adam, falls face down into the pool in "Deception, Jealousy, and Lies".

In "Guilt Trip to Alaska", Liam has been rescued but lies in a coma. Adam tries to kill Liam in the hospital, but is interrupted by Fallon. Ashley arrives, and when Liam wakes up, he does not remember Fallon. She pulls out all the stops to get Liam to remember her in "Caution Never Won a War", but his mother Laura does her best to thwart Fallon's efforts, including filing a restraining order against Fallon. Learning that Liam is marrying Ashley, Fallon attempts to restore Liam's memory in "Something Desperate" by having him read his original manuscript that details their relationship. He reads it and does not marry Ashley, but tells Fallon he still does not remember her, and wants to be on his own. Just as Fallon moves on from Liam with Evan (Ken Kirby) in "Mother? I'm at La Mirage", Liam begins to remember their past together. He asks her to dinner, hoping to recover more memories, in "A Used Up Memory". Not wanting Liam to remember what Adam did to him, Adam arranges for Evan to see Fallon with Liam. A possessive Evan warns Liam to keep away from Fallon. Liam's memories return, and he and Fallon reunite. In "Shoot from the Hip", Fallon is worried that Liam will forget her again, and he is angry to discover she lied to him to keep him close. Fallon gives Liam free rein in writing an article about Blake's murder trial for her magazine in "The Sensational Blake Carrington Trial", but when he includes her own less-than-flattering courtroom performance, she trashes her own office and erases the article. Fallon realizes that Adam's sight has returned, and Liam remembers that it was Adam who hit him over the head. In the vineyard's barn, they struggle at the edge of the loft door. In "The Caviar, I Trust, Is Not Burned", Adam saves Liam from falling but then falls himself. Liam and Fallon fight and then reconcile when Fallon begins making life decisions without consulting him in "Battle Lines".
