The character Paul Williams was born in May 1960, the son of police detective Carl Williams (Brett Hadley) and
Mary Williams (
Carolyn Conwell). He has three siblings: Todd, Steven and
Patty. Paul begins dating close friend,
Nikki Reed (
Melody Thomas Scott), giving her a sexually transmitted disease. The romance ends when she takes up with
Greg Foster (
Wings Hauser); Paul begins dating
April Stevens (Cynthia Eilbacher), who gives birth to his daughter
Heather (
Eden Riegel) despite his desire for her to terminate the pregnancy. He leaves town with Nikki to join a cult, the New World Commune. Paul's brother, Steven, helps to save them from the cult and rescues the former lovers. While Paul and Nikki are away, Greg dates April. However, April falls ill and Greg convinces Paul to marry her. The ill-conceived marriage ends in divorce; Paul focuses on his detective career, unsuccessfully trying to find his mentally unstable sister Patty (
Stacy Haiduk). While Paul and business partner
Andy Richards (
Steven Ford) work undercover to infiltrate organized crime, he dates prostitute Cindy Lake. Cindy takes a bullet for Paul, dying in his arms. His mother opposes his relationship with Cindy, and also disapproves Paul's marriage to
Lauren Fenmore (
Tracey Bregman). Their union suffers when she is stalked by
Shawn Garrett (
Grant Cramer), who convinces Paul that Shawn and Lauren had an affair. The marriage ends, although Paul comes to her rescue when Lauren is kidnapped and buried alive by Shawn. Pregnant, Lauren has a miscarriage. She and Paul reconcile, although when Lauren submits a nude photo of Paul for a magazine centerfold they break up permanently. Paul becomes involved with his friend George Rawlins' (Jonathon Farwell) wife Cassandra (
Nina Arvesen), unaware of the marriage. Cassandra's announcement that she is filing for divorce causes George to have a heart attack, and he becomes terminally ill. He learns about the affair, planning to kill himself and frame Paul for his murder. Paul fakes his own suicide and goes into hiding; he, his father and
Victor Newman (
Eric Braeden) work to clear Paul's name. George's killer is Adrian, Cassandra's lover from Bermuda. She marries
Brad Carlton (
Don Diamont), who leaves her after learning that she drugged him. Cassandra tries to reconcile with Paul, but she dies in a car crash. After dating his secretary
Lynne Bassett (
Laura Bryan Birn), Paul falls in love with his partner
Christine Blair (
Lauralee Bell). After his mother declares his father Carl dead, Christine discovers that he is an amnesiac living in Norfolk. She brings Carl to town to see Paul, although he remembers little. Despite Mary wanting him back, Carl does not remember anything and returns to Norfolk. After Christine's marriage to
Danny Romalotti (
Michael Damian) ends, Paul and Christine begin a relationship. April, married to Robert Lynch, returns to town with Paul's daughter Heather. Lynch abuses April, and she stabs him. She is arrested, and Christine is her legal representative. April is acquitted, and returns to New York with Heather. Christine still loves Danny; his mistress
Phyllis Summers (
Michelle Stafford) faked her son
Daniel Romalotti's (
Michael Graziadei) paternity, and he is not Danny's biological child. However, Christine and Paul continue their wedding plans. A crazed Phyllis believes that Christine will try to reconcile with Danny. The night before the wedding Phyllis crashes her car into Christine and Paul, postponing the marriage. Christine and Danny briefly reconcile before she returns to Paul, whom she marries shortly thereafter. She begins a law practice with
Michael Baldwin (
Christian LeBlanc), who try to rape her years ago, which requires her to spend months out of town working on cases in Hong Kong and Australia. Paul begins an affair with a client,
Isabella Braña (
Eva Longoria), who previously dated Michael. Christine finds out and divorces Paul after a six-year marriage. Isabella becomes pregnant; she does not tell Paul because of his feelings for Christine, telling Michael that he is the father. She and Michael begin a relationship, and reconciles with his ex-wife Lauren. When Paul learns about Isabella's baby he moves in with her, and they eventually marry despite Mary's opposition. She gives birth to their son,
Ricky Williams (Peter Porte). However, when Christine and Michael become engaged Paul recognizes his feelings for her and wants to reconcile. He assaults her sexually, and she leaves town. Christine returns in disguise, and works with Mary to expose Isabella as manipulative and scheming. Christine and Michael's engagement ends when he tells her he set up Isabella and Paul so he could have Christine for himself, and she and Paul reconcile. An unstable Isabella tries to frame Christine for her own murder, and later tries to drown Christine in her bathtub. Paul rescues Christine, Isabella is institutionalized and Ricky is sent to live with her parents. Paul and Christine's relationship again ends. Paul closes his investigative company and begins a partnership with Christine, hiring fledgling PI
J.T. Hellstrom (
Thad Luckinbill) as an apprentice. He continues detective work, rescuing J.T. and
Sharon Newman (
Sharon Case) when they are kidnapped by the attempted murderers of Brad's family decades earlier (when he was known by his birth name, George Kaplan). Paul investigates Lauren's enemy
Sheila Carter (
Kimberlin Brown), who had plastic surgery to look like Phyllis (Lauren's best friend) and scheme her way into Lauren's life. Paul captures Sheila, locking her in a warehouse cage, and begins dating detective
Maggie Sullivan (
Tammy Lauren). Sheila escapes, shoots Maggie (leaving her locked in the cage with Paul) and goes on a rampage, kidnapping Lauren, Phyllis and their children until she is shot and killed by Lauren. Maggie agrees not to tell the authorities about Paul (and eventually Michael), keeping Sheila trapped. Paul's daughter Heather (
Vail Bloom) returns to Genoa City as an assistant district attorney, and develops a relationship with her father. He reconciles with first love Nikki, and they become engaged. She then breaks up with Paul, unable to move past her feelings for ex-husband Victor. Paul investigates a businesswoman, Mary Jane Benson, only to discover that she is his unstable sister Patty. Patty goes on a crime spree, poisoning Nikki and Victor's granddaughter
Summer Newman (
Haley King), kidnapping
Colleen Carlton (
Tammin Sursok)—who eventually drowns—and shooting Victor three times before escaping. Paul tracks down Nikki, and brings her back to town to help Victor recover. Patty is found and sent to a mental institution, where Paul visits her regularly. He begins dating Christine's former best friend,
Nina Webster (
Tricia Cast). A love triangle forms between Paul, Nina and Christine when the latter briefly returns to Genoa City, and Paul helps Nina track down her long-lost son
Ronan Malloy (
Jeff Branson). Paul's son Ricky (now an adult) returns to Genoa City, working for attorney
Avery Bailey Clark (
Jessica Collins). Paul attempts to bond with Ricky, but soon discovers that Ricky is psychotic like Isabella. Paul is forced to shoot and kill Ricky to keep him from killing
Eden Baldwin (
Jessica Heap). Before dying, Ricky confesses that he murdered his ex-girlfriend Rachel when she dumped him. Paul surrenders to the police, and is shocked when no knife (with which Ricky threatened Eden) is found at the scene and Eden has no memory of the event. Christine returns to town, and with her and Heather's help Paul is acquitted. Months later he becomes the Genoa City police chief, remaining involved in a number of legal cases. Eleven years after their divorce, Christine and Paul remarry at their friend
Katherine Chancellor's (
Jeanne Cooper) funeral, with Paul following Katherine's advice in a letter he received during the ceremony. ==Character development==
