Pam Douglas and her sister, Stephanie, were raised by John and Ann Douglas in a suburb of Chicago. Stephanie married Eric Forrester and moved to Los Angeles, rarely mentioning her sister and telling her everyone that her parents were dead. In reality, John had abused Stephanie as a child, which Ann had ignored. When Stephanie's controlling behavior got out hand, she sought therapy with Taylor Hayes, who suggested that Stephanie go to Chicago and confront Ann. With Eric at her side, Stephanie found Pam taking care of widowed Ann, who was still in denial. Mousy Pam finally spoke up and confirmed the abuse, admitting she was too scared as a child to help her older sister.Stephanie remained at odds with her family until Eric invited Pam and Ann to Los Angeles for Christmas. After Ann returned to Chicago, Pam stayed on in the Forrester guest house and took a shine to Eric, actively discouraging Jackie Marone's interest. But Pam, who had a long-held resentment about Stephanie living the high life while Pam was stuck caring for their mother, started showing signs of instablity. When Pam went off her medication for bipolar disorder, Ann feared that Pam had shot Stephanie, although Storm Logan had pulled the trigger. Stephanie's marriage to Eric crumbled, and Eric moved on with Donna Logan. Pam trapped Donna in a tanning bed and turned Donna's hair and teeth green. Pam also replaced Eric's Viagra with sleeping pills. But Pam's pranks got more serious when Pam intimidated Donna with "Tiny", her giant Doberman, and threatened to kill Donna on several occasions. Eric and Stephanie blew off Donna's concerns about Pam. "Tiny" died after eating a lemon bar Donna threw to distract him. Finding out that the dog actually died from a reduced dose of heart medication did nothing to quell Pam's hatred of Donna.
After Donna and Eric were married, Eric had a heart attack in bed and slipped into a coma. Donna, who had been eyeing Owen Knight, was accused of spiking a bottle of gin. But Eric had actually fallen ill after Pam fed him a laced lemon bar, only hoping to weaken him and make him sexually undesirable to Donna so Eric would go back to Stephanie. Pam lured Donna to the Big Bear cabin, where she held Donna at gunpoint, doused her with honey, and let a bear in to attack her. Pam ran off after Owen saved Donna.
A crate arrived for Donna at Forrester, but her son, Marcus Walton, opened it and was bitten by a snake. Soon after, Donna's mother, Beth Logan, was hit by a car. Pam returned and promised to kill Donna's family, and even Eric, if Donna didn't leave Eric. Donna complied, but confided in Owen, who told Eric and Stephanie. Together, they coaxed Pam out of hiding by lying that Ann was deathly ill. Stephanie gently got Pam to admit that she did everything to make up for not protecting Stephanie from their father. It was revealed that Pam had developed a mass of scar tissue on her brain after falling down the stairs running from her father as a girl. Donna scoffed that a tumor couldn't have made Pam violent, but after an operation, Pam had no memory of what she'd done, and tried to make amends with Donna before being transferred to a facility in Chicago.
Pam returned for follow-ups in Los Angeles and was hired to design bikinis for Forrester's new surf line. But Pam was jailed on suspicion of blowing up Rick Forrester's car and setting fire to his house. (The real culprit was Thomas Forrester.) Pam's fascination with the game show The Price Is Right led her to make a clerical error on Ridge Forrester's marriage license, invalidating his marriage to Brooke Logan. Later, Pam and Donna ended up on The Price Is Right together and actually enjoyed themselves. But when Donna modeled the Royalty line's showstopper, Pam couldn't resist dumping gallons of honey on Donna.
Pam left Forrester and joined Stephanie, who had defected to Jackie M. Jackie befriended Pam, who fit in with Jackie M's "band of misfits." Later, Pam supported Stephanie through a mini-stroke, and found brief fame co-hosting fashion talk show The Catwalk with Donna, amusing audiences with her "cat dance." Ann made a mysterious trip from Chicago and announced she was dying. Stephanie and Pam butted heads when Pam took Ann to a hospital against Ann's wishes, so the Douglas sisters snuck in and broke Ann out of her room. Pam and Ann had a chance to resolve their issues before Ann died peacefully at Paradise Cove.
Pam returned to Forrester Creations with Stephanie and found an anti-Logan ally in Steffy Forrester. Together, they sabotaged Hope Logan's Hope For the Future showing, rigging the sign to read "HO" For the Future. Donna's father, Stephen Logan, blamed Stephanie for her inadvertent part in the drowning death of his wife, Beth Logan, so Stephen romanced and deflowered the naive Pam, convincing her to stop taking her bipolar medication. Stephanie objected to Pam dating Stephen and dragged Pam to the Big Bear cabin. Stephen arrived and put a gun in Pam's hand, reminding Pam how much she resented Stephanie. Pam nearly shot Stephanie, but backed off, apologizing to Stephen for trying to kill Donna at that very cabin and asking Stephanie what "those poor Logan girls" had ever done to deserve Stephanie's hatred. Stephanie got the gun from Pam and shot Stephen, who later insisted his feelings for Pam were real. Pam and Stephen were soon engaged, and even made wedding plans.
Months later, Stephen inexplicably ditched Pam and ran off to Texas. Pam cited Stephanie's lack of support, but the same day, Pam surprised Jackie's son, Nick Marone, in the Jackie M steam room. With Jackie M in financial trouble, Jackie convinced Pam to steal Forrester designs, promising Nick would return the favor with romance. Nick grimaced at first, but developed a genuine bond with Pam. After the Forresters saw their designs on Jackie M's runway and blamed Beverly, a new intern, Pam wanted to turn herself in.
Pam put itching powder in Donna's nightie when Nick showed an interest in Donna. Pam roped Nick into appearing on Let's Make A Deal, and when Donna saw them together on the show, she realized Pam had stolen the designs and went straight to Stephanie. Pam confessed and was fired from her receptionist job. But after Stephanie forgave Pam and rehired her at the same time Brooke hired Donna for the position, Pam and Donna were forced to share receptionist duties, and a desk.
Pam was devastated when Stephanie, who had been battling cancer, received a terminal diagnosis. Stephanie tried to assure Pam by hinting that Pam would be taken care of, but when Pam asked for clarification, Stephanie only said, "you'll see." After Stephanie died, Pam felt she should return to Chicago, but Eric claimed her as family and asked her to stay in Los Angeles. Pam doted on Eric, and the two found they were both avoiding actively grieving Stephanie. Pam was somewhat amused to discover that Donna was also offering support to Eric. But Pam and Donna uncharacteristically found themselves on the same page when they were dubious about the attention Taylor was starting to show Eric.
When Eric and Taylor officially got together, Pam stabbed a magazine photo of Taylor and confronted the duo in their bedroom brandishing a knife. Taylor screamed, but Pam laughed and showed her she was only holding up a spatula. Pam seemed to accept the relationship, but Eric and Taylor were concerned about Pam's bizarre behavior.
Pam's duties at Forrester included maintaining the Forrester web site, and a search for young Caroline Spencer yielded a photo of Caroline caressing a porn star. Pam was taken aback when Caroline demanded that Pam "fix the Internet." Later, Pam carelessly blabbed to Lt. Baker about a car that had been towed for Brooke, who was trying to cover up a drunk driving accident involving Bill Spencer. Pam also blurted out to Taylor that Brooke was in conference with Lt. Baker, prompting Taylor to listen at the door and ultimately accuse Brooke of sleeping with Bill. When Brooke hedged about modeling lingerie from the rebooted Brooke's Bedroom line, Pam donned some of it for Eric and Taylor to show that age was no reason to stop being sexy.
Later, Pam and Donna disagreed over whether Rick should be with his new girlfriend, Maya Avant, or Caroline Spencer, his ex-girlfriend. But when Pam suggested that Maya wear Forrester fashions in her new web series, Room 8, Rick took Pam seriously and went to talk to the show's advertisers, which pleased Pam. As Forrester Creations embarked on a collaboration with Quinn Artisan Jewelers, Pam traded in her usual pearl necklace for one of the new line's creations, gushing to the designer, Quinn Fuller, what a fan she had become of the collection.
Forrester's collaboration with Quinn Artisan Jewelers led to the loan of a priceless blue diamond for the rebranded HFTF line, which was being protected by Charlie, a quirky security guard. Pam found that she and Charlie had much in common, especially baking and cooking, and they prepared the Forrester Thanksgiving meal together, with Charlie admitting he wanted to spend a lot more time with her. When Hope declared that everyone had to say something nice about their seatmate, Pam told Donna she was the most annoying person she'd ever met, but that she was her best friend.
Pam gained another friend when she and Quinn began to spend time together, but Pam was hurt when she found out that Quinn was only cozying up to her as a means to control Charlie, who discovered the jewel thieves that had been accused of trying to steal the HFTF diamond were innocent; in reality, Quinn's son, Wyatt Fuller, had pocketed the gem to make himself look like a hero to Hope and then planted the diamond on the thieves. After Quinn threatened Charlie into keeping the security footage to himself, he and Pam showed it to Hope's ex-boyfriend, Liam Spencer, who was out to prove that the Fullers were not what they claimed to be. When Eric's granddaughter, Aly Forrester, likewise had ill feelings about Wyatt and Quinn, Pam told the girl to trust her instincts. But Aly had some mental issues resulting from the fact that Taylor had accidentally killed Aly's mother, Darla Einstein, when Aly was a child, and Pam, having dealt with her own such issues, sympathized with Aly and shared Eric's concern about Aly's growing rage.
Pam began attending medieval-themed events with Charlie, and left an axe in the Forrester photo studio, which Aly later used to threaten Taylor. Then, Ridge was presumed dead after falling out of a helicopter over the Persian Gulf; when Pam found out that Ridge had gone to stop Brooke's wedding to Bill only after Quinn showed Ridge a photo of herself in bed with Bill, Pam insisted that Quinn was the devil, which helped lead to Forrester terminating its contract with Quinn Artisan. Later, Pam and Charlie took Aly and her boyfriend, Oliver Jones, to one of their Renaissance outings at dinner theatre Medieval Times.
When Aly found out that Oliver had only initially shown an interest in her because of her status as a Forrester, Pam consoled Aly and wanted to believe Oliver's claim that he had developed real feelings for the girl. Pam and Charlie took a distraught Aly to role-playing dinner theatre Medieval Times, where they were all shocked to see that Oliver had taken the place of a jousting knight to prove his love for Aly. Later, Pam, Charlie, Oliver and Aly worked on a medieval story together. Pam continued working at Forrester, dating Charlie, and offering her lemon bars to fashion show attendees, including Gloria Baldwin of Genoa City.
Pam was surprised when Eric's brother, John Forrester, came for a visit, but more so when he flirted with her and suggested she market her baked goods, which rankled Charlie. At Christmastime, Pam went to the Forrester Sky Lounge and found John there with a selection of dogs for her; although Pam still missed "Tiny," who had died years before, she wasn't ready to adopt a new friend yet. However, Pam let John know she appreciated the gesture.
Eric stepped down as CEO and named Rick as his successor. But Rick, who was furious with his estranged wife, Caroline, for kissing Ridge, took Maya as a mistress, moved her into the Forrester mansion, and replaced the departed Stephanie's portrait with one of Maya. Pam took a hostile Rick to task for disrespecting her sister, but began walking on eggshells, along with her fellow Forrester employees, as Rick became more and more rageful. Pam hoped Eric would reign Rick in after Rick fired a gun at Ridge and Caroline, but when Eric was impressed with the sales numbers under Rick's tenure instead, Pam joined her fellow Forrester employees in an attempt to convince Eric otherwise. As a soon-to-be-divorced Caroline explored a relationship with Ridge, Pam joined Donna in warning Caroline that Ridge always went back to Brooke eventually.
Pam overheard Liam and Wyatt discussing their desire to unearth a secret about Maya and offered to help since the secret could end Rick's tenure as Forrester's CEO. Pam recruited Charlie and snooped through Rick's office, finding Maya's purse. When Pam found a prescription for estrogen, she was shocked by Charlie's announcement that the only reason Maya would take the hormone is that she's transgender. Pam decided the secret should be kept and played it off when Rick caught her and Charlie in his office without permission.
After Ridge, his children, and Liam gathered together enough stock to boot Rick as CEO, and Maya's gender identity became public knowledge, Pam marveled at the showing of Forrester's California Freedom line, which featured transgender models. Later, Pam was devastated when Aly, who had regressed, died in an confrontation with Steffy; Pam consoled the heartbroken Oliver. Later, it was revealed that Pam was taking medication for anxiety.
