• In 2022, the actress who portrayed Pam, Alley Mills, decided to leave the show and pursue a new role in "General Hospital." This transition led to a reduced presence in The Bold and the Beautiful.
• Pam was devastated when Stephanie passed away, and Eric asked her to stay in town with them as she was part of the family. She continued working.
• After making amends with her mother, Ann, and dealing with the grief of her sister Stephanies death, Pam has taken a backseat to the drama.
• Pam and Charlies relationship may be coming to an end, as Charlie appears to have found a new love interest.
• Once Charlie pushed past the flirting to make an actual move at the end of the fashion show, it seems pretty clear that he and Pam are over.
