One of her most memorable storylines began in 1995, when her teenage character contracted HIV after having unprotected sex with her boyfriend Stone, who was unknowingly infected with the virus and later died of AIDS.
On General Hospital, Robin Scorpio was also written out for the same reason, except the character was attending Yale University to study medicine.
In 1998, she returned to the show, but then left once again to pursue other acting opportunities, which included co-starring in the primetime drama series Once and Again and Joan of Arcadia.
She also wrote and directed the mockumentary Lil Star about girls in childhood beauty pageants, a story which allowed McCullough to draw on her own experiences.
In November 2011, McCullough announced her plans to leave General Hospital once again in order to pursue a career as a director, and her character was believed to have died on February 21, 2012.
However, scenes airing on March 27, 2012, showed Robin to be alive and held captive in an undisclosed location, leaving the door open for her to return in the future.
[5] McCullough did make an appearance in 2021 to participate in an on-air tribute for actor John Reilly, who played Sean Donely.
