In May 2014, newcomer Michelle Stafford revealed that she had taped scenes opposite Kristen indicating that the actress would reprise her role of Delia.

In 2023, when asked if she would return to General Hospital as Delia, Kristen replied:

"It would be nice if Delia lived for real. It's like Delia in people's imaginations. We'll see. I'm sure I will be making some kind of appearance on that show at some point. It's too bad, because Delia could be causing a lot of trouble. They never exploited it for what it was worth."
