Rebecca Shaw (General Hospital) - Kristina Cassadine

Kristina Cassadine (previously Carter) is a fictional character on the ABC soap opera, General Hospital. She was portrayed by Jamie Ray Newman from 2001 until 2003. Kristina is the daughter of Mikkos Cassadine and opera singer Kristin Bergman, and the sister of Alexis Davis. When her mother was killed by Helena Cassadine, Mikkos' wife, her father fostered her with the Carter family to protect her.

As an adult, Kristina hires Angel Sorel Ellis to find her sister, Alexis. Ellis also works for Jasper Jacks (Jax), who reveals to Alexis in 2001 that her sister is alive. As they are about to meet Kristina, Jax and Alexis find Chloe Morgan dead. Alexis steps in to act as Stefan Cassadine's lawyer, who had been arrested for Chloe's murder. Meanwhile, Kristina meets Ned Ashton while at Luke's Club, and the two flirt. They go to the Police Department when they hear about Chloe, where Kristina tries to meet Alexis but Alexis is too distraught. Kristina later overhears Alexis tell Jax that their meeting should wait, but instead Kristina introduces herself and they hug. Alexis later tells Kristina the truth about how she was lost as a child.

Kristina later changes her name from Carter to Cassadine and decides to stay in Port Charles and live with Alexis. She works as Ned's assistant at L&B Records and they get engaged. Alexis later becomes pregnant with Sonny Corinthos' child, and Ned steps in as the father in an attempt to keep the baby away from Sonny's dangerous business. Believing Ned and Alexis had slept together, Kristina decides to leave town, but Alexis convinces her to stay. Kristina finds a letter proving Sonny is the father of Alexis' baby, and arranges to meet him at his warehouse. There she is caught in an explosion set by Luis Alcazar and is injured. At the hospital, Alexis begs her not to say anything, and she agrees.

Kristina dies in August 2002, and Alexis names her daughter Kristina Davis in memory of her sister. After baby Kristina is born, adult Kristina appears in a dream to Alexis. Days later, Luis Alcazar is pushed from his balcony and the killer is eventually revealed to be Alexis. Alexis fakes dissociative identity disorder, saying her other personality was Kristina, and is able to avoid murder charges.
