Kristina Curtis was a villainess from "Once Upon a Crime," episode 4.17 of Castle (airdate February 27, 2012). She managed her family's art gallery.
On May 6, 2005, Kristina was at a fairy tale-themed rave with friends Amy Morgan and Charlotte Boyd, with Kristina dressing as Snow White. Owen Thomas, who was dressed as Prince Charming at the rave, got extremely high on drugs and started behaving erratically when he got out of Amy's car while under the influence. In response, Charlotte accidentally ran over and killed Owen while driving away. Following the accident, she paid for the damages to Amy's car. In addition, Kristina agreed to cover up the accident, part of a pact she made with Charlotte and Amy.
Nearly seven years later, all three women were blackmailed by a mysterious person, later revealed as Darren Thomas (Owen's brother), who demanded a lump sum of $50,605 from each of them. Kristina paid off Darren to continue covering for herself and her cohorts, but was unaware that Charlotte had killed Amy afterwards out of fear that her crime could still be revealed. Kristina was also a fatal victim of Charlotte's heel turn, as she was ambushed and killed by her villainous co-conspirator with a drug cocktail while out jogging in Central Park. Kristina was left dressed in her Snow White costume with an apple in her hand and text from the original Grimm fairytale etched into her skin.
