Danielle (Castle)

Danielle (Amy Gumenick) is the main villainess from "The Mistress Always Spanks Twice," episode 2.16 of Castle (airdate March 8, 2010). She is the roommate and best friend of Jessica Margolis, who was found dead at a jungle gym.
Danielle spoke fondly of Jessica, as they had been roommates since their freshman year of college. She considered Jessica a sister to her, but as later revealed, Jessica began working as a dominatrix, going by the name Mistress Venom. Her work was part of a project she was conducting, which included writing a thesis about her clients. Among her many subjects was Danielle, who Jessica referred to as being dangerously co-dependent on her. Danielle read Jessica's thesis when fellow student Matt Haley left the files at their apartment, and upon reading it, she became furious.
Danielle confronted Jessica, who stated that she was going to move in with her boyfriend, Tyler Benton. The confrontation became violent when Danielle shoved Jessica, and in response to Jessica's lashing out, the deranged Danielle smothered her friend to death. After the murder, Danielle dumped Jessica's body at the jungle gym and covered her in caramel to avert suspicion; making it look like a sex act gone wrong. Her plan worked at first, as dominatrix Lady Irena became suspected of the murder. 
However, Richard Castle figured out that Danielle was the killer when it was uncovered that while the pillow had saliva, the case didn't, meaning that Danielle washed it along with the rest of the laundry. Castle and Kate Beckett confronted the villainess, who revealed her clingy personality and confessed to everything, claiming she didn't mean to kill Jessica and that she was hurt by her friend's cruel words. Beckett looked at her in astonishment, while Castle looked at her sadly. Following her confession, Danielle was arrested (off-screen).
