CAT INVESTIGATES THE MURDER OF A BALLERINA — When a rising young ballerina mysteriously falls to her death, Vincent (Jay Ryan) senses that the understudy, Victoria (Elizabeth Blackmore), is hiding information about the dancer’s murder. Cat (Kristin Kreuk) and Tess (Nina Lisandrello) discover that the victim tried to file a police report for an assault. Meanwhile, Cat seeks out Vincent’s help to decipher a medical paper found in her mother’s belongings, and J.T. (Austin Basis) worries that Cat’s visits to the warehouse loft leave Vincent vulnerable to discovery by Muirfield’s agents. Catherine encourages Vincent to help her investigate deeper into the Muirfield project, but when Vincent refuses, Cat investigates on her own, until her computer is wiped clean by a malicious virus. Tess tries her hand at dating again, but soon discovers that she’s unknowingly involved with a married man. Heather (Nicole Gale Anderson) moves out of Cat’s apartment after growing uncomfortable with her sister’s quest for more answers about their mother’s death. Rick Bota directed the episode written by Sherri Cooper & Jennifer Levin.
