Calista's (Jennifer Esposito) lies will finally catch up with her in the upcoming episode of ABC's sexy mystery drama "Mistresses."

In "Guilt by Association," TV Guide reports that the boutique owner will find herself in trouble, as the police will secure evidence, which puts her in the crime scene. Instead of helping Joss (Jes Macallan), however, the cops now think that the two conspired to kill Luca (Noam Jenkins) together.

According to the International Business Times, Joss' lawyer, David (Corey Sevier) will keep his word to prove his client's innocence. Daniel (Ricky Whittle) has given him strong proof that can incriminate Calista — a tape containing surveillance from the neighbor's camera.

In the footage, a car can be seen driving away from the murder scene. Even though it does not show the suspect's face, the cops immediately pounced on what is evident — the driver is wearing a wedding band that looks suspiciously like Calista's. In the show's promo, the fashion designer looks flabbergasted, claiming that she is not the person in the getaway car. The police, however, are not convinced.

Also in episode 11, April (Rochelle Aytes) and Blair (Brian White) will face some problems in their relationship. The former is battling with her guilt after cheating on her boyfriend with Daniel. With no one to turn to, she will seek comfort from her own daughter. It looks like her romance troubles will give her the chance to be closer to Lucy (Corinne Massiah), whom she has been struggling to connect with in the past episodes.

Meanwhile, Karen (Yunjin Kim) will finally tell Alec (Ed Quinn) and Vivian (Sonja Bennett) about the baby. While truly shocked, the couple will surprise the expecting mother with a proposal — that they raise the child together in "a modern kind of family." Can their situation get any complicated than this?

"Mistresses" airs Thursday at 9 p.m. EST on ABC.
