Misha Vanni, aka Chloe Wilson (Aly Michalka), was a villainess from "In Plain Sight," episode 4.10 of Motive (airdate July 26, 2016). She was introduced as the long lost daughter of Ava Wilson, and the younger sister of Jessica Wilson.
Chloe's backstory revealed that she was abducted 20 years ago by Ava's estranged husband, Jeremy Sheridan, who attempted to take both girls. Chloe was three at the time of the abduction, and it was private investigator Ian Mitchell who brought Chloe back to Ava and Jessica. However, in a twist, the actual Chloe Wilson was killed in a car accident in Mexico seven years prior to the events, along with Jeremy, and the woman posing as Chloe was a prostitute named Misha Vanni. Misha colluded with Ian to pose as Chloe to obtain Ava's wealth, as Ava was dying of a terminal disease.
The villainess and her cohort figured it would be quick and that Ava would pass on soon after the reunion, but Ava managed to live on for several more months with her illness. All the while, the evil Misha continued to pose as Chloe, while also forming a relationship with a man named Cam. However, Ava had been suspicious of her daughter's true identity, and it was Misha's response to Ava's question about her vaccinations that gave her away, as Ava stated that while Jeremy was deranged, he put the health of the girls above anything else. Now exposed, Misha was set on moving out, but to her surprise, Ava kept Misha around and paid her to help end her life, as she wanted to die with dignity and also wanted Jessica (who had been taking care of Ava for so long) to have a life of her own.
Jessica had no idea about Misha/Chloe's true identity, but she did find out that Misha had bought an oxygen tank and had looked up ways to kill someone. Jessica confronted the greedy villainess at her renovated house regarding her plan to kill Ava, with Misha responding that Ava wanted to die. Jessica later fought with the woman she thought was her sister, picking up a nail gun and firing four nails at her. The last two pierced Misha's chest, killing her instantly.
