Kim was arrested for assaulting Slice and outwitting Anton when she was a commercial sex worker. As per the report, it led the man to rape a woman named Alessandra. Also, Kim fooled her sister into murdering her former boyfriend Jeff. She did it by setting up the latter as if he was trying to assault her sexually while she was pregnant.

In other news, series actor Peter Scanavino revealed that his character Carisi is set to remain as a police officer. In his interview with E!Online, Scavino said that Carisi was going to stay a police officer, since he had taken an oath to serve and protect, which he thought he really believed.

"It would seem unfinished for him to leave, that he hasn't done everything he wanted to do in this part of his life yet, so I think he's going to continue that," Scanavino said.

Along with victim's secret, the promo trailer for the episode also unveils more of her work in the prostitution industry. But then, the case may not be on her side if things become publicized.
