Villainous kidnapper Alice
Alice (Victoria Blade) is the main villainess from "The Devil You Know," the penultimate episode of Blue Bloods' eighth season (airdate May 4, 2018).
Alice's backstory revealed that two years prior to the events, she was once pregnant, but her baby was stillborn. In the time that passed, Alice returned to the same hospital where she lost her baby, doing so several times under the pretense of being pregnant, only for her deception to be uncovered. The episode's events saw Alice return dressed as a nurse and approach patient Sofia regarding her newborn daughter, only for Alice to abduct her.
The opening saw officers Eddie Janko and Jamie Reagan arrive the hospital, where Sofia's father engaged in a fight with Jorge, Sofia's boyfriend and the father of her daughter. It was at this point that Sofia informed the pair what occurred: a woman calling herself a nurse took her baby under the pretense of wanting to hold her and check on her. The investigation led the officers to a shop where the proprietor stated that she was looking to buy diapers and formula for the baby, only able to afford the latter.
Jamie and Eddie retrieved surveillance video and found the abductor, who a nurse identified as Alice. She was spotted running from her apartment once the pair arrived, and they encountered her again in the episode's climax. The deranged villainess later stood on a ledge and threatened to drop the baby if the police didn't back away, and in response to Eddie's pleas, the evil Alice remained insistent that the baby was hers. Even so, Eddie managed to talk Alice down off the ledge, and Alice was arrested after the baby was saved.
