“Antifreeze”

No one is interested in Mary’s strange overnight stay in the park, as Ryan is feted as one of Gotham’s young business leaders. As she meets Marquis there, Sophie’s sister Jordan disappears, and when Marquis helps them find her, she has been frozen somehow at room temperature. Alice persuades Montoya to let her out again after Mary speculates that her hallucinations may come from drugs given to her at Arkham. Alice determines that the Black Glove has been illegally experimenting with safely freezing people; Jordan was targeted because she was investigating them. Mary is able to save Jordan with her newfound botany by thawing her from the inside. Jada leaks to Vesper that Wayne funds have been diverted into a black budget (in fact the Batcave’s). As the stock tanks, Luke and Wayne PR employee Charlie are able to sell the diversion as a classified defense project for A.R.G.U.S. with help from John Diggle, but the board of directors ask for Ryan to resign as acting CEO, since Wayne risks a hostile takeover should she not.

Batwoman picks up Alice from Sophie’s apartment to look at a man strangled with a bullwhip. Renee thinks it might be Catwoman’s — it isn’t, but Alice reviews old files with Renee. She identifies the killer as minor villain Flamingo but also learns about Renee’s history with Poison Ivy. Ivy’s powers and habits can be transmitted by infection, and Alice suspects this has happened to Mary. Mary suggests Alice’s hallucinations are manifestations of her guilty conscience. Meanwhile, Ryan has been invited to dinner by Jada and brings Sophie as a guest so she might bug Jada’s office. The chef serves wine dosed with a paralytic and reveals himself as Professor Pyg, whose life was ruined when Jada fired him. Ryan, Sophie, and the Jets flee into Jada’s panic room after Ryan stabs Pyg. As Ryan leaves to find an epipen for Marquis, Jada denies to Sophie that she knew about the Black Gloves’ human experiments. Jada surrenders to Pyg to protect Ryan, allowing her to use an epipen on Marquis, who recovers and stabs Pyg to death. Jada tells Ryan that she plans to freeze Marquis because he has been a sociopath since Joker shocked him with his joy-buzzer.
