Batman and Ivy work together to find a killer carrying out a series of Ivy-like murders at Arkham. His butler, Alfred Pennyworth, notes that Batman has been poisoned by the flowers. Batman tells Alfred he must kiss Poison Ivy for the cure, and that if he fails Alfred must kill him. Ivy and Batman confront each other, where Batman warns Ivy that he'll have to knock her out to kiss her to make sure that she doesn't kill him when he passes out after being cured. Ivy insists for him to trust her, despite Batman's doubts. Batman at first decides to punch her, hesitates, then they embrace and kiss passionately instead. Upon being cured, he falls, but saves himself, and saves Ivy as Gotham Tower collapses when — assuming Batman dead — Poison Ivy tries to kill herself, once more insinuating that it is more than just lust she feels for him. Ivy and Batman share a moment together speaking, watching her plant creations create light, and Batman compliments her on her talent. Batman takes Ivy back to Arkham Asylum, so that Ivy can finish her rehabilitation. Discouraged, Ivy complains to Batman about the lack of light in her cell, and Batman responds that there is nothing he can do about it, before departing. Transferred to a new cell the next morning, Ivy is stunned when she discovers that someone has had her room moved to a special cell where she can be in the sunlight, and has been filled with flowers as a gift. Upon being told some "anonymous benefactor" wanted to make sure her time isn't as daunting as it might have been, a touched Ivy smiles and thanks Batman. In Detective Comics (vol. 2) #14 (January 2013), Ivy kisses Batman, trying to gain control over him via her toxins, and saying, “You're the only one for me Batman, you know that right? Nobody else even comes close. Not anybody.⁣⁣⁣” Rather than using an antidote, he rigs his visor to show him certain set of visual stimuli that will effectively erase his short-term memory, thereby erasing any commands she gives him as well. Aware of his resistance, she tries to appeal to his sense of morality. In Gothtopia, Batman comes to her rescue when he realizes she was telling him the truth, even though he put her in Arkham. First she punches him for not believing her claims,
