He turned into Harley Quinn fully

“Kid, are you okay?”

Harleen's eyes were wide and full of concern, her demeanor completely different from the reckless villain she had been moments before.

“Yeah, yeah, I’m fine, doc. But looks like you two ain't,” she glanced at the both of them, her voice coming out in the telltale accent. She really did sound like Harley now, from the high pitch to the New Jersey twang.

Pamela - not Ivy anymore, but Pamela Isley, who had by now regained her footing, looked at Damian with a confused expression.

_“What’s going on, Harleen?” _she asked, her voice sounding drained.

“Why are there... two Harleys?”

“I… I think the chemicals did something, undid the stuff Joker did to me and what your plant serum did to you.”

Harleen said, looking at Pamela then back at Damian. She took a deep breath.

“And uh... this ain’t my twin sis, Pam. This is… This is Robin. Y'know, B-Man's brat?”

Pamela's eyes widened at the revelation, she looked back at Damian, assessing her in this new context.

“Robin?” she echoed, looking'Harley' up and down with disbelief. “But… he’s... a boy...?”

“She’s wearing a very advanced Wayne Tech suit,” Harleen explained, trying to keep her tone steady. “Something designed to help in undercover operations. It uses some kind of sophisticated tech to... well, make her look and act like me.”

Damian crossed her arms, a scowl on her Harley-painted face. Despite the suit, her annoyance and frustration were unmistakable, classic Damian.

“I didn't choose this, ya know.” She grumbled, the words not entirely matching the tone of her voice. “I was trying to sneak out, Harley caught me, and then…” She gestured vaguely at her body.

"Yeah, I found ya dressed as Catwoman and decided to give ya a hand," Harleen snickered. "Ya shoulda seen her..." Harleen maintained her sense of humor, though her lunacy had been sapped from her mind.

"You promised not to tell anyone about that!"

Damian snapped.

"It's Pam, kid. Chill out," Harleen gestured.

Pamela and Harleen exchanged a glance, both seeming at a loss of what to do next. The absurdity of the situation was hard to ignore: Two former supervillains, cured of their madness, standing in a wrecked chemical factory with a boy who was now stuck looking and sounding like one of their villain personas.

Harleen sighed, running a hand through her now natural hair.

"Guess we have some work to do. We need to get him back to the Batcave as soon as possible," Harleen decided, a determined look in her eyes.

"This could have side effects we don't know about. Plus, Bats is gonna wanna know what happened here."

"No, ain't way we're tellin' Batman!"

"Listen, kid, the only way we're getting that suit off ya is through the Batcomputer," Harleen explained.

"But... but... we can't take Poison Ivy into the Batcave!"

"You mean Pamela Isley? Red won't hurt a fly without the murdery plant juice coursin' through her, right?"

"Not quite how I'd put it, but yes," Isley nodded.

"Bats is definitely gonna wanna study us up close once we tell him what happened. He's also gonna wanna make sure you're okay. He might be pissed off but you're still his daught-errr-son." She went on. "Tell ya what, I'll make sure he directs all his anger at me and not at you for sneaking out. If he asks, it was all my idea, okay?"

Harleen held Damian gently by her shoulders, giving her a reassuring smile. It was like night and day dealing with Harleen as opposed to the psychotic clown princess he knew her to be. She was calmer, logical, and almost motherly.
