Red Hood visits John Constantine for help with an undercover mission.

The Gotham night sky hung serenely over the city of sins. While other cities were known for their teaming nightlife, Gotham City had a very different kind of nightlife. Automatic pops echoed, police sirens blaring in the distance. The Bat Signal hanging overhead. On the outskirts of town, far away from the chaos of the concrete jungle, there lied a qauint little bar. Void of all life save for two men, one clad in black and red with a crimson helmet to boot and the other a blonde in a trench coat.

"So let me get this straight," John took a drag from his cigarette, eyeing the vigilante with furrowed brows.

"You came all the way out to me favorite pub to bother me with yer nonsense," he rolled his eyes, taking a swig from his bottle. He glanced over at Red Hood.

"Yes," Red Hood folded his arms, nodding.

"Somethin' about ye need'ta get in to some bad guy kangaroo court meetin' and ya need Harley Quinn of all people to testify against the crazy clown man so the other baddies lop his head off," he paused, pointing to Jason's bulky physique. There was no way in bloody hell he was going to blend in with the big wigs, even if he did steal their clothes. Too buff and towering to be Riddler, Scarecrow, Mad Hatter, or Joker, but not quite shredded enough to be Bane. And that's assuming he was a good enough actor to pull off the part. Maybe he could get by as some lowly goon, but wandering into the hornets nest with a less than ideal disguise would spell **** for the former boy wonder for the second time.

"Yep."

_"So you nabbed blondy there and took her here cuz she didn't wanna attend said meetin'..." _he paused and gestured to the **** Harley Quinn on the rustic floorboards.

"That's right."

"Under the assumption that I was gonna be charitable enough to do some... as ye put it... 'weird magic stuff' to make her go and give you some kinda fancy shmancy magical disguise so good it could pass a damn DNA test."

"Yeah, no you nailed it so far."

"What the hell is wrong with ye? Yer little resurrection scramble yer noodle, mate?"

"You don't get it," Jason sighed.

"Really? What's there not to get? Aside from the fact you kidnapped a lass?"

"I need her to testify against Joker! It's the only way he'll face justice for his crimes," Jason admitted.

A mock court ran by the worst criminals Gotham had to offer didn't exactly fit Bruce's definition of justice. It spat in the face of everything Batman believed in. Everything he tried to instill in Jason, before and after his demise and resurrection. But it was what he needed for closure. To know that clown could never hurt anyone ever again would be a good first step to healing. Truly healing. Even if it meant Joker would get murdered by his fellow villains. He couldn't picture an end sweeter for the psychotic Clown Prince than that.

"So bloody ask her to if it means so much to ye! Well, not now. I doubt she'll be very cooperative since ye whacked her on the noggin'."

"I tried that. She wouldn't listen. She doesn't have it in her to face him again! But I do! So... Just do some of your hocus pocus mumbo jumbo and let me control her mind or something for an hour or two."

"Do you get all your grand schemes from the back of a cereal box or a comic strip? Mind control? What do I look like to you? Starro the bloody Conqueror?" He huffed.

"Why does everyone and their mum think magic is so bloody easy? Everything has a cost, lad. What yer asking for is something that requires real potent magic. Ancient type stuff. Not the kinda thing you'll find in yer grandmum's attic."

"I came to you because you're the best around, Constantine. Everyone knows that."

"Bloody damn right I am..."

"So can you do it?"

John let out a deep guttural sigh, slumping over the counter and finishing his bottle of

"Bollocks... What's in it for me..."

"Hm... I'll never bother you again?"

"Temptin', what else?"

"I'll... get you a case of your favorite beer?"

"Make it a dozen."

"Deal."

John casted his bottle aside in a random direction, the glass shattering as he cracked his knuckles and stretched. Now on his feet, he made a gesture with his hand, speckles of golden light glistening from his fingertips. He plunged his hand deep into the confines of his trench coat.

"Boon of Anubis, no, Untethered Shadow, no, Wise Helm of Omnipotence, no..."

He turned to the side, allowing his whole arm to slid into the pocket dimension that was his coat pocket.

"There we are! Necklace of Transference."

He pulled out a golden necklace.

"What kind of name is that?"

Jason snickered.

"I don't name the mystical junk, mate. You want it or not?"

"Sure, if it works. This thing will let me make her go?"

"Put it on and find out."

Jason hesitated for a moment, eyeing the golden necklace warily. Taking a deep breath, he grabbed it and put it on. The moment it touched his skin, he could feel the power coursing through it. In the blink of an eye, he suddenly felt his body becoming ethereal, like a spirit.

"W-what the hell is this?! I'm a ghost?"

As he looked down at himself, his form became a transparent, red hue. John must've given him the wrong magical doohickey!

"Dammit, John! Hey! John!"

He called out to the sorcerer but he didn't seem to hear him.

"Huh...?"

Jason stumbled abruptly, a tugging sensation taking over his body. He looked the direction he was being pulled, spotting Harley Quinn, lying **** on the floor.

"Wait a second... Hey! Wait!"

Jason struggled fruitlessly, the ethereal **** yanking him across the room and sucking him inside Harley's **** body. An array of images shot through Jason's mind, Harley's life flashing before his eyes. Growing up in Gotham, going to college at GSU, graduating with a PHD, working at Arkham Asylum, meeting the Joker. His mind raced, unable to keep up as his mind settled in to its new physical form.

"Mmm..."

Jason stirred, feeling returning as he moved to sit up. His hand wandered to the back of his head, his now bare fingers grazing the back of his skull where he had struck her to knock her out.

"Damn... what a weird drea-" Jason's face turned red, his eyes shooting open upon hearing Harley's high pitched soprano leave her lips.

"My voice!"

Sitting up fully, his gaze drifted down to the fleshy mounds on his chest encased in a black and red tank top. The article gave Jason a good look at his (her?) deep, supple cleavage. His pale, toned stomach was exposed, his borrowed voluptuous ass and thighs packed tightly into her black and red leggings. The weight of her long pigtails grazed his exposed neck and upper back.

"John, what the FUCK?!"

"I'm guessing by your 'deer in headlights look' that it worked! Take a look, mate."

Constantine tossed a handheld mirror to Jason, who clumsily let it hit the floor. He picked it up off the ground, Harley's shocked face looking back at him.

"Right. Gonna take a sec for yer body to settle in."

"Why the hell am I Harley?! This isn't what I asked you to do!"

"Looks like it, lad, or should I say lass? Lord knows what is and isn't politically correct these days... Anyway, yeah, it is what ye asked for. Ye wanted a disguise and to control Harley, so now ye got both. A 'thank you for humoring my arsenine request' would be nice."

"So you thought sticking me in the body of my killer's girlfriend was a good idea?"

Jason didn't want to be a girl to begin with, let alone be in the body of Harley Quinn of all people.

"Two birds with one stone as far as I'm concerned..."

'It's actually ex-girlfriend.'

"Who said that?"

"I said 'two birds with-'"

John raised a brow, Jason interrupting him.

"No, not that!"

'Me? I'm you, silly. And we aren't gonna testify! Lame! We're gonna have a night out on the town!'

The voice sounded like... Harley's...? But it was in Jason's borrowed head...

"Something wrong, mate? Aside from yer moanin' at me for helpin' ye?"

"I -I can hear her. I can hear... Harley...?"

Constantine scratched his chin for a moment.

"Huh, well that's not right. I guess a side effect is the other person is still in there rather than a whole hostile takeover?"

"Dammit, John. Why did ya do this to me?!"

'I am so confused right now.'

"Shut up!"

Jason pointed at John, snapping at Harley, finding it odd how naturally Harley's tone and dialect left her mouth.

"Looks like this isn't a body hijacking after all, mate. Ye ain't stealing the thing entirely, and since your form was corporealized, it seems ye both are sharin' the same brain space," He lit another cigarette and took a drag.

"In other words, yer just pushing Harley out of the drivers' seat fer a while. It'll be up to you to keep her from makin' ye do things ye don't want."

Jason clenched his fists. He wanted to deck the magician but knew it would get him nowhere.

"Just change me back..."

He shifted his weight to one leg awkwardly, folding his arms under his bust, unknowingly taking on a rather feminine stance.

"Not gonna happen, ye got at least a few hours before I can do that. Not good fer yer mental stability to be boostin' your mind in and out after only a couple minutes. 'Less ye wanna really end up as batshit as her."

Jason sighed, realizing he really didn't have a choice now. The only way Harley was going to testify would be if he used her body to do so.

"Fine... I guess I'll... Go testify...?"

"I'll be here."

Jason went to walk but tripped on one of Harley's heels, cursing to himself. John shook his head, chuckling to himself as he popped open another beer.
