Arleen managed to reassure Dr. Leland and Harley that she was fine after her ordeal, fine enough for them to go to lunch and leave her to have a short rest to recover. "Ok, if you're sure, sweetie," said Harley. "J.J., you coming?"

"I think I'll stay to look after my sister, Harley," replied J.J.

"Oh. Ok," said Harley, clearly disappointed but not about to argue in the circumstances. "I'm sure someone can direct you to the cafeteria if you change your mind."

"Yeah, I'm sure they can," agreed J.J., smiling. He shut the door after her and his smile fell. "But I won't," he muttered, heading back over to Arleen, who sat on the couch. He sat down next to her. "You ok?" he asked gently.

"I was just attacked by my father, J.J.," muttered Arleen. "Of course I'm not ok."

"Leenie, that wasn't Dad," said J.J. "I mean, that was Dad, but he didn't know you were you, who you really were, I mean…you know he'd never hurt you."

"I know," agreed Arleen. "But it's still a pretty disturbing experience."

"Hey, try having your Mom be in love with you!" chuckled J.J. "This whole going back in time thing is a really disturbing experience all round. When we get back home, I'm not gonna recommend it to anyone!"

"Are we gonna get back home, J.J.?" whispered Arleen, tears in her eyes.

"I promised we would, didn't I?" asked J.J. "Don't worry, little sis. Your big brother is gonna make this right."

He kissed her cheek and she hugged him tightly. Then she stood up. "C'mon," she said, grabbing the emergency axe, and then smashing the glass to activate the fire alarm. "Let's get to work on that breakout."

The alarm blared through the asylum as staff headed outside. Arleen and J.J. peered cautiously out of the office and then snuck toward the cell block, losing themselves in the crowd. When they reached the cell block, two guards were on the radio, trying to confirm if the alarm was a drill or genuine, in which case they'd need to evacuate the lunatics from their cells.

J.J. picked up a fire extinguisher by the door and then nodded at Arleen, who slammed the blunt end of the axe into the guard's skull, while J.J. knocked out the other one. Then they strode into the cell block.

"Hi, Mr. Tetch," said Arleen, stopping in front of Tetch's cell and smiling. "You're to come with us, please."

"Oh," said Tetch, clearly surprised that he was the reason for the false alarm. "I see. Who are you?"

"It's a long story," said Arleen, raising the axe. "We'll explain it to you once we're outta here."

She smashed the glass with the axe, and a few blows created a hole big enough for Tetch to crawl through. "C'mon, J.J., let's go," she said. "J.J.? J.J.!" she snapped, to see her brother in front of Poison Ivy's cell.

"C'mon, Leenie, as long as we're busting people outta here, why don't we help Ivy out as well?" asked J.J., smiling pleadingly.

"J.J., we don't have time!" snapped Arleen. "Let's just go before more guards get here!"

J.J. sighed heavily. "Please don't hold this against me – I tried," he said to Ivy.

"You're too cute to hold anything against, handsome," purred Ivy. "Except me, if you get what I'm saying. If you bust me out, of course."

"Leenie, c'mon…" began J.J.

"We're going!" shouted Arleen, grabbing her brother around the collar and dragging him off.

"Try not to remember this in the future!" called back J.J.

They headed back to Harley's office with Tetch in tow and climbed out the window.

"Mr. Tetch, tell me you know how to hotwire a car," said Arleen as they reached the parking lot.

"I'm afraid not," said Tetch. "I assumed since you two were organizing this breakout that you'd have arranged some form of transport."

"Believe me, we're just improvising," replied J.J. "Having to work with what we got, and right now that's not much more than our brains. I guess I can try my hand at hotwiring…"

"No need, kid," said a voice, suddenly. "I got this."

They heard an engine starting, and turned to see the Joker standing by a vehicle, slamming down the hood and smiling. "How did you get out of your cell?" demanded Arleen.

"The same way I got out earlier," retorted Joker. "Anyway, it's rude to break a guy out and not invite everyone else. Very inconsiderate – didn't your parents teach you any manners?"

"Yes, they damn well did!" retorted J.J. "But if they're going to teach us manners in the future, let alone exist, you've got to stay here with Dr. Quinzel!"

"You two do a lotta crazy talking, y'know!" chuckled Joker. "Sure you don't belong in the asylum yourselves? Maybe I oughta just leave you here along with the nutjobs and the hat nerd!"

He opened the car door. "But something about you two seems kinda…familiar, I guess, is the word. Although I'm pretty sure we've never met."

Arleen and J.J. shared a look. "We can't explain it to him now – we don't have the time!" said Arleen. "Let's just take him with us and we'll get him and Mom together later! It's not like he's going to win her on his own – you've seen where the old Joker charm got him earlier!"

"I still have faith in the old Joker charm!" snapped J.J. "But fine, let's go!"

He, Arleen, Tetch, and Joker all climbed into the car. "Hang on to your hats and Hatters, kiddies!" he chuckled, as he slammed on the gas pedal and burst out through the gates of Arkham.

"Boy, we are gonna blow his mind when he finds out whose kiddies we are," whispered J.J. to his sister.

"Blowing the Joker's mind?" replied Arleen. "That would be a first."
