Set after Ingrid's arrival, but before Emma's.
Set before the events of Gotham episode, "What the Little Bird told him"
Gotham
An undisclosed warehouse.
Fish Mooney and Butch Gilzean were meeting with Carmine Falcone.
"So, Don Falcone," Fish purred, stepping up to him with confidence, "why did you call this meeting? What do you have to offer?"
"Oh, you'll see," Falcone said, his lips forming a sly smile. "Victor, if you please."
Victor Zsasz removed a giant sheet from something under wraps. When the sheet was removed, Fish and Butch saw a giant machine in front of them, which looked similar to a giant ring with lights.
"What is that?" Fish asked, aghast.
"That, my dear, will make all our fondest dreams come true." Falcone said, "My men stole this device from Gothcorp labs last night. As far as I can gather, it is an untested experiment that functions as a gateway to other worlds."
"And how could this possibly help us?" Fish asked.
"Well, according to the research my men found in the labs, some of these worlds contain powerful elements, unlike our own. If you can bring back some of these elements, we can use them to control this city, perhaps even the world." Falcone said.
"Me?" Fish scoffed, "You want me to go in there and travel to who knows where? You can't be serious! With all due respect, you belong in Arkham if you think this crazy sci-fi scheme of yours is going to work."
"Oh, it will work, and I'm very serious." Falcone said, "but don't worry, though, you won't be alone, you'll have your man Butch with you, to protect you from whatever comes your way."
"You know I can take care of myself!" Mooney snapped, "Besides, I'm not stupid! I know you want me out of the way so can take over my operation!"
"Believe me, Fish, you have my word that I will not take advantage of this. If can get me something to control this town, you and I will be the leaders, and we'll crush Maroni and his ilk beneath our feet."
"OK, let's say I do go through with this…harebrained scheme. How do I get back and how do I know where I'll end up?"
"The answer is simple," Falcone said, "along with this machine and the research my men stole, there also prototype wristbands with built-in microchips for tracking and to determine where you're going."
"And that is?" Fish asked, still skeptical.
"All I can gather from the readings, is it's programmed to put you somewhere in Maine, in the year 2001." Falcone said.
"All right, I'll do this," Fish said, after a moment's pause. She reached out and grabbed the bands for both her and Butch. "But in return, you have to promise me something."
"And what's that?" Falcone asked.
"That you'll stay far away from my club or any of my associates." Fish said.
"You've got yourself a deal, Fish." Falcone said, as he shook her hand and kissed her on the cheek. "Victor, power it up."
Zsasz turned on the machine. It crackled with electricity and glowed blue.
"Have a pleasant journey." Falcone said, as Fish and Butch stepped through. Moments later, the man known as Oswald Cobblepot came waddling forward out of the shadows. "Keep an eye on them, my friend."
"Will do, Don Falcone," Oswald said, as he put on a wristband, "but while I'm gone, Don Maroni will—"
"I'll take care of Maroni," Falcone said, "you just make sure Fish gets what I need."
"Yes Sir," Oswald said, "I won't let you down, Don Falcone."
He stepped through the portal. On the other side, Fish and Butch got out on an open road, surrounded by forest.
"Well, where are we?" Fish asked.
"According to Falcone, we're somewhere in Maine." Butch replied.
"I know that, Butch," Fish said, "but why would Falcone send us here?"
"I don't know, boss," Butch said, "but I think I know someone who might."
He grabbed Oswald.
"H-Hello, Ms. Mooney." Penguin stammered.
"Well, if it isn't my little Penguin," Fish said, "you'd better start chirping, or else I may get hungry and decide to cook up some roast penguin!"
