Okay, so I said I wasn't going to do a sequel, but I was stuck for ideas for July's Camp Nanowrimo, and this kind of crept up and bit me on the ass.

The prequel to this is The Secret Life of Epsilon Brown, and you can find the link on my profile page. But if you don't want to read it… basically Harry Potter was brought up as Epsilon Brown by Men in Black. It is SERIOUSLY AU.

The Peculiar Prodigy of Epsilon Brown

It's been 14 years since the war, and Epsilon is back working for MIB. But when a one night stand turns into a ten year old child, can he cope with being thrust into parenthood? With his son about to embark on his own time at Hogwarts, Epsilon's own past is about to come barrelling back. Can he reconcile with those he left behind, all those years ago?

Prologue - August 12th 1998 (19 Years Old)

Epsilon was quite certain that he was drunk.

He was also vaguely aware that he was most likely in a Wizarding establishment. In London.

This was probably a Very Bad Idea.

He downed another fire whiskey anyway, this wasn't the time to develop a sense of responsibility. He had too much of that in everyday life. He was done with responsibility. He brandished his glass to emphasise his silent declaration, and laughed slightly as his vision blurred.

He was so drunk. His father was going to kill him in the morning.

"Nice suit, stranger."

He turned to see a girl, more or less his age, leaning against the bar alongside him.

"Hey there," he said with a lopsided smile. "How you doin'?"

She smiled back at him, before turning to the bartender.

"One fire whiskey, please."

"Make that a double," said Epsilon. "Her drink on me."

"You don't have to-"

"It's my pleasure," he told her, fumbling in his pockets for the last of his change. "You, my Lady, are clearly not drunk enough."

She laughed lightly and took the drink.

"Whereas you have had a bit too much already."

"Hey, gimme a break," he whined. "I'm not legal yet back in the States. Lemme enjoy my freedom."

"Ooh, you're American," she said, her blue eyes sparkling up at him. "Where are you from?"

"New York. You seem somewhat familiar, have I been drinking with you before?"

"I highly doubt that. Did you go to Hogwarts?"

"That I did. Epsilon Brown, Hufflepuff alumni at your service."

"Julianna Cook, Ravenclaw."

"Charmed. I think I remember you now, you were the year behind me. Another drink?"

"I'd love one."

A few more drinks later and Julianna had joined Epsilon in a contented haze, as she blearily filled him in on her work into experimental Arithmancy. Epsilon had to admit that it was slightly over his head. He had only covered basic arithmancy at school, and mathematics had never been one of his favourite subjects despite MIB giving him a very thorough grounding. Eventually though the girl's enthusiasm petered out, and it was her turn to ask a question.

"So what are you doing in London? They say you vanished after the war."

Curious. Evidently she was one of many who hadn't made the connection between the mysterious Epsilon Brown and the believed-dead Harry Potter. It was quite a relief.

"Workin' a job," he told her, his words starting to slur slightly. "A bunch of Krellites flew in from the Adina system, an' tried to settle in London without proper affi- other- authentication."

"I see."

Epsilon suddenly noticed that a lock of Julianna's brown hair had fallen in her face, and was now covering one of her eyes. This was unacceptable.

Her breath caught as he brushed it back behind her ear, and she pulled him down by his shoulders to kiss him.

This is a really bad idea, his instincts were screaming. Really irresponsible…

But he was too drunk to listen to his instincts. He had no inclination to be responsible tonight.

Besides, Julianna was really pretty.

The first thing Epsilon was truly aware of was the high pitched beeping that was burrowing into his brain and causing indescribable amounts of pain. He groaned and rolled over, almost immediately colliding with something warm.

"What…"

His eyes widened as he saw Julianna lying next to him, still fast asleep, and he looked around wildly as vague memories from the night before filtered into his consciousness. He was in Julianna's apartment, in the tiny bedroom that obviously doubled as a study. He gaped at the stacks of paper that littered the desks, and the equations that papered the walls. This girl was a genius.

The beeping started up again. With another groan he plucked his trousers off the floor, fumbling in the pockets for his communicator.

"Yeah?" he asked quietly, his voice hoarse. "What is it?"

"Epsilon Brown, where the hell are you?" came his father's voice. "We were scheduled to leave ten minutes ago. Did you even come back to the hotel last night?"

Epsilon swore as he checked his clock to find that his father was right.

"Sorry, dad. I'm… actually, I'm not entirelysure where I am."

There was a moment's silence.

"Kid, what the hell have you done?"

"I'll get back to you when I figure that out," he told him. "Look, I'll be there… soon. I'm sorry about this."

"Just get your ass back here now!"

Epsilon sighed as the connection was broken.

"Are you in trouble?"

Julianna was opening her eyes.

"I'm sorry," said Epsilon. "I didn't mean to wake you."

"S'okay," she murmured. "I guess you need to go now."

"Uh, yeah. Look, about last night, I'm sorry, I don't normally… do that."

"Me neither," she said sleepily. "Don't worry about it, Epsilon. My friends took me out last night to 'loosen up'. I guess they were right."

"Where am I? I need to get back to the rendezvous point at St Pancreas Station…"

"This is Chiswick," she told him. "But you can use my floo, if you like."

"Thank you," he said, awkwardly gathering up his clothes. "Good luck with your research."

"It was nice to meet you," she said. "Uh… can you show yourself out?"

"Sure thing," he said. "Goodbye."

"Yeah, see you around, I guess."
