Lily stalked into the FBI building, her long, dark red hair loose with its bluntly cut fringe making her an easy person to spot. She smiled politely at other agents as she took the elevator up to the BAU bullpen area that she shared with her friends, Agents Prentiss, Morgan and Dr Reid. Agents Jareau, Rossi and Hotchner had their own offices above the bullpen while their Technical Analyst, Penelope Garcia, had her own office down a long corridor. It was this office that Lily made her first stop of the day. She knocked on the office door.

"Enter and be recognized, mortal!" the cheery voice of their perky, blonde computer whiz made Lily smile and open the door.

"I beg an audience with the Oracle of Cyberspace, Oh Supreme One," Lily mock-bowed, grinning the whole time.

"Granted, Moonflower," Garcia smirked at Lily. Ever since Garcia had found out that Lily's full name was Lily Luna Potter, she had taken to calling her "Moonflower". It was incredibly 60's, but Lily didn't mind.

"I need a favor, Pen,"

"Anything," Garcia could see how serious Lily had grown.

"There's a British terrorist in DC that my father was kind enough to give me the heads up on. This is what he looks like," Lily passed Garcia a muggle photograph of Fenrir Greyback. Garcia winced.

"Wow. That guy looks a lot like Sabertooth," Lily nodded at the reference to the X-Men villain.

"And just as dangerous, super-powers or not. Since Dad's been looking for him for years, he thinks that Greyback, that's his name, will try to get to me here at Quantico. I need you to keep an eye on all entrances to the building,"

"Got it. But shouldn't I inform the authorities about him?" Garcia looked curious and confused.

"Leave that to me," Lily said calmly. She knew that if Greyback wanted to get into the building, no muggle would stop him, guns or no guns.

"Alright, sugar, if you say so,"

"Thanks, Pen. Give me a ring if he does show up, will you?" Lily gave her a reassuring smile. Garcia nodded, a bit confused, but still willing to help. Lily nodded gratefully before walking out of the office and to the bullpen, where her colleagues were sorting out their desks.

"Morning, Red," Morgan greeted with a pearly smile.

"Hey," Emily waved with a tired smile.

"G'morning, Lily," Reid walked after Lily, handing her a black coffee mug with her name and the crest of a roaring lion printed on it in red and gold, her usual mocha cappuccino steaming inside as Reid held his own white mug of 1 part coffee, 3 parts sugar, in his other hand. He gave her a lopsided smile as she took her mug happily.

"Morning, guys. Cheers, Spence," she grinned and took her seat in the cubicle next to Reid's. JJ had apparently been the only person in the whole world to call Reid "Spence" before Lily joined the team. Now that she and Reid were best friends, he hadn't objected when she had adopted the nickname for him too, having called her "Lil" at times as well. She would admit, only to herself, that she felt a little thrill every time he called her Lil. None of her relatives or friends called her that, preferring "Lily", "Lillers", "Potter", "Lily-love" or "Lilyflower".

"Anything new happening?" she asked, sipping her coffee with a small sigh of relief.

"Nope, another boring day of paperwork," Morgan groaned, looking at his stack of papers in despair.

"You make it sound like you want a serial killer to pop up," Lily arched a wry brow at him.

"Don't jinx it, Lily," Emily sighed, beginning on her own stack. Lily chuckled and grabbed a pen, pulling the first file over to her. She preferred quills, and wished she had a Dicta-Quill so she could just order it what to write and it would obey, saving her hours of filling them out the Muggle way. It was one of the things she missed about the wizarding world, but she would not let James hear that.

She glanced up at the photographs on her desk and smiled fondly. One of them was a silver-framed, Muggle photograph of her immediate family – her father, mother, brothers and godbrother, Teddy Lupin, when Lily had just graduated from Royal Holloway. Harry and the boys were all dressed in different colored muggle suits, and only Harry was wearing a tie. Ginny had put her hair into a bun and had worn a simple black, knee-length dress, since that day was Lily's. Lily did not have her bluntly cut fringe at the time, but her hair was in a long feather-cut. Her eyes were outlined in kohl, with dark red lipstick. She had on a green mini-dress under her black graduation robes and she held the scroll in her hands triumphantly and happily. James and Al flanked her, their arms around her tenderly as they grinned at the camera, Al looking like the spitting image of their father, without the glasses or scar. Teddy, his hair shaggy and brown, with the sparkling grey Black eyes, stood behind the Potter siblings, his arms encompassing all three of them and his height making it easy for him to do so. Ginny and Harry stood at either side of their kids (Teddy was a surrogate Potter anyways), beaming with pride.

The next photograph was of her with her brothers, Teddy, Scorpius Malfoy and her various cousins – Victoire, Dominique, Louis, Fred, Roxanne, Molly, Lucy, Rose and Hugo. Lily, Molly and Hugo had their arms slung over each other's shoulders, as did Al, Rose and Scorpius, Fred, Dominique, Roxanne and James, Louis and Lucy and finally, Teddy and Victoire (although Teddy was standing behind Victoire, his arms wrapped around her waist). Teddy had made his own hair red for the occasion, so the only non-red-heads were, in fact, Roxanne, Fred, Al, Victoire and Scorpius, the latter two of whom were the only blondes. Each group was doing something different. Teddy and Victoire were looking at each other lovingly while Fred, Roxy, Dom and James were making faces and rabbit ears, grinning mischievously. Louis and Lucy stood back-to-back, their arms folded as they smiled at the camera while Al, Rose and Scorpius were laughing uproariously. Lily, Molly and Hugo were grinning as they did the "See-No-Evil, Hear-No-Evil and Speak-No-Evil" gestures. Lily smirked at the irony of her being "See-No-Evil" when, in fact, she saw evil everyday, paperwork included.

The third photograph was split in half. The first half was a photograph of her maternal grandparents and of her aunts and uncles standing outside. The second half was of her paternal grandparents' wedding, where her grandparents beamed at the camera and were flanked by their best man, Sirius Black, and Remus Lupin (Teddy's father). Peter Pettigrew had originally been in the photo, but Lily had been able to cut him out. Though he had helped her father escape from the Death Eaters when he was 17, he was a traitor through and through to Lily.

The fourth photograph was of a sallow-faced, hook-nosed man with greasy black hair and a stern demeanor. This photograph was secretly a wizarding one, but could only be activated by secret words that only Lily knew. The photographic figure could hear and see everything that went on, but could not communicate with anyone without the password. The frame for this one was a simple one of black.

The final photograph was more recent, and taken here in America. It was of Lily out for drinks with her team. Hotch sat in the corner with his son, Jack, the former of whom was smiling slightly, but whose eyes were sad. The death of his wife still weighed heavily on his conscience. Jack was beaming happily, with a smiling Emily on his other side. Next to Emily was Garcia, colorful as always, with Kevin sitting next to her, smiling a bit awkward. Morgan was next, grinning as only he could, with JJ and Will holding Henry right next to him, smiling lovingly down at their son. Rossi smiled next to Will, with Lily laughing on his other side, her arm thrown around Reid's shoulders. Reid looked a little flustered, but still smiled at the camera. The photograph had been taken by a passing waiter and Lily had written "MY ALL-AMERICAN FAMILY" on the back, hidden by a simple wooden frame in green.

Shaking herself out of memories, she bent her head and returned to her paperwork.

At noon, Lily received the phone-call she had been expecting.

"Moonflower, that guy you warned me about? Yeah, he just showed up and walked into the building not three seconds ago," Garcia told her hurriedly. Lily swore.

"Garcia, record this message for me and show it to the team as soon as you can,"

"Okay, one sec…alright, ready, set, go,"

"Guys, I need you to follow one instruction, and one instruction only. Make sure my father listens to this recording. His number's in the file. Dad, by the time the FBI gets this, I'm sure the wolf will already have me. Al's namesake can be found in the pen and solemnly swears he is up to no good. My own location will have to be profiled from examining the wolf's life and background. Tell the team everything muggle, but only the youngest should be omniscient. I won't receive a bite, because he wants to piss you off. He'll only torture me until you find me through his taunts and only give me the bite when you're there to see it. The key's under the flowerpot. To everyone else, I'm sorry, but I should be the one to tell you everything that you won't know. All my love to you. End message," Lily heard Garcia tapping her keys, and knew the message was saved. "OK, Garcia, get everyone out of the building right now. If this guy's in the building, he'll kill anyone who gets in the way of what he wants,"

"Which is?" Garcia asked breathlessly as the alarms began to ring and everyone dropped their things, heading for the stairs.

"Me," was all Lily said before she hung up and threw her purse into her bottom drawer and locked it, leaving only her wand and gun on the table.

"Lily, come on!" Reid beckoned hurriedly. Lily bit her lip and waved Reid on. He looked torn, but a simple look from Lily made him nod stiffly and follow everyone else out. She crawled under her desk and waited for everyone to leave. Then, she crawled back out and looked around. The bullpen looked eerie, with everyone gone. It was like a ghost town. Lily walked into the centre of the bullpen and checked her gun. The special bullets she'd loaded that morning were there, and she held her wand in her right hand. She had been right-handed growing up, but she had broken her right wrist at university and had been forced to learn how to use her left hand. Thus, she had become ambidextrous and learned how to shoot left-handedly. This now came in handy while she could use her wand and her gun at the same time. The feeling of a menacing presence entering the bullpen made her look up and her lips quirked into a humorless smirk as she took her stance. He might take her, but she would be damned if she didn't go down fighting the whole way.
