A/N: And finally my OCs get their first proper introduction. This is a sadly short chapter but in the end there wasn't much to write about when it comes to Dahlia at this point of time.

Chapter 2.

Lightning

1986

Dahlia Elizabeth Williams was born to Hannah and Adam Williams on a sunny June day. She was dearly loved even if her parents were busy with their jobs and research. Hannah Williams nee Chesterton was a teacher at Eton while Adam Williams was a doctor at London's biggest hospital.

Thus it was her grandfather Gabriel Chesterton who mostly looked after her during her first years of life.

1991

Dahlia was five years old when Samuel was born. He was a whoops-baby but loved none the less. He was also looked after by Grampa Gabriel. The old man used to be a mechanic and inventor back in the day and the years had not dulled his intellect at all. Intellect which the man could see glinting in the eyes of his grandchildren.

Dahlia was also five when she took apart a VHS recorder and began sorting the pieces into piles. She received her first toolkit from her grandfather then.

1994

Dahlia liked taking things apart and build them up again. Samuel liked to watch and 'help'. Grampa Gabriel liked to teach them about different parts and meanings of machines. He made gadgets and moving knick-knacks and the children loved them.

"I want to be just like grampa!" Dahlia announced. Samuel nodded next to her.

"I'm Spanner." He said lifting a toy spanner in the air.

"I'll be Wrench then!" The two words might be practically the same in meaning but they were siblings so they fit right?

1996

There was an explosion in their 'laboratory'. There was an explosion but no one got hurt. Crackling lightning was shielding them with Gabriel standing tall in front of the children and Wrench crouched over Spanner, green sparks crackling along her skin.

Flames of Dying Will, Gabriel called them and told Wrench to be careful. Mafia had the flames and fished for powerful users. The girl nodded.

"They were so cool…" Spanner stated with the awe of a five-year-old.

"But no telling mum or dad either." Wrench told the boy who nodded.

"Of course not. They are like our secret names." Even after two years, Hannah and Adam still didn't call them by their chosen names. They loved the kids but they didn't understand. Wrench smiled sadly. Both her and Spanner were intelligent and were capable of using that intellect, but their parents just didn't understand to what they wanted to use it. Didn't understand they already had things they loved to do.

1998

Wrench cut her hair and dyed it lime green. She wore boys' school uniform and didn't give a shit of what other girls called her. She had her grandpa and Spanner. They understood her and it was enough.

She also began studying her own flames and their uses under Gabriel's supervision. She wanted to understand them in turn.

1999

Spanner made an internet friend from Japan. Shoichi was the kid's name. Dahlia liked him.

Gabriel Chesterton went to Italy for a holiday. He didn't come back.

Wrench knew how to hack. She began looking for information about the mafia.

2001

Sometimes she was Dahlia, the other times she was Wrench. When she met the prettiest and coolest girl ever, she was Dahlia. She was sixteen and in love.

"Oh, I'm sorry! Let me help you with those." The pretty girl said and helped Dahlia with the books she'd just purchased from Waterstones. Science Fiction for her and some Japanese manga for Spanner. And her two bags used to hold them had fallen on the cobblestones between them.

"Thank you…" Dahlia stared at the girl's sad blue eyes and almost golden blonde hair falling down her shoulders. She was dressed in denim jacket and jeans with a turquoise t-shirt beneath and she was so damn pretty.

"It's alright. I should've watched where I was going." The pretty girl smiled as they gathered the books and placed them neatly back to Dahlia's bags. She couldn't place the accent she had when speaking English but it was pretty too.

"I… I'm Dahlia Williams. Would you like to get coffee with me?" The green-haired girl blurted out before she could stop herself.

The pretty girl hesitated, several emotions flashing on her face.

"S-Sure… My name is Leila Kannas." She blushed and tucked a stray strand behind her ear. She looked so young like that.

That's right… How old was she?

Dahlia met Leila many times and took showing sights of London for her. It was nice and fun and… She loved the foreign girl. It was strange but Dahlia felt at peace with her.

Then she met the girl as Wrench and everything crashed down.

Wrench had been crouched over one of her inventions and fine-tuning it when the door opened. She thought it was Spanner who was one of the few people with a key so she wasn't worried.

Then a familiar voice with wrong tone spoke up.

"You were hard person to track down, Wrench. You cover your tracks well when it comes your transactions and purchases."

Wrench looked up and turned around slowly. Her goggles were obscuring her eyes as she took in the intruder and the lock on the door that was picked open. She tried to swallow around the lump in her throat.

It was Leila. Her hair was pinned up on a hightail and she was wearing a suit with light blue shirt and dull grey tie.

"And you are?" Wrench asked hoarsely and reached up to lift her goggles away.

"Agent Thyme. Of CEDEF…" And the 'pretty girl' trailed off when she saw Dahlia's face. "You…"

"Me. Surprised? I certainly am. What does Vongola's External Information Organization or whatever want with little ol' me?" Wrench asked, leaning against her workbench and surreptitiously glancing around the room to see that all dangerous chemicals were behind locked doors and any tools using fire or gas were put away too. She had just been using a simple drill and screwdriver but one could never be too sure.

CEDEF was mafia. It might've been an intelligence organization but its main focus and allegiances were in the mafia. Whatever they wanted from Wrench, she would decline and if a fight erupted afterwards, she was ready.

"The few gadgets and inventions that have gone into circulation and whose patents have been traced onto you have caught CEDEF's attention." Leila – no, Thyme – started an obviously rehearsed spiel and might've impressed someone else but for Wrench, for Dahlia, it just sounded fake in the girl's mouth. "Thus we've decided to offer you a job and-…"

"No." The young inventor cut in.

"B-But… you didn't even listen to the benefits or…"

"It's still no. I'm not interested."

"I see…" There was underlying danger in Thyme's voice. Like there was no such thing as saying 'no' to the job offer given by the mafia. "I'm afraid I can't let you go then." Remorse. So the girl wasn't mere puppet for her organization.

"Oh, how so?"

"You know about the mafia. You know about me. You know about CEDEF and its connection to Vongola. All the while being a civilian." Thyme stepped closer. "My orders are to either recruit you or to dispose you."

"Yeah, not happening." Wrench snorted and green sparks flared to light across her skin and started travelling along the metal parts of her lab. Thyme's eyes widened before glowing sapphire blue as she drew a gun from a holster at her belt. Wrench lifted a heavy-duty rubber mallet from a nearby desk and let her flames dance across it, hardening the rubber into something as solid as all the metals around her.

"Lightning user…" Thyme glared and pointed the gun at Wrench who was still yet to move aside for cover.

"Rain user." The green-haired girl retorted disinterestedly. "How old are you even? Younger than I, that much I deduced during our dates but now that I know you are an agent… I didn't know CEDEF recruited kids."

Thyme flinched but gritted her teeth.

"I'm fifteen. I've worked for CEDEF for two years. I'm no child!"

"Still basically a kid."

Thyme seemed ready to rush forward and pummel her to the ground instead of making her look like a block of Emmentaler cheese. But in the end, it wasn't needed as a heavy monkey wrench at the hands of ten-year-old Spanner connected with the back of the agent's head.

Wrench let out a sigh of relief. Her lab wasn't destroyed after all. Maybe now she could have civil conversation with her cute girlfriend.

And it was such a relief that she was only a year younger than her too.

Agent Thyme woke up to find herself tied to a chair, with her wrists on armrests thus negating any possibility of secretly breaking out. Wrench and a boy the looked alike to her were bent over something or other and the mallet was within the inventor girl's reach.

"Ah, you're awake. Shall we now discuss things civilly?" Wrench smiled. "Then we can go on a date like we used to."

"D-Date?" Thyme stuttered. "W-What do you mean?"

"A date where we go somewhere cool in London, I tell you random info about it, we take photos, and later we go somewhere to eat."

"B-But… I…"

"You are still Leila Kannas, aren't you? It's your real name, right?" And it was Dahlia smiling and tears falling from Leila's eyes.

"They… They tried to take it away…" The blonde girl sobbed.

The whole sad backstory came out then and Dahlia swore to always support Leila no matter where each of them were.

And they managed to spin things in a way that Agent Thyme and her handler would be the only ones in contact with Wrench and she would be only contracted to CEDEF but not an actual member for them.

(If she wanted some extra information, she could always just hack for it.)

A/N: And done. In the next chapter you'll have Leila's story. In the meantime, thank you everyone who have followed and favourited this story. I hope you enjoy this and also spare some time to leave a comment too.
