So, I recently got into the show Phineas and Ferb, namely because it's clever, entertaining and heart warming. But, after watching nearly every episode on the internet and repeated scourings of wikipedia, I couldn't find anything about the missing bio parents (Phineas's bio dad and Ferb's bio mom) so my diabolical mind set a working on this.

As usual, I own nothing (except the characters I make up which should be obvious 'cause they're not on the show) and I hope you enjoyed.

The alarm clock sounded at precisely 7:30 AM on June 14, a week in to summer vacation. While most children their age would still be in bed for the next two hours at least, the boys of the Flynn-Fletcher Family did not believe in wasting time. Phineas, the younger of the two, leapt out of bed first and grinned at his step brother.

"Beat 'cha again, slowpoke!" He laughed. "Come on, let's go get breakfast!"

Ferb smiled and slipped out from under the covers as well. Phineas was already pulling on his orange and white striped t-shirt and blue jean shorts. Ferb buttoned his own shirt and pulled on the same pair of purple pants he always wore. Actually they were a different pair of purple pants than yesterday. Phineas and Ferb had closets full of the same style of t-shirts and slacks. The outfits were comfortable and the boys were of an age that they did not care a thing about the changing world of fashion. Besides, with the activities the boys usually engaged in, having clothes they could get dirty in was a plus.

Ferb could hear Phineas already racing down the stairs, greeting their sister Candace on her way to the bathroom. Candace muttered something angrily and Ferb hurried to join his brother. Candace was sixteen this summer and still, apparently, bitter over her ineffectual attempts to "bust" them for their many projects over the summer. Projects such as building a rocket, a roller coaster and a portal to mars, creating a one hit wonder and a clothing line and racing chariots. The projects, Ferb had to admit, while amazing and quite fun, were not exactly "street legal". Still, providence seemed to be on their side as all of Phineas and Ferb's projects disappeared as soon as they were done with them, taking a harsh toll on their sister's sanity.

"Good Morning, Ferb." Mom smiled as he came down the stairs. Ferb said nothing but smiled back at her. Mrs. Flynn-Fletcher took her stepson's silence in stride. She had learned many years ago when Ferb first came to live with them that it was nothing personal. Ferb rarely spoke to anyone. It wasn't that he was sullen or stupid; he simply didn't have a lot to say.

"So what do you boys have planned today?" She asked.

"Nothing yet." Phineas said happily, "But we'll think of something, right, Ferb?"

Ferb nodded.

"You always do." Linda smiled. "Your father and I are going to the Antiquing convention in Millbrook. We'll be back around three."

"Okay." Phineas said. "Have a good time."

"Oh we will!" Ferb's Dad, Lawrence, came in through the living room. His eyes sparkled with excitement. "There's going a lecture on the carbon dating of ancient Chinese teacups!"

"Can't wait." Their mother gushed.

"Sound's cool." Phineas said. Ferb smiled slightly. His parents were interested in the strangest things but they were always happy. The family had been completed four years when Linda and Lawrence had finally tied the knot and settled in Danville. Six years ago, Ferb and his father had emigrated from the UK to America. In England, Lawrence Fletcher had been an archeologist but moved out of field work to take care of his son. America promised better job opportunities and after six months, it promised a new life as well. Linda Flynn and her old flame met again after twenty years and two marriages, starting right where they'd left off. It was a perfect love story, albeit with a rather long detour, and having spent most of his life as an only child Ferb found himself with two new siblings in addition to a new mother.

"Well we're off." Linda said, grabbing her purse. "You boys be good now."

Candace poked her head down the stairs. "You're leaving?" She asked. "I'm in charge, right? You told them I'm in charge, right?"

"Candace, nobody has to be 'in charge', you know." Her mother said exasperated.

"What if it's an emergency?" Candace demanded, coming down the stairs. "What if-?"

It was at this point that Ferb tuned out. Candace enjoyed the illusion of control. He supposed it didn't really matter who was 'in charge'. He and Phineas would do whatever popped into their minds first and Candace would inevitably try to bust them. The specifics were what kept his life interesting, the basic remained sound day after day. Candace meant well. She honestly loved and cared about both her brothers but she was a teenage girl and rather set on structure. Phineas and Ferb's projects disrupted her structure, making her even more panicked then the usual teenager. Ferb had hoped that her neurotic tendencies might ease just a bit since she finally started dating Jeremy Johnson, the boy she'd been obsessing over for the past year but alas, so long as Phineas remained dedicated to making each day worthwhile (by his own standards), Candace would continue to have panic attacks. Ferb didn't mind. It was fun to watch.

Candace finally talked her mother into conceding that she was in charge if any lives were threatened by the boy's actions or by acts of God. Satisfied, she poured herself a bowl of cereal and began to text her friend Stacy. Ferb finished his own cereal and saw that Phineas was waiting for him.

"Come on, Ferb." Phineas smiled. "Let's go sit under the tree in the back yard. Ferb nodded and followed his brother. In the hallway, they were accompanied by Perry, their pet platypus. As Phineas was fond of repeating, Perry the platypus didn't do much but he was a good pet. He was there, most of the time, when you needed him.

"So." Phineas asked as they sat down together on the grass beneath the tree, "What do you want to do today?"

Ferb shrugged. He didn't really care. Phineas made most of the decisions for the two of them. He was better at ideas. Only a few months younger, Phineas was his best friend and closest brother. What Phineas could think of, Ferb could build. He was no slouch at mechanics himself but Phineas was better at finding causes and projects, like the time they'd gotten an '80's rock band back together for their parent's anniversary or built a haunted house to cure their friend Isabella's hiccups. Ferb relished Phineas's schemes, they made his life so much more interesting. Phineas cared deeply about things and took action to make things better. When they'd first met, Phineas was the only one who didn't find Ferb's reticence disturbing. They didn't need any time to get used to each other. All they needed for friendship was to know each other.

"We could start a zoo." Phineas suggested. "Or maybe build an old timey soda shop? Any ideas, Ferb?"

Ferb sat back against the tree and thought. There was no hurry. They had all the time in the world.

Candace Flynn chatted away happily on her cell phone. Jeremy, her Boyfriend!, was telling her about his new job as a manager at Slushi-Burger. He was really big time now, making more than minimum wage. This meant he took ample opportunity to shower her with beautiful boyfriend/girlfriend gifts.

"Yeah, Jeremy, you were so totally sweet to send me those flowers!" She gushed. "Yeah, African Violets are my favorite! How did you know?"

Jeremy could have gotten her a bag of crabgrass and it would have been her favorite.

"So, hey, it's my day off…" She could almost hear his super dreamy smile over the phone, "You wanna hang out?"

"Sure, Jeremy, always!" Candace grinned. Today was going to be fantastic. "I'll just get my bike and head to your house."

"Actually…" Jeremy said uneasily, "Do you mind if we hang out at your house. My mom decided to do some remolding and there's stucco everywhere."

"Sure…" It was Candace's turn to be uneasy, "but don't you wanna go to the park or the movies or something?"

"Well, whatever you want to do, Candace," Jeremy said. "But I was kind of looking forward to hang out with you, just the two of us."

"Eheheheheheh." Candace giggled happily. "Okay, Jeremy."

"Great!" He said. "I'll be over in a little."

"Bye, Jeremy."

"See you in a bit."

They hung up and Candace leaned back on the couch and sighed. It was going to be a perfect day! The sun was shining. The birds were singing. Jeremy was coming over to "hang out" with her "just the two" of them! Phineas and Ferb were being quiet! Candace narrowed her eyes. "Too quiet." She muttered, rising and heading to the backyard. "If those two ruin my day with Jeremy, I'll- I'll- I'll bust them so hard they won't be able to see straight!"

"You two!" She shouted approaching the boys in their usual spot under the tree, "What are you doing?"

"Well, nothing yet." Phineas said. "We can't decide. It's either start a zoo or invent a new sport. What do you think?"

"Look, I don't care what you do, just stop it!" She said. "Jeremy is coming over in a bit and if you two mess it up for me with one of your little projects I'm gonna call Mom and you're gonna be sooo busted!" She stormed away. Phineas looked at Ferb.

"Mom and Dad don't believe in over medication, do they?"

"Unfortunately, no." Ferb told him.

"Pity." Phineas said. "Hey, where's Perry?"

The platypus was nowhere to be seen. "Hey, maybe that's what we should do today…" Phineas said. "Figure out where Perry disappears to all day."

Ferb shook his head.

"Yeah, you're right. He's a platypus; they don't do much." Phineas stood and walked inside. "Thinking's thirsty work, Hunh? You want anything?"

Ferb shook his head.

"Okay. Try figure out what we should do." Phineas slipped into the kitchen. Candace sat at the kitchen table, talking to her friend Stacy.

"I'm telling you, Stace, they're up to something. I just don't know what." She paused, listening to Stacy's input. "Yeah totally. I don't know why they can't be like normal kids with a lemonade stand or something."

Phineas grinned and ducked out into the back yard. "Ferb!" He shouted. "I know what we're gonna do today!"

Ferb looked up.

"We're gonna build a lemonade stand." Phineas said. "The biggest, most impressive, tricked out lemonade stand in the whole tri-state area! Go get your tools!"

Ferb nodded and got his tool box.

In the kitchen, Candace glared out the window. "Well, Ferb's getting his tool box, Stacy. It's only a matter of time now… No, I'm not obsessing too much! We're sixteen, there's no such thing!"

The doorbell rang and Candace shrieked. "I gotta go, Stacy! It's Jeremy!"

She raced through the kitchen and living room and swung the front door open. "Jeremy!" She grinned. "It's so good to-" Candace stopped short as she took the time to look at the person standing in her door way. "You're not Jeremy."

"No." The woman spoke in a posh British accent. She was tall with short spiked green hair and brown eyes. Her clothes, jeans and a dark blue hoodie, were the only normal thing about her. At her sides were two large men wearing police uniforms. Candace was immediately suspicious. This had Phineas and Ferb written all over it.

"Who are you?" Candace asked.

"My name is Katrina Ingleside, formerly Fletcher." She smiled. "You are Candace Flynn, I presume. Is your stepfather at home?"

"Fletcher?" Candace stared at the woman. She nodded.

"I'm Ferb's mother."

"Could you just wait here for a bit?" Candace said and closed the door before the woman could answer. Surreptitiously, she glanced out the window. The woman bared little resemblance to her quiet younger brother, except for the green hair. Candace had never given much thought to the former Mrs. Fletcher. She'd assumed, like her own father, Ferb's biological mother had died. Dad had never mentioned Ferb's biological mother before and Ferb hardly mentioned anything at all. Still, if this woman was really Ferb's biological mother, Candace was sure that Dad would have told them she was going. She reached for her cell phone and quickly dialed her own mother's phone number.

"Yeah, hi, Candace." Her mother answered with an already exasperated tone. "Whatever the boys are doing, I'm sure it's not as bad as you think."

"No, Mom, it's not the boys this time." Candace said.

"That's new." Her mother's tone softened. "Well, is it an emergency because I'm driving right now and I don't want to have an accident."

"Mom, there's this weird British woman here" Candace whispered into the phone. "and she says she's Ferb's mother."

"What?" Linda exclaimed.

"I don't know. She just showed up on the doorstep with a couple of cops and she says she's Ferb's mother. She's got green hair." She added as an afterthought.

"Candace, stay right there." Her mother commanded. "We're coming home. Did this woman tell you her name?"

"Katrina Ingleside." Candace glanced out the window. "How long until you get here?"

"About twenty minutes." Linda told her. "I'm turning around now. Candace, do not let her in until we get there."

"Okay."

"And keep the boys out of sight." She told her.

"Why?" Candace demanded, suddenly getting very worried. "What's wrong with this woman? Is it dangerous?"

"Candace, I've got to go. We'll be there as soon as we can, until then, you're in charge. I love you. Good bye."

"Bye, Mom." Candace knew she was speaking to dead air. Her mother had hung up. The meaning of her words began to sink in, "You're in charge." Candace knew she was only ever to be in charge when there was an emergency. The arrival of Katrina apparently signaled an emergency.

Not five minutes had passed before her phone rang again. It was her father. "Candace!" He started before she could say hello. "Is everything alright?"

"Yeah." Candace said, startled. "I mean, nothing's changed really?"

"Is Katrina still there?"

Candace looked out the window. The woman was glancing around at the house and the neighborhood. She didn't seem at all agitated by her abandonment. Rather a cool smile played across her lips as she took in her surroundings.

"Yeah, she's outside. Dad, what's going on?"

"I'll explain later." He said hurriedly. "Where are the boys?"

"Out back, building something." She hadn't even had the opportunity to figure out what yet. The morning had changed from serene to panicked so quickly.

"Get them inside. Quickly."

"But-"

"Candace, listen to me!" He had never spoken so harshly to her. "Get the boys inside now! It is imperitive that Katrina does not see them and that they do not see her! Do you understand?"

"Yes." Candace said, even though she didn't.

"Good. Now go quickly." He hung up without saying goodbye. Candace hurried to the back yard.

The boys were already building something. It was a building about two stories high. Phineas was signing a few waivers while Ferb was welding some sort of machine together.

"Phineas, what are you doing?" She demanded, momentarily forgetting her mission.

"Oh. Hi, Candace." He turned to her with a naïve smile. "We're building a lemonade stand."

"You guys need to come inside right now." Candace said before he could go into further explination.

Ferb turned off his welding gear and looked at her. "Why?" Phineas asked, also staring at her.

"Um…" Though Dad had not specifically told her to hid the woman's existence from her brothers, Candace was fairly certain that was what he wanted. "It's going to rain."

"The skies are clear." Phineas pointed out. "And the roof is almost done."

Ferb nodded.

"Look, I'm in charge and if I say it's going to rain, it's going to rain!" Candace grabbed each of them by the wrists. "Now get inside."

"Wow." Phineas starred at her, allowing himself to be dragged toward the house. "Is it an emergency?"

"I geuss so." Candace muttered.

She managed to get them inside with little resistance. Phineas and Ferb were easy enough to control when faced with a direct order. Candace looked at the front door. She could still see the unwanted visitors' shadows. The main problem would be keeping her brothers out of sight until their parents came home.

"Okay." She said, trying to figure out what to do. "Go upstairs and don't come down until I tell you, okay?"

"Candace, what's going on?" Phineas asked, looking a little worried.

"Just go upstairs, both of you." Candace told him.

"Okay." Phineas shrugged and started toward the staircase. "Hey, there's somebody at the door."

"Yeah, I know." Candace said. "Now get upstairs!"

"Okay, okay, we're going." Phineas said. As her brothers climbed the stairs, Candace's phone began to ring.

"Oh please be mom." She prayed as she picked up.

"Hello?"

"Candace?" It was Jeremy. "Are you home? I rang your doorbell and nobody answered."

"Jeremy!" She gasped. She'd compleately forgotten about him.

"Yeah, hey do you know there are two cops out here?"

"Yeah, I know." Candace rushed to the door and opened it. Jeremy stood next to Katrina Ingleside who was still patiently waiting with a calm smile on her face. "Come in." She said to Jeremy.

"Candace, what's going on?" Jeremy asked, walking past the threshold. "You seem flustered."

"It's been quite a morning." Candace said, feeling much better now that Jeremy was there. He was always so safe and comforting, with that calm dependable look on his face as though he were ready for anything.

"Candace, if it's going to rain, I'll need my toolbox." Ferb's voice on the stairs brought her out of her Jeremy filled bliss.

"Ferb-" she began but was cut short by another voice.

"Ferb?" It was Katrina Ingleside's posh British accent that spoke his name. Candace turned on her. The smile had been wiped from her face, replaced with a look of deep concentration. Her brown eyes were fixed on Ferb. He stared back at her, his face expressionless. After a few minutes, he spoke.

"Mother?"

Well, that was fun, was it not? Reviews are awesome.
