In the kitchen of the Flynn-Fletcher house, Linda & K were talking when a familiar bespectacled man walked in.

"Hello dear, who's your guest?" Lawrence asked.

"This is my old college roommate, Katherine Bond" Linda explained "Kath, this is my husband, Lawrence Fletcher. He's from England, just like you are."

"Really?" Lawrence asked, quite intrigued "that's delightful; I don't see too many people from the old country. What did you do there?"

"You could say I took out the trash" K replied.

"Ah sanitation, fine line of work."

"Honey, we were just reminiscing about the old days" Linda explained "Kath here was quite the wild one; sometimes, she'd be gone for hours, then come back with no explanation. I remember one time, she came back smelling like gunpowder."

"Yes well, I had a little accident in the science lab that day" K covered "and besides, I was away at classes most of the day."

"I don't remember seeing you."

"My classes were, um, at the other end of the school, yes, that's right."

"Well, that sounds perfectly logical" Linda replied "who's for tea?"

In the meantime, outside the house, Phineas and Ferb were supervising the distribution of cheese.

"Isabella and her Fireside girls do good work" Phineas commented "Okay girls, a bit more cheese on the left side."

"You heard him girls" Isabella said, "increase cheese distribution."

Phineas then turned his attention to elsewhere "you guys got the toppings ready."

"All set, dinner bell" Buford said, setting down a large mushroom.

"Okay Ferb, let's get the big slicer ready" Phineas said. As his brother went off to prepare it, he noticed three kids he'd never seen before. "Oh hi, did you just move in?"

"Not really" Todd explained "are you guys, um, making a giant pizza?"

"Yup."

"And you made all this yourselves, without any help from your parents?"

"Pretty much" Phineas replied "if you'll excuse me, I need to get some giant pepperoni ready for slicing."

"Man, that is going to be one tasty pizza" Jacobo commented.

"Okay, am I the only one who finds it weird that these kids have the tools to build a giant pizza and giant toppings in their yard?" Todd asked.

"No, but you and your family have a spy car, with the lazers, and the missiles and the sarcastic quips that hurt my feelings" Shelton replied.

"Guys, I don't think you realize what this means" Todd explained "if these kids can build all this, imagine what else they could build. The world's largest video game system, a soda machine with every flavor ever, super fast go-karts! All we have to do is make a few casual suggestions, and we can have whatever we want."

"I don't know, that sounds pretty unethical" Jacobo replied.

"Yeah, it wouldn't be right for us to take advantage of the kids with their genius and the smarts" Shelton added.

"Look at it this way; it's not doing something wrong if it's kids building something for other kids" Todd explained "fate has clearly brought us here to ensure we get cool stuff. Are you two going to go against fate? Because that's suicide, man, that's…"

"Okay, we'll go along with you, just knock it off" Jacobo replied.

"Great" Todd said "now come on, we have a pizza to help make."

Meanwhile, inside the house, Candace was none to happy for several reasons. One was that she couldn't inform her mom of what her brothers were planning. The other was because she had to share her room.

"Hey, I want to thank you for letting me crash in your room" Riley said "I know this wasn't easy for you, us coming in uninvited and all."

"Okay listen up" Candace said curtly "I may be forced into sharing my room with you, but that doesn't mean I have to like it. So don't touch any of my stuff and we'll get along just fine, understand?"

"You know, it wouldn't hurt you to be a little nicer."

"I'm sorry. What's the proper way to act when someone comes out of the blue and is given part of your room? Am I supposed to throw you a parade or something?"

"Hey, I'm not any happier about these arrangements then you are" Riley said "I was supposed to be chilling in a hotel pool right now, but instead, I'm at the house of some old friend of my mom's I've never heard of, arguing with a mean, stuck-up teenager! If it wasn't for the award I'm receiving tomorrow, this trip would be a huge bust."

"I am not stuck-up!" Candace shouted "and anyway, I have bigger problems than you right now, so there!"

"Fine, I'll just sit here and read, if that's okay with you, oh great master" Riley said sarcastically.

"As long as you're not touching my stuff, I don't care" Candace replied, turning her attention to outside.

Riley reached into her suitcase and produced a book from it, sat down on the floor and began to read. Candace focused her attention away from the goings-on outside and towards her unwanted houseguest "what are you reading there, anyway?"

"Anne of Green Gables" Riley replied "it's about a very creative redheaded orphan who gets adopted by these complete strangers and adapts to life with a new family. I find I can really relate to the title character."

"Whatever" Candace scoffed, before turning her attention back out the window.

"What are you looking at?"

"It's none of your business, but my brothers are building a giant pizza outside, and I'm moments away from busting them, but I can't!"

"Doesn't sound like they're doing anything wrong. Why not drop it?"

"You don't know what I have to put up with every day from those two!" Candace said "it's always something new with them, like a teleporter, or a giant tree robot, or the rollercoaster."

"Sounds pretty impressive to me."

"Yeah well…you're not me."

"I think maybe you're just jealous you can't build cool things like that, so you take out your frustrations on them" Riley suggested.

"Mind your own business, Oprah."

Suddenly, Candace got an idea; "ooh, I'll take a picture and show it to mom! Then I'll have photo evidence. You two aren't gonna get away with it this time" she said. Quickly she dug around her room until she found a camera, then rushed off.

Riley ignored her and continued reading, but after a few minutes set down her book.

"Since I'm here, I should see what all the fuss is about" she said, also leaving the room.

Back on the lawn, Phineas had used a giant slicer to cut and distribute the pepperoni, and was now working on cutting some big mushrooms.

"Good job on these mushroom Baljeet" Phineas commented.

"It was nothing, thanks to some love. Oh, and of course, the special fertilizer you gave me."

Moments later, Candace came out, with her camera in hand.

"Hey Candace" Phineas waved from the controls of the slicer "have you come to take a picture for posterity? 'Cause we're not quite ready yet."

"Oh don't mind me" Candace said "take all the time you need."

"Wow! This is impressive!" Riley commented, looking over the pizza.

"Oh, hi there" Phineas said.

"Did you make all this yourself?" Riley asked.

"Well, I had some help from Ferb, he's my stepbrother. And of course, our friends. Say, are you with those new kids?"

"New kids? Oh, you must mean my brother Todd and his friends" Riley said "yes, I'm Riley Daring. My family and I are staying at your house for the night."

"Nice to meet you, I'm Phineas Flynn" the triangle-headed boy said "and that green haired kid over there is my brother Ferb. Say hi to our new friend Ferb."

From the other side of the lawn, where he was chopping onion, Ferb simply waved hello.

"He doesn't talk much" Phineas explained.

"I can't believe you built all this" Riley said "you must be pretty smart for a…how old are you anyway?"

Before Phineas could answer, Isabella quickly zoomed between them.

"So Phineas, are you going to introduce me to your new friend?"

"Oh sure. Isabella, this is Riley Daring; her family is staying with us for the night, or so she says. Riley, this is Isabella Garcia-Shapiro. She and her Fireside Girl troop are always a big help; I don't know what we'd do without them."

"Thank you Phineas, I…" Isabella began "wait, 'staying with us for the night?' You mean an older girl is going to be sleeping in your house?"

"Two older girls actually" Riley corrected her "my friend Tasumi is around here, somewhere."

"Oh, I see" Isabella said, trying to suppress her jealously "two older girls, sleeping in the same house as Phineas. Nothing wrong with that I guess. Um, if you'll excuse me, I have to go and do something."

"Okay, see you Isabella" Phineas said.

Once she was out of earshot, Isabella began to grumble. "'I can't believe you built all this'" she said mockingly "who does she think she is? She can't just come in from out of town and start admiring Phineas' brain! She's lucky I don't…"

The girl was roused from her ranting when she noticed Baljeet standing nearby, frozen in place.

"Baljeet, what happened? Did Buford give you a power wedgie again?"

"W-who is that?" Baljeet, asked, pointing towards Riley.

"Her? Oh that's just Miss big shot from out of town" Isabella said "her name's Riley I think."

"Riley. Ahh, what a beautiful name."

"Baljeet, are you crushing on that girl?"

"How could I not? Look at her Isabella, she is a paragon of beauty and grace. Oh, a boy wishes for a girl like that to come along, but once in a lifetime. And yet, I do not believe I could ever win her heart."

"'Paragon of beauty and grace?' You might be setting the bar a little too high on this…" suddenly, Isabella got an idea. "However, if you really like this girl, I'm sure I could help you woo her."

"You would do that for me?"

"Of course. As a girl, I understand what girls like, and want from a guy. With me helping you, Riley will almost certainly be yours. And, if that means she stays away from Phineas, well, then we both win."

In the next chapter, Isabella begins training Baljeet to help him woo Riley. Meanwhile, Agent P discovers an old foe of his has escaped and is up to no good, Todd makes a move to get stuff from Phineas & Ferb, and Candace & Riley discover how much they have in common and begin to bond.
