A/N: Well, hello again my lovelies. I know you're out there, I can see my hit counter going up. Ok, so headcanon time (which will explain some parts of the story so far.) I see PnF as homeschooled kids. I think Candace may have been early on, but insisted on going to public high school. I think the boys may have tried mainstream school one year or so, but were both bored to tears, so their parents took their education in hand. In my personal canon, they both received their diplomas at 15/16 (it is possible, if you work at it, and they are both very smart, creative, and persistent.) I think from 16-18 they either started a business, took commissions (such as the amusement park and Ferb's upcoming apartment complex,) or both. They work together during the week inventing new gadgets and do their own thing on weekends. Yes, we will find out who Phin's escort was, later in the story. I'm still aiming for 10-12 chapters, I don't want to drag this one on too long, or I won't finish it.

A/N 2: Next chapter, this story will earn that M rating. There will be lemons. Forewarned is forearmed, right?

Ferb pulled back from Her, cutting off the kiss and attempted to stifle his yawn. He was very glad he didn't have to work the next day, as far as he knew. Phineas had an annoying tendency to come up with last minute plans.

"You know how much I'm enjoying this, Isa," Ferb stated quietly, running his hands up her arms to rest on her shoulders. He could see the goose flesh rising on her arms as he did so, and the thought he could make her have such a reaction made him feel powerful.

"Yea, me too, but we both really need sleep. I guess I should head home." Isabella replied, shifting off him and laying down on the bed, facing him. The separation chilled her skin, making her shiver slightly. Ferb pulled his duvet over her.

"No, it's too late, and you're too sleepy," Ferb replied as he watched her stifle yet another yawn, and resisted the urge to do so himself. He gave her a soft peck on the forehead before he stood and rummaged through his closet, coming up with a fleece blanket. "Get some rest, I'll be across the hall if you need anything."

Isabella only hummed in response; she had already faded off into dreamland.

In the early hours of the next morning, Phineas let himself into his parents' house, and set about making some toast for himself. He knew there were plenty of things he could accomplish today, but for the moment all he really wanted was food in his belly and his warm bed.

After downing his toast and a half glass of orange juice, Phineas made his way upstairs to his room, only to be surprised to find his brother fast asleep in his bed and gently snoring, Perry curled up at his feet. Not wanting to disturb either, he shrugged and made his way across the hall to his brother's room, briefly wondering why Ferb was in his bed in the first place. His question was answered by the sight before him in Ferb's bed, causing one brow to raise in curiosity. Well, he supposed he now knew why Isabella hadn't come back to the hotel room after her shift. Ultimately, that had been a good thing, Phineas thought to himself, as his escort had not left til almost dawn. The two meeting would have put all of them in a highly awkward situation. Phineas made his way back down the stairs and collapsed on the couch, managing to pull the throw halfway over him before he nodded off.

Later that morning, after seeing his wife off to her knitting class, if Lawrence Fletcher was surprised at the new sleeping arrangements in his house, he didn't let on. Instead, he gently tucked a blanket around Phineas, then set about making extra pancakes for their house guest, happy in the knowledge that he and Linda had raised two gentlemen.

Isabella knew something wasn't quite right about her surroundings when she slowly awoke to the smell of maple syrup and Ferb's shampoo. She groaned, rubbed her eyes and stretched, then sat up in the bed she found herself in. After a cursory glance down to discover that she was indeed still in her work clothes from the evening before, sans sandals, she finally got out of Ferb's bed and made her way to the restroom to answer nature's call.

After finishing her morning ablutions, Isabella made her way to the Flynn-Fletcher's kitchen, with a quick pit stop to put her shoes on. She found Lawrence flipping one last pancake onto a large stack while humming to himself.

"Good morning, Mr. Fletcher," she yawned as she took a stack of plates from him.

"Good morning, Isabella," he smiled in return. "Did you have to work last night?"

"Yes, Ferb was nice enough to come pick me up. I guess I fell asleep and he didn't want to wake me," she replied as she pulled her phone out of her purse. She was glad to see that there was only one missed call from her mother, from roughly thirty minutes previously. She tapped the number and put the phone to her ear as she stepped out of the sliding glass door into the back yard.

"Hola, mi hija," her mother said without preamble. "Where are you?"

"Across the street, mami. Ferb picked me up from work this morning and I guess I crashed on him."

"Uh-huh," Vivian Garcia-Shapiro replied doubtfully, "I hope you used protection, Isa."

"Mama!" Isabella wasn't sure whether to shout or laugh at her mother. "As if Ferb would ever take advantage of me!" especially considering everyone thinks I'm in love with Phineas, Isabella added silently to herself. Was she still in love with Phineas? She shoved that thought to the back of her mind for now, she could mull over it in private later. "He was a perfect gentleman, if the pile of blankets on the couch is anything to go by."

"Well, I'm glad to hear it. I would like to be una abuela someday, but it doesn't have to be that soon!" Vivian laughed as Isabella blushed slightly and groaned in reply before saying her farewell and putting the phone in her pocket.

When she entered the kitchen, she found a bleary-eyed Phineas at the table, shoveling syrup-coated pancakes into his mouth. Isabella was a bit taken off guard, she'd always assumed that Phineas was a morning person; that he bounded out of his bed first thing in the morning chatty and ready to invent. Of course, she knew that he'd also had a long night. Before she could wonder where Ferb was, she could hear the squeaking of the upstairs shower being turned on, answering her question. The thought of showers made her realize she was still in the clothes she'd been wearing the night before, and her hair could probably stand to be washed. Not wanting to be rude, she helped herself to two pancakes and hurriedly ate them, wanting to get home and take a long, hot shower. Thanking Lawrence for the lovely breakfast, Isabella slipped out of the back door again, this time to head across the street to her own house. She waved at and blew a kiss to her mother, who was pulling out of the driveway on her way to work, then headed up the stairs to her own shower and bed.

Ferb finished his shower and dressed quickly, his stomach growling at him ferociously. He'd slept harder than he had thought he would, considering he never slept well in strange beds. Shrugging the thought off, as Phineas' bed was hardly strange to him, he made his way downstairs just in time to see Isabella thank his dad for breakfast and walk out the back door.

Ferb found himself slightly bothered by the fact that Isabella hadn't waited for him to come downstairs. He'd wanted to tell her goodbye, possibly walk her home, see if the feelings that had so suddenly overcome her the night before were still in tact, or was she using him as a rebound man.

Mulling over the situation as he spread butter and poured syrup over his flapjacks before proceeding to cut then into even triangle-sized eighths, Ferb wondered what had happened the night before. When he'd watched the couple leave in their taxi the previous evening, they had seemed happy enough, if a little tense. He'd chalked that up to first date nerves. What had gone wrong? Apparently, Isabella had gotten over any lingering feelings for his brother quickly enough. Something was off, though, Ferb just couldn't put his finger on what.

Knowing how long it had taken him to move past his crush on Vanessa, and actually be happy for her in any relationship she chose to have, he thought Isabella's change of heart seemed conveniently rapid. Determining to speak with her before the end of the day and attempt to ferret out her true feelings, he finished his breakfast, tidily wiping his plate clean with his last triangle. He put his plate in the sink, gave his father a quick one-armed hug and waved at his brother before heading back upstairs to gather his things before heading for City Hall.
