A/N: Thank you everyone who's read, reviewed, followed and added to favourites from the first chapter :D

Age: 15 still, a week after the first chapter

Disclaimer: I don't own Phineas...Nigellus- for he was the least popular headmaster at Hogwarts in history. Also, he was a free man. Like Dobby is a free elf. Speaking of, I don't own anything to do with Harry Potter, or Phineas and Ferb for that matter.


Phineas and the Nefarious Knee of Doom

"You're sure about this?" Isabella asked Phineas as she followed him into his room and closed to the door behind her.

It had been a week since the 'incident'- they were calling it- one week since they'd argued over a film and made up outside his garage.

(One week since Phineas had been a lot more concerned than usual with how much exercise he doesn't do.)

"I said I would." He smiled as he took the DVD case off her and knelt in front of his TV.

"Actually, I believe you said you'd watch them all in one sitting if it would keep me happy." She giggled as she sat down in the corner of his bed and took her jacket off.

"Didn't I say 'I'd sit them all out now if it means you'll keep smiling at me like that,' or something to that effect?" He asked her and straightened, realising he'd just said it out loud again.

I know what you said. I just wanted to hear you say it again.

"So you did." She finally responded as he took and seat on his bed against his headboard.

"You can sit back here, you know. I don't bite." He joked as he lifted his pillows from the space next to him and placed them against the head board. He looked up as she stood waiting for him to finish and his eyes landed on the door.

Damn it she closed the door! How am I going to open it without her knowing?

"No! Don't sit yet!" His voice came out in a strangled yell as he jumped up.

"What? Why not?" Isabella asked him, alarmed at his unusual behaviour.

"Because," he began as he walked over to his closed door and opened it wide, "because it's kind of stuffy in here, isn't it? We could do with a through breeze." He finished as he walked over to his window next and threw it open.

"Um, yeah. That would be nice." Isabella responded as he turned to face her.

I should have gone to the bathroom and then left the door open when I came back. Brilliant Phineas, think of a good plan after you've looked like an idiot.

Oh my God. He's blushing. His parents must have told him to keep his door open because I'm in here!

Phineas cleared his throat loudly after what felt like a minute of staring and said "So...do you want anything before we start? A drink? Popcorn?"

"No, I'm good thanks, your mum gave me some drinks, remember?"

"Aha, yeah. So she did." He laughed, scratched the back of his head and frowned.

Why does this feel so awkward today? We were just fine yesterday!

Oh yeah, she knows my parents don't trust me in a room alone with her.

"Shall we sit then?" She asked him, giving him a concerned look.

Ten minutes later they were both thankfully settled next to each other, drinks in hand, absolutely not touching.

"That's the um, house-elf, right?"

"Right."

"You don't like it when I talk through these films, do you?" Phineas grinned at her and she smiled back.

"I'll allow it, if you keep smiling at me like that." Her smile turned into a playful smirk.

"No need to tease me now, is there?"

I meant it- and oh my- he's blushing again! Calm down Isabella, just stay calm.

Do not under any circumstance drift to Phineas Land! Drift...on those beautifully deep blue eyes and-

"Ha! The way he says 'George'. George." Phineas repeated, unknowingly snapping Isabella out of her fast approaching day dream. "Hang on! That's not what happens in the book! The twins are supposed to pick the lock and go fetch his stuff from the cupboard under the stairs!"

"Phineas, as thankful as I am that you remember what's in those books, like all movies adapted from books, the film always skips and changes some parts." Isabella explained.

Phineas stayed quiet after Isabella said that, only opening his mouth once to say "Oh come on, what about the de-gnoming?" To which Isabella had simply shrugged.

"At least they kept the flying car." He said dejectedly.

"I had a feeling you'd like that part." Isabella smirked, both remembering Phineas' own success at making a flying car.

They sat in silence until Isabella let out a laugh at the boy currently dangling from an open car door.

"What was funny? He almost died!" Phineas said incredulously, staring at her.

"I don't know, it's just the way he says Ron's hands are sweaty! It always makes me giggle." Isabella said, interrupting herself by said giggles.

Phineas rounded on her. "You think sweaty palms are funny, do you?"

"Um...no?" Isabella answered cautiously, unsure why his tone had suddenly changed.

"Do you think those poor, poor people that are doomed to live their lives with clammy hands...is funny?!"

"Phineas-what?"

"'Ol' Clammy Hands', I bet they're called!" Phineas drastically yelled as Isabella started to giggle again.

"Clammy Anderson!" He continued with even more drama now, flourishing his hands wildly as he continued.

"Clammy Anderson the Third, I bet! The poor guy has had to deal with generations of shame AND YOU LAUGH AT HIS MISFORTUNE?!"

Isabella erupted into fits of laughter at this, and only laughed harder when Phineas looked more enraged.

"SHAME!" Phineas yelled, pointing at her with as much force as he could muster. "Shame on you and your family! And as your punishment, I will hold onto your hand until mine is as clammy as Ron's. Clammier, if I can manage it!" Phineas insisted and made to grab her hand, though Isabella put up a fight, now shrieking with laughter.

"Gross, Phineas! They're already so wet!"

"Well, Isabella, it's warm in here," Phineas reasoned in a suddenly calmer voice, "and pointing so dramatically really takes some energy, but this is the lesson you have to learn! Soon, there will be an ocean in there, and you'll just have to sit there and take it!" Phineas finished victoriously, lacing their fingers tightly so she had no choice but to sit by and accept it.

As gross as this is, holding hands with you isn't a massive punishment.

This is-this is gross. Why am I subjecting her to my own clammy palms?

"Ok, I've accepted my punishment- ("Good!") –but I now have a request."

"No, you can't try and air it out, not until you learn your lesson."

"No," Isabella started, but then had to pause because she had started laughing again, "Can we get on with watching the movie? We've missed at least 20 minutes!"

Phineas moaned. "We've missed the tree, haven't we? I'll get the flicker and..."He drifted off, looking between the remote he'd left at the end of his bed just out of reach, and very discreetly at his hand currently holding Isabella's.

"...and I already know what happens, so why don't we just leave it?" He said with a smile.

He was looking at our hands! He didn't get the remote because he didn't want to let go! Argh! I can't wait to tell Gretchen about this! She already knows he holds my hand sometimes, OK, we hold each other's hand and that's AWESOME, but now he's doing it while we're watching a film!

Alone.

In his room.

ON HIS BED.

Breathe, Isabella, breathe. There is the slight possibility that he won't find it attractive when you hyperventilate.

Not that he'd notice anyway.

Isabella stole a sideways glance at him as discreetly as she could, and fought tooth and nail to keep a grin from breaking out when she discovered him doing the same. They both looked away within a second.

On second thought, maybe he would- and damn it- I've not been paying attention. Where are we? The girls' bathroom?! I've missed half the movie!

Just as Isabella forcibly re-amerced herself in the film, Phineas suddenly let go of her hand. She didn't have time to question whether her 'punishment' was over till he saw his mum knock on the open door and walk in.

"You kids OK? Want anything? Snacks?" Mrs Flynn-Fletcher asked them sweetly.

No, Mum, thanks for obviously checking on us, though.

"No thanks, Mum, Isabella?" Phineas asked, looking at her.

"I'm good, thanks Mrs Flynn-Fletcher." Isabella said, raising her only half drunken glass.

"Alrightey then, I'll leave you two to your film night." She said, made to grab the door but then remembered what she'd told Phineas. Her hand hovered for a moment before she waved at the last second and left to go downstairs again.

"That was nice of your mum." Isabella said after a minute of silence. She ached to hold Phineas' hand again, clammy or not. She fought the urge by pulling her legs up to her chest and hugging her knees.

"Yeah it was- are you cold or something?" Phineas asked, having just seen her movements.

"What? No, I'm fine." Isabella responded quickly, smiling, and relaxed as she sat cross legged instead.

Phineas felt as if he should have been given a medal for fighting off that flinch. Her knee was just millimetres away from his outstretched leg.

She's going to know I how hot I'm getting though her stupid knee again!

How can I move away without offending her? Good, Phineas. Think before you act stupid this time, you're getting the hang of this.

"Oh, I always love seeing the chamber!" Isabella gushed happily, breaking Phineas' train of thought momentarily.

...Knees aren't even stupid.

It's just a knee.

Her knee.

Which she's using against me because apparently testing poor old Phineas is number 1 on her list of Fun Things to Do!...Oh wow, she's right. Look at how beautiful that is! The production team must be proud of themselves when they see this!

Phineas, drawn by his sudden interest in how they possibly made such a magnificent room for a film, threw his attention back into the film in time to see a backfired memory charm.

"Well, serves him right." Phineas said and Isabella hummed in agreement.

"Honestly, all those women in the books falling all over him, it's just ridiculous!"

"Ridikulous?" Isabella asked, turning towards him with a grin.

"No, rid-ic-u-lous." Phineas said, sounding out each syllable of the word, but faltered when he saw her smile turn into an expectant frown.

"You mean- you mean 'Ridikulous' like, "This class is ridiculous," don't you?" Phineas asked her and was overjoyed that he'd remembered and that her smile was back in place. He knew watching these films with her would be worth it.

"Five points to Gryffindor." Isabella said quietly and Phineas laughed.

"But like I was saying, come on, would you fall for someone who looked so perfect on paper?"

You're kidding me, right?

"I mean, there was obviously something wrong with him! There always is with someone as perfect and handsome as that!"

"So what's your flaw?" Isabella asked before she could stop herself.

"I- what?"

"I just mean," Isabella stammered out, her heart going a mile a minute as it hammered painfully in her throat, "You're, you know, perfect as well. On paper."

Phineas looked thoughtful for a moment. "No more perfect than you." He said calmly, which seemed even calmer compared to the array of emotions and colours that flew across Isabella's face.

"I see you didn't mention anything about my looks though!" Phineas suddenly said, and without waiting for her to respond, said "It's my hair, isn't it?" And grabbed a fistful of his red hair, leaning closer to Isabella.

"No need to show me!" Isabella cried, immediately putting on a British accent, "Red hair, and a hand-me-down robe," She grabbed at the collar of the jacket he was wearing, somehow not noticing his sudden dark red blush, "you must be a Weasley!"


Woodland5: Thank you, as always for your review. I'm happy you found that line funny, and super glad you are a fellow HP fan :D


Wasn't sure how to end this chapter, but it was getting pretty long, so I ended it where it is and it feels OK to me.

Oh, and if anyone has anything they'd like to see in these chapters, like parts from the movies they'd think would be fun to include, feel free to let me know :D
