I've decided to create a collection of fluffy vignettes in the Fletcher-Flynn Foundation timeline. Expect fluff, and romance, and more fluff, and nothing higher than a T rating.

The Narbonic/Skin Horse crossover is being annoying, and this little thing popped into my head and decided it needed to be written. We haven't checked in on the Fletcher-Flynn Foundation timeline in a while, so have some Phinbella fluff.

Timeline: early spring semester, Phineas and Isabella's senior year of college. About a year and a half after their wedding.

Phineas sat at the kitchen table, taking a quick break from his thermodynamics homework, and looked down at the ring on his left hand. A simple band of yellow gold with a wave of white gold in the center, it did not look like much, but it signified...everything.

He shook his head and looked over at the couch of the large apartment he and his wife shared with his brother and sister-in-law. Isabella was curled in one corner of the couch, reading a book on her tablet. If he looked closely, he could see her ring, a matched twin to his own, glinting on her finger.

As if feeling his eyes on her, she looked up at him and smiled. "What?" she asked.

"Just wondering what I did to deserve someone as wonderful as you in my life."

She put her finger to her lips in thought. "Hm, that's a tough one. Invented hundreds of cool things over several summers to keep your friends and family entertained."

"Drove my sister crazy as she tried to bust me for doing reckless things that could have gotten me or one of said friends killed if they'd gone wrong," he countered.

"Helped anyone who asked you for help - especially me, when I needed help with Fireside Girls patches."

"Gave you an unfair advantage in getting patches compared to anyone else. And completely overshadowed what you'd done when I helped my sister get fifty patches in one day."

Her brow furrowed a bit. "Saved my mother's life, and then gave the technology you used for it to the world to save more lives. Which it has."

He smiled. "And then got rewarded with research funding to get you - and me - and Ferb through college together."

She set the tablet aside, stood up, and walked over to him. Sitting in his lap and lacing her arms around his neck, she asked, "There's nothing that says you can't get multiple rewards, Phineas. Your intentions have always been good. So have the results. But this isn't really what's eating you, is it?"

He shook his head, his arms resting around her waist. "No. We're graduating soon. Everyone is expecting incredible things out of us. Out of me. What if...it doesn't happen? What if I never do anything else? We've got that massive lab under construction back in Danville; how are we going to pay for it? It's a lot of responsibility - I've got a wife counting on me, and my brother and his wife too, and maybe someday kids of our own..."

"Then somebody else comes up with our next big idea. Ferb, or Vanessa, or even me. There's plenty of things that you guys did that could become real science. The teleporters, maybe, or the antigrav boots. Those are closer to real science than miniaturization was. Vanessa's got as much of a physics background as you do, now - her dissertation work dropped the energy costs for miniaturization by a third, remember."

"And what if that isn't enough?"

Isabella brushed a hand forward along his cheek. "Then we get real jobs. It's not like it's done Candace or Jeremy any harm, and they've got a kid to take care of and twins on the way. Candace loves her job as a family therapist, and Jeremy seems to be enjoying being a music teacher." She took his face within her hands, forcing him to look at her. "Phineas Garcia-Flynn, you are not allowed to mope about this. As long as we're together, we can get through anything."

He smiled; they'd merged names a year and a half ago at the wedding, but it still made him happy to hear it. "Not allowed, eh? What are you going to do to stop me?"

She leaned in and kissed him, murmuring, "I'll find a way," against his lips.
