A/N: I realized that there weren't a lot of PhineasxFerb fics out there, so decided to write one of my own. I tried to keep it some what like the show itself, but taking into consideration that everyone is older in this story. Candace is probably about 21 , while Phineas and Ferb are probably around 16 and 17. Enjoy!

Gonna Be All Right

When I first realized they were together—loved each other that way—I was shocked. Shocked, appalled, and as much as I hate to say it, I was somewhat disgusted with it all. Brothers! Step brothers with no blood relation, but even still, they had grown up together. I couldn't—and still can't to a certain extent—wrap my mind around it.

All I knew was that my two younger brothers were holding hands and leaning toward each other when I had burst in that afternoon.

"Guys, I'm home! I'm home for the summer! Spring semester ended today!" I flew into the house, tossing all my college crap aside to be forgotten for a few months. Glancing around, I slapped my forehead like an idiot, suddenly remembering that mom and dad were in England.

'How convenient,' I thought to myself. 'The boys are probably out back building a damn space station or something.' Over the years, I had learned to calm my obsession with busting them, but I still hadn't given up on figuring out how the hell their inventions and projects always seemed to disappear.

And why Perry always did, for that matter. Where was he anyway?

Grabbing a pop from the fridge, I decided to take a look out back at the fabulous project of the day. Despite the fact that they were still in school—my spring semester ended in May, ha ha—those two somehow managed to whip something up quickly before dinner every night. I hummed to myself while I slipped on some flip-flops and opened the glass door.

"Hey! Phineas, Ferb! I'm home! What are you building tod—" My sentence was cut off. The yard was empty. That in itself was a miracle, but that wasn't what had caught my voice in my throat and made me drop my freshly opened Dr. Pepper.

Their hands were locked together, fingers entwined, and so close to each other that their lips were practically brushing. I only saw it for a split second, but there was no mistaking it. My two brothers had been about to kiss before I showed up. They flew apart, and Phineas waved at me, acting as though nothing had happened. His cheeks were red, though. As red as his hair. Ferb was silent and wearing an unreadable expression, like usual.

"Hey, Candace! You're back! Did your semester end today?" I nodded once, suddenly feeling a bubbly, cold sensation on my feet. The Dr. Pepper I had dropped. Perry crawled out of no where and began sucking it off of the pavement. "Oh, there you are, Perry!" Phineas said with a small laugh at his pet.

Finally, it sunk in, and I felt my left eye start to twitch.

"Phineas, what the hell!" I shouted, and kicked the can across the yard. Perry flinched a bit, but continued to suck up the sugary drink remaining. I felt like I was back in my old "busting mode" but this was a little different. I was just plain frazzled and confused instead of insanely set on a goal.

"Candace?" he asked, suddenly tensing up. He knew damn well what I was talking about, but seemed reluctant to address it.

"What the hell!" I repeated and clenched my fists. I shot my gaze to my other brother as well. "You too, Ferb! What the hell!" My British brother only blinked. Typical.

"Candace! Calm down! What's wrong?"

"Don't play dumb, Phin!" I said, jabbing a finger into his chest. He had grown so much in the past years. We were the same height now, and Ferb stood taller than both of us. "What was that? Why were you and Ferb about to—!" I sputtered and grasped a clump of my hair in my fist. Phineas' gaze was cast downward, like he was being scolded. Ferb remained where he stood a few steps away, eyes also downcast, but not like Phineas. Ferb looked as though he was expecting this to happen.

"Candace, Ferb and I are... well," He took a deep breath. "Ferb and I are together. We love each other. More than just brothers." My eye twitched again and my eyes frantically shot back and forth between the two. I felt like it had to be some sort of trick, some sort of malfunctioning creation they had made that day.

But no, it was my two little brothers. Standing before me, telling me they love each other more than normal brothers.

'Should,' I thought. 'More than normal brothers should.' Phineas was holding his ground, waiting for a response, but I could see how stiff he was. He was both wanting and dreading my answer. Ferb walked over slowly and took his brother's hand. They were both waiting now. Waiting for my answer to their... their insane statement!

"D-do mom or dad know?" I asked, my voice cracking a bit from the shock.

"No," Phineas answered. I swallowed, said action feeling like needles were sliding down my throat.

"Anyone else? Your friends?"

"No." Ferb answered this time, tightening his grip on Phineas' hand. I closed my eyes tight and I could practically feel my head starting to pound. I had just barely gotten over the stress of my final exams, only to come home and find out my brothers were... hell, my brothers were dating each other.

"I should keep quiet about this, then." My voice had dropped down to a whisper.

"We would appreciate it, Sis," Phineas said. I sighed again and slowly walked onto the grass before laying down on it. My hair fanned out beneath me, and I heard my brothers footsteps as they followed. Phineas sat down next to my head and Ferb sat down at my side.

"Candace," he said quietly, his accent still so noticeable after all the years in America. I looked over and up at them. Both looked slightly worried, as if they were afraid they had broken my brain.

"All right," I said in a defeated tone. "If I'm keeping this a secret, I should at least know what the hell this is. Tell me everything, you two."

Apparently, one night, Isabella had finally confessed to Phineas. She was usually such an out-going and strong girl, it really surprised me that it had taken her that long. After she confessed, Phineas said he had no idea how to respond to her.

"She's beautiful, Isabella is," he explained. "And an awesome friend. One of the best! But when she said she felt more than friendship, I had no idea how to react. She's wonderful, she really is. But for some reason, I couldn't return the feeling."

"But, Phineas," I interrupted. "You two were so obviously crushing on each other when you were young! What happened to you that changed that?" My brother shrugged.

"I have no idea," he said. "Maybe she waited too long."

"But that future that my future self came back to bust you from—"

"The future is never set in stone. It is always changing," Ferb explained. "That future we visited was one of the many possibilities. Your future self changed something from the past and created an entirely new set of events, leading to a different end result. I assume this somehow happened with Phineas and Isabella." I stared at him, slack-jawed. That was probably the most I had ever heard my step brother talk. Phineas cleared his throat, snapping me back to reality.

"OK, OK, so... the future isn't certain, Phineas and Isabella didn't end up together, but what the hell does any of this have to do with Ferb?" I asked, crossing my arms. The brothers looked at each other and back to me.

"Well, lets just say, even though I hadn't actually rejected Isabella, I wasn't doing so hot," Phineas said with a sigh. "I felt like a jerk, and was extremely confused why I didn't return her feelings. They had passed and moved on, without my even realizing they were gone.

"I came home a wreck. Shaking and all confused." He shrugged. "Ferb talked it all out with me." I eyed my step-brother curiously.

"I'm still confused how this is leading to you and Ferb becoming an item. Since when are you two gay? Ferb, you were always doing things 'for the ladies,' and Phineas," I said with a roll of the eyes. "Well, I guess you never really showed any interest besides Isabella, but still..." Phineas, surprisingly, chuckled at my words.

"Oh, Candace. Haven't you ever heard of being bi?" I slapped my palm to my forehead. This conversation was getting too weird for my taste, and as curious as I was, I had a feeling I didn't want to know how both my brothers had figured out that they fancied both genders.

"OK, OK, so you're both bi. Hunky dory. That still doesn't explain how you two got together!" I was getting impatient. I knew they weren't intentionally doing it, but it felt like Phineas and Ferb kept dodging the question. "I mean—Ahgh, Phineas, I hate to state the obvious, but you're brothers." He only nodded.

"Yeah, we know. But not related by blood."

"Well, yeah, but," I sputtered and rubbed my forehead again. "You two grew up together like real brothers even if you're not. How could you even think—?" Ferb cut me off.

"Candace, I know it might be weird, but Phineas and I saw each other more like best friends."

"Yeah, Sis, I mean, I understand that we had our brotherly moments, but think about it for a second. We never really fought or got really annoyed with one another like brothers—hell, siblings—usually do." I let out a groan and fell back into my original position lying on the grass.

"My brain hurts," I whispered. "You two and the things you do just go right over my head, you know that?" Phineas gave an apologetic smile and Ferb simply shrugged.

"If it makes you feel any better, Candace, we're still kinda figuring the whole thing out ourselves. Testing the water, so to speak." My younger brother patted my hand. "I guess you could say you walked in on one of our 'experiments,' per say."

"Just don't try to bust us on this one," Ferb added with a chuckle. I couldn't help but smile, even though the whole thing still confused me.

"OK, all crazy, new blossoming romances aside," I said after a long stretch of silence. "I am hungry. And I never got to drink any of my pop." Perry chattered his teeth and I sent him a glare.

"Sounds good," Phineas said and stood up, brushing himself off. "Where do you want to eat, Candace?"


"Well, you did just get home from college only to have your brain explode from Ferb and I's antics." He winked. "I think we owe you."

"God," I said with a grin. "When did you two get so sweet?"

"Since you started paying attention to us and not our inventions," Ferb answered with a smirk and held out his hand to help me up. "Now, choose a restaurant. We'll take you." I grabbed his hand and looked thoughtfully at the sky as he pulled me from the ground.

"You know what?" I giggled quietly. "Why don't you make a restaurant? A cool pizza parlor or something." They stared at me like I had gone completely crazy for a second. But then, Phineas absolutely beamed.

"Ferb, I know what we're gonna do today."

When I first realized they were together—loved each other that way—I was shocked. Shocked, appalled, and as much as I hate to say it, I was somewhat disgusted with it all. But the sounds outside of a construction site, seeing my little brothers wearing hard hats, and checking blue prints comforted me. Everything felt right in the world.

And as I watched them through the window, I saw them pick up where they had left off before I barged in on them. My two little brothers pressed their lips together in a soft kiss. I felt my eye twitch, but then they broke apart. Phineas saw me in the window and waved. His smile was brighter than any of those summer days when they had driven me up a wall, caused mom to question my sanity, or embarrass myself in front of Jeremy.

That image of them kissing each other so soft... So soft, with a giant pin-ball themed pizza parlor in our back yard, I realized it then. Everything felt more than right in the world. Everything was perfect.

"They're gonna be all right, Perry," I whispered, patting the platypus on the back. He chattered his teeth, and I knew he agreed. "They're gonna be all right."
