Disclaimer: I don't own Phineas and Ferb or Phineas and Ferb: Across the 2nd Dimension! I do own this storyline though!

Phineas was baffled by what he had just mumbled. Do I really love her? I mean, she IS my best friend... maybe I just love her as a friend. No, that can't be it. I've never felt this way about a person before.

"Phineas? Are you okay?" Isabella whispered, shaking the boy out of his trance.

"Wh-uh... yeah, I'm fine! Ready?" he asked, letting go of her hand. She glanced down at their hands and slightly frowned, but hid it when she looked back up at him. She wondered if he could see her exact reactions through these masks, but then saw that Phineas' mask clearly showed his facial expressions. Well, I still have to be careful to hide my emotions even though I have a mask on.

She nodded, and the two started down the street. All of a sudden, their earpieces beeped, indicating that there was a message. Candace's voice came through.

"Okay, you two. In order to reach the portal, you have to go to Charlene's mansion. It's on the other side of town, so you have quite a bit of walking to do. Go down Maple Drive, turn left on Banner Street, then go down the alley directly to your right. It's going to take you down to a pothole just like the one you came through, and keep walking to the end. The next pothole opening will be in front of her mansion. Call in when you get to this point. DO NOT- I REPEAT DO NOT go in without a plan."

Isabella shuddered at what they had to do, but just kept walking. Phineas pressed his earpiece and replied with, "Copy that."

"So... what should we talk about while we walk?" Isabella asked, looking over at Phineas, who was staring at the ground deep in thought. "Phineas?"

He jolted from his daydream at the mention of his name. "Huh? Oh. I don't know, what do you wanna talk about?"

Isabella looked at him concerned. "You're not okay," were the words that came out of her mouth, unexpectedly.

"Um... excuse me?" he asked, raising an eyebrow.

Isabella finally snapped. "You're not okay! I can see it on your face. You're usually the loudest person in the group. Ever since you started 'remembering' things, you've acted like someone died. Please tell me what's going on."

Phineas looked at her, stopping. He was irritated with everything and just wanted to get it all off of his chest. He ripped off his mask to talk to her for a minute, and she took the cue and took hers off as well. "You know what? I'm NOT okay. I just got a huge burden put on me. I have to keep you safe while making sure you don't remember anything of what happened. It's hard! It's like I'm living in a nightmare and I can't wake up from it." Phineas started, but then words started to spill out of his mouth without thinking.

"And now, I'm confused because I can't figure out my feelings about you. I don't know what to think anymore. It's like I have this obligation to make sure nothing happens to you, and I can't even tell you what I want to tell you the most. I want to share the best day of my life with you, but I don't want to have to forget it all again." Phineas said, and then started to tear up. He covered his face with his hands and sat down on the ground in front of a light pole.

Isabella stood in shock for a minute, trying to process everything he had just said. After processing, she pieced together a response. "Phineas, you don't need to feel obligated to keep me safe. I'm a Fireside Girl, I can handle myself! As for remembering things, I'm not sure what happened, but I can tell it's hurting you. I'd love for you to tell me everything about the best day of your life. I don't care if we have to get our minds erased, I'm there for you through everything. You're my best friend, Phineas Flynn." She said, but still couldn't figure out what to say about the 'figuring out my feelings' part.

Phineas had just been hit with the fact that he had told her he was 'figuring out his feelings' about her. Stupid, stupid stupid! You just confessed you might have feelings for her, and now she's gonna think you're a creep. He then listened to her response, and those feelings of self-loathing melted away.

"Isabella... are you sure? I don't want you to stress about it as much as I have been. Besides, it's been making me feel super queasy and sick lately, and I don't want you to go through that too." he asked, referring to her wanting him to tell her about the day he had remembered.

"I'm 1oo% positive. I'm always here for you." she smiled, sitting next to him. She put her hands under her legs, slowly swaying side to side.

He looked at her, tears still in his eyes. "I don't deserve you..." he said, a small smile spreading across his face. He couldn't take it anymore. He pulled her in for a warm embrace, wrapping his arms around her tightly. She grinned and hugged him back. Maybe this is the day he's going to tell me how he feels!

A beep came on their earpieces, scaring them out of the hug.

"Why haven't you two moved in 5 minutes? You're not gonna make it by sunset! Get moving, soldiers!" Candace shouted, causing them to flinch and cover their ears, which didn't do much.

"Shut up! We were having a moment!" Isabella replied angrily.

"Do you want a moment or to get home? And don't tell me to shut up! I am your superior!"

Isabella grumbled and the two kept walking.

Phineas looked at her and beamed. "Wanna hear about the whole day you forgot about?" He looked a lot happier now that he had vented all of his frustrations.

"Go for it!" Isabella grinned.

"So at the beginning of the day, we built a platypult and got shot up into this purple building, and there was this pharmacist building a portal, and Ferb and I helped him fix it, and Perry showed up and peed on his couch, and then we went through, and-and there was a copy of the pharmacist but he had an eye patch, and then- and then Perry's a secret agent! And so I was mad at him, and he gave me this pamphlet as we were gliding down on his hang glider, and I was like 'No, I don't want your pamphlet!' and I threw it, and then-"

Isabella stopped him. "Did you say Perry is a secret agent?"

"Yeah! We're not supposed to know. So, it has to stay between us two, you can't tell ANYONE or they will take Perry away from us." Phineas said urgently.

"Oh! Wow..." Isabella said, thinking of the story he was telling. It was weirder than any of their previous adventures, but Phineas was so enthusiastic about it, and he had so much character, practically acting out the day. She couldn't help but blush at him, he was just so cute when he acted like this. This was the Phineas Flynn she fell in love with. Not just into this situation with, but truly in LOVE with.

They laughed and they cried at all of the things that had happened in a single day, and then Phineas reached the brain-wiping scene.

"And just as they were about to press the button, you-" he stopped and his eyes widened. He had practically forgotten that that had happened, with everything else going on.

Isabella was intrigued. "I did what?"

"You... do you really want to know?" he asked, his face turning bright red.

"Yes! Tell me, tell me! Did I save someone? Did I smack Buford in the face? I've always wanted to do that. What did I do, Phineas?! Tell me!" she giggled.

Phineas found this an opportunity to tell her how he really felt. He felt a smirk emerge on his face. "You REALLY wanna know?"

"Don't torture me! Tell me!"

Phineas had finally figured out how he felt about Isabella. I'm not letting her go this time. I'm going to do this. He was about to confess how he felt, but decided against it as a better idea popped into his head.

"You know, it was just such an amazing experience that I'm not gonna tell you until we get back home. I guess you're just going to have to wait and see!" he winked and raised his eyebrows.

Her face dropped. "Phineas Flynn, you did not just bait me. Just TELL ME! Pleeeeeassee?" she asked, the last part with a puppy dog face.

He was tempted to tell her right then and there, but he closed his eyes. "Nope! Not falling for that! I'll tell you when we get home! Just gives us an incentive to work faster!" he chuckled and slipped on his mask again before climbing up the ladder to get to the pothole.

She groaned in annoyance but put her mask on and followed him up the ladder.

Phineas' stopped at the top and pushed the pothole lid off with a grunt. It clattered on the asphalt above, and Isabella gasped and almost fell off from shock.

Phineas heard her gasp and looked down over his shoulder. "You okay down there?" he asked.

"Yeah! Fine! Just startled me a little bit." she laughed nervously and continued to climb the ladder as Phineas made sure no cars were coming and then pulled himself out, leaning over to help her out. She looked up to see him looking straight at her and blushed as he extended his hand for her to take.

She took his hand and he pulled her out, causing him to stumble backwards and onto the pavement, taking her with him. She fell on top of him, and he stopped breathing when he realized that she was directly above him. Isabella opened her eyes to find him staring at her as she moved a strand of hair out of her face.

He didn't want to move. She looked absolutely stunning in the slowly fading sunlight, then gasped when she realized what had just happened. She gasped and jumped off of him.

"I'm so sorry, Phineas! Are you okay?" she asked him, as he laid completely still, unmoving from the laying down position. "Phineas?"

He sat up slowly, still looking at her. "Y-yeah... I'm fine! Ready to go?" he asked, hopping up and looking up at the towering pink building. He called in on his earpiece.

"Candace, we're here... now what?" he asked nervously, his cheeks still red from the unsuspected awkward moment before.

"Okay... to get in, you're going to need your mask. We knew that there is an identity scrutinizer, so we made a special mask especially for this. Look in your backpack, you will find a small package. There is a button on it, and Phineas, you're going to need to put on the mask. It's got traces of DNA that will allow you in. Once you get in, put on your own mask and costume and try your best to blend in with the rest of the servers. I'm right here, I'll be guiding you through what to do. Isabella, just put on your own mask right now."

Phineas nodded as if he was talking to someone who was there right now and slung his backpack off of his shoulder. He dug through and found a small box. "Aha! Got it!" he said, pressing the button, opening the box and revealing a mask that unfolded. He slipped it over his head and it fit surprisingly snug. He looked over at Isabella, who had just put on her own mask, and when she saw him, she let out a giggle. He grinned and walked towards the garage door looking opening, stopping near a metal box with a hand imprint.

"Oh! There's a glove in the box as well! You need that for the hand part!" Candace exclaimed, and Phineas pulled out the backpack again, slipping on the glove. He hesitantly put his gloved hand on the screen, and it scanned his eye and hand and then beeped, flipping to show a few metal instruments, that moved to his face. Phineas jumped back, and the instruments followed him, one grabbing his tongue, one going in his ear, and then the instruments retreated back into their places. When the door didn't open, he raised an eyebrow in confusion. "Now what, Candace?" he asked.

"Now, this is the funny part. Isabella, get ready to laugh. Phineas, walk over to the door, and turn around." she snickered.

Phineas turned around confusedly as a flap opened and scanned near his rear end. He gasped and his head shot around his shoulder. "Why is it scanning THAT?" Phineas asked out loud, causing Isabella to start cry laughing.

After the scrutinizer finished scanning every tiny detail, Phineas, feeling utterly violated, walked in, quickly swapping his mask and taking the glove off, and shoved the two into his backpack.

"Watch the mask! We need that for the future, Phineas!" Candace screamed, and Phineas jumped, pulling the glove and mask out and carefully folding them back into the box.

"Better?" he whisper yelled, zipping up his backpack. Isabella walked up behind him, and looked in awe at all of the trinkets and luxurious items that were stocked in the house.

"Good. Now, you're going to need to find the portal room. Unfortunately, it's right outside Vanessa's bedroom. It might take you a lot of quiet and patience, but you'll get there. Before you do that, you're going to need to find one of Charlene's household helpers and get them to show you the way. I've only been in there once, so I am not sure of the whereabouts of the portal. I've only been in Charlene's living quarters. Good luck you two, I hope you can make it home safely. This is the last I can help you with, from here you're really on your own.

How was that? Sorry for the delay on Phinabella, but I gotta keep the story going! Also, I'd like to give a shoutout to a new friend of mine that has been helping me edit and come up with new ideas, LionHeartDoxa! Go check out his story too, it's really awesome! Happy reading!
