Disclaimer: I do not own Adventure Time.

Hey guyz! I am sorry for the long wait, but I've been really sick for the last few days. The worst was yesterday, so I think I am past it now.

Anyway, this is another chaptetr! More Finn and PB, Jake and Marceline, a little of Jake and Lady, and out of request from Soloeater and 10do, you get an apperance from the cornpups! Enjoy.

This is Chapter 5

Princess Bubblegum opened up the curtains to her bedroom as the sunlight of the next morning shined through. She was still somewhat tired mainly because of the constant tossing and turning in her sleep from the last few days. Her brain just couldn't rest as so many things, many Finn-related, kept popping in her mind. As a result, she figured she probably wouldn't get anymore sleep so, she took a quick shower, quickly put on her experimenting clothes and was off to her lab. Strangely, her lab door was slightly cracked. "Science thieves…." PB thought as she took a look through the crack. Unfortunately, the crack was big enough for to see anything, so she readied herself for what might behind the door and swiftly opened it, only to be startled by Finn, who was calmly sitting at a table, playing with her rat, Science.

"Hey Princess." Finn waved nonchalantly not noticing PB somewhat paler complexion and wide eyes.

"Finn! Whatever are you doing here?! This early?!" PB exclaimed, hand over her chest, catching her breath.

Finn replied innocently "Well I couldn't sleep, so I thought I could just pal around with someone. Luckily, your rat, Science, happily obliged."

"How did you even get in here? I always lock my lab before I went to bed last night." PB questioned.

"Peppermint Butler let me in. I guess I woke him up while I was strollin around here, so he just let me into the lab." Finn figured. PB sighed "Well I guess since you're already here, we might as well get started."

PB set up the Aura Visualizer and connected it to Finn. She then had him stand in front of the optic lens. What she saw was Finn's usual aura. The only abnormality was that there was a small black dot circling around. She made note of it but wrote down beside it "Probably nothing" .

"Finn, there's nothing terribly wrong with your aura, but just to make sure, I'm going to be checking it every day for this next week." PB explained. Finn nodded curtly. PB was about to turn to her other experiments but suddenly remembered "Oh, I have to take a look at his family's time machine to at least get an idea of what scientifically might have happened. This is going to be fairly awkward, but it must be done." PB then nervously said "Finn…?"

"Yeah Princess?" Finn replied.

"The cell activity test equipment won't be ready until tomorrow and I have no other tests to perform on you for today." PB began calmly.

"Okay….?" Finn replied in a go on tone.

So, uhh, I-II know it m-mmight be too ss-sssoon to ask this but…." PB stammered as she tried to ask her question as gently as possible. Finn looked at her questioningly, pondering the reason for her weird behavior "But what?"

"Would it be alright if, you and I, went to your family's house? I would like to take a gander at your Uncle's time machine. I kinda wanted a look so then I can scientifically figure out what happened to you." PB quickly explained her reasoning, expecting the worst reaction from Finn. Nonetheless, she looked him dead on.

"Yeah, it's cool. I've been wanting to get back there and check out some more of my dad and uncle's things anyhow." Finn replied coolly. PB sighed in relief, noticing that she had been holding her breath, waiting for Finn's answer.

"But how are we supposed get there, if nobody other than Pepp But, you and Jake are allowed to see me?" Finn questioned. PB responded nonchalantly "Oh no worries about that. I have a few disguises you can wear, that will disguise you." Finn nodded. "TO THE DIGUISE ROOM!" PB exclaimed pointing in its direction.

In the disguise room, Finn was having trouble picking a disguise. There were probably 100 or so different ones in there, but a lot of them were for girls, gross, and most of the boy ones didn't appeal to him. He knew he couldn't be too obvious because he was the only known human in the Land of Ooo and if people saw through his disguise, they would think there was another human and it would just be a big mess. He continued to look through disguises but none really caught his eye.

"Princess, not to be, you know rude or anything, but these disguises are horrible. None of them are good enough to confuse people or cool enough to be something an adventurer would wear." Finn sighed as he took an overview of the disguises again.

PB replied "I'm sorry, Finn. But you need a disguise that will make you look like a simpleton who's just out with me on a walk. Not an adventurer. That would call too much attention to yourself."

Finn sighed. He looked through again and found a Banana Guard costume "I guess, I'll wear this then. I mean it'll just look like you wanted to investigate something and decided to take a Banana Guard to be safe." PB nodded in agreement "That's perfect." Finn quickly put the disguise on over his clothes. He gave her a thumbs up sign as the two left the room to leave the castle.

"Will I be able to take it off when we get there?" Finn whined slightly as they made it to the castle door. "Well, of course, Finn. It's your house after all." PB responded softly.

"It is my house isn't it? I haven't even thought of that. Been too distracted…." Finn thought as he leisurely side-glanced at PB. He mentally sighed. As PB closed the door behind them, she whispered to Finn "We should test out your disguise on the candy citizens, to make sure its believable." Finn nodded.

As they strolled through the candy streets to the entrance of the Candy Kingdom, other than a few quick hellos to Princess Bubblegum, the candy citizens hadn't really interacted with the pair, as they left Candy Kingdom. "Phew! Well, if you fool them you probably could fool most." PB said as she wiped sweat off her forehead. She motioned for Finn to lead the way and he complied.

Jake woke up beside a sleeping Lady, while his new cornpups sweetly dreamed on, directly below him. He sighed to himself. "Glad I got here last night, or else I wouldn't have seen the birth of my pups!" He quickly went downstairs to make his one and only and their children some breakfast, knowing they would wake soon. He used Mom's manual to make French toast. Sunlight broke through the windows as morning settled in, waking everyone up and bringing the house to life. Jake noticed that his children looked somewhat bigger than the night before. Nevertheless, he set the table, putting each one of his kids custom made bowls in their rightful spaces "Charlie… T.V. … Viola… Kim Kil Whan… and Jake Jr."

"Kids come eat!" Jake exclaimed. Just as all of the kids sat in their proper seats, Marceline came through the ceiling "Hey Jake, Lady. Oh hello you cute little puppies."

"Marceline, you can't just barge in Lady's house like that!" Jake said trying to intimidate Marceline. Marceline casually moved over to a picture on a wall and revealed her trademark sign "M", proving that she could randomly appear here if she wanted to. Jake looked down with narrowed eyes and muttered "Why'd you have to be 1000 years old. Jeez."

"What are you doing here anyway?" Jake asked somewhat annoyed.

" Well I came here to talk to you about those two weeks you wanted to wait?" Marceline responded. Jake nodded suspiciously "Yeah….?"

"Well I got bored of waiting. So I'm gonna go over there to spy on them. You don't have to if you don't want to, you got responsibilities here." Marceline said as she motioned to the pups who were chowing down on their dad's awesome French toast. She flew away shortly after that.

Jake looked helplessly at his wife, who knew the reason why no one could see Finn, and asked "Could I go with her? Just for a little while, you know, to make sure she doesn't find anything weird." Lady quickly nodded and told him for 1 hour. He quickly grew/stretched to 25x his actual size and ran, catching up to Marceline within a couple minutes. Marceline casually looked down at the oversized dog, smirking, knowing he would come. She looked back up, as they made their way to Candy Kingdom.

PB and Finn had gone a little ways on their journey when they heard distant voices behind them. PB quickly turned around to see if they had followers but there wasn't any. Finn ventured a little bit back, peeking out of a bush, they had just passed. He spotted Jake and Marceline as they charged to the Candy Kingdom. He whispered to PB "It's Jake and Marceline. They're going to the Candy Kingdom. They might see us. What do we do?"

"We hide behind this bush. And you will have to look out every few seconds to see if they have gone because if I checked, Marceline would recognize me right away." PB answered. They quickly jumped behind the bush, out of view from Marceline and Jake.

As Jake was running, he saw a distant pink flash which was followed by the rustle of a distant bush. He thought "PB….?" He looked up at Marceline to see if she saw it too. Luckily, she was too excited about reaching the Kingdom to notice. Jake mentally sighed. They two slowed down as they entered their destination.

Since Marceline wasn't too crazy about mingling with the candy citizens, she had Jake ask where PB was. All of them said that PB had left for the morning, not knowing where exactly though. Mr. Cupcake, as he flashed his muscles to Marceline, causing her to chuckle, specifically said to ask Peppermint Butler since he was left in charge. So, the two ventured to Princess Bubblegum's humble abode, the castle, in which Peppermint Butler had been standing outside.

"Yo, little PB." Jake greeted

"Hello, Jake. Marceline…" Peppermint Butler started warmly, but grew sour when he saw Marceline.

"Butler." Marceline replied stand-offish. A moment of a mix of anger and awkwardness occurred between the three. Jake broke the silence "Well, we came to ask about PB."

Peppermint Butler answered "Okay, I'll tell you whatever you want Jake. But not in her presence." He looked at Marceline in sheer disgust. Marceline exclaimed "Fine! I'll just wait outside this rinky-dunk Kingdom, for Jake then." She left. Jake pondered on what exactly could have happened between PB and Marceline to make even Peppermint Butler hate her. Then he asked "It doesn't seem like PB and Finn are here. So where did they go?"

"I apologize Jake, but the Princess didn't share these details with me. She just ordered that I watch over the kingdom until her and Sir Finn returned." Peppermint Butler said.

Jake snapped his fingers "Shoot. I'm gonna have to tell Marceline something so she will leave them alone. Thanks anyway Peppermint Butler." He walked away, leaving Candy Kingdom and sitting by Marceline who had been tuning her bass. "So what did the nub say?" Marceline said, not taking her eyes off her bass. "Well he said that Finn and Princess Bubblegum needed to go get some items from another princess so they could continue with the experiment." Jake nervously lied.

"Really, which princess?" Marceline replied slightly curious.

Jake responded "Uhhh, well before I answer that, and this a completely unrelated question but which princess do you least like?"

"Well, I don't really like that purple- lump chick. I don't know her name. She's talks weird and she's gets crazy mad over little things. I think her outbursts are hilarious though" Marceline replied.

"Oh, that's Lumpy-Space Princess. That's actually the princess they went to see. And there's only one way to get to lumpy-space and that's through her so…." Jake stated.

"Oh well. I guess we can just wait another week like you said." Marceline sighed as she packed up her bass. "See ya later Jake." She flew away. When she was far away enough for Jake not to see her, Jake fell to the ground, exhausted. He sighed "This keeping big Finn a secret thing is wearing me out." He trudged back to Lady's house.

PB and Finn had finally made it to Mystery Kingdom. Other than the slight scare of being found by Marceline, they hadn't had any trouble getting there. As soon as they got past the entrance, PB screeched "Oh GLOB! I'm sinking in mud!"

"Oh yeah, I forgot to tell you about that." Finn guilty answered. PB glared at him but nonetheless followed him until they reached his home. She was amazed by the house's plainness. To her, for people who were so smart, you would expect more extravaganza. But that wasn't the case here.

"Yeah I know, it looks really plain, but you should see the basement. It's way cooler." Finn said as he motioned for her to follow him downstairs. As they reached the bottom step and Finn turned on the lights, Princess Bubblegum was taken aback. The extremely large room was filled with a variety of inventions! All leading to the biggest of them all, which she deduced was the time machine. She followed Finn to it. Finn gently touched his uncle's time machine thinking of how long and hard he and his father must have worked on it. PB's eyes softened. She had never seen Finn so vulnerable. She noticed that as Finn touched it, the fingerprints he left glowed blue. Suddenly, a deep male voice similar to current Finn's was heard and a video emerged from the center of the enormous device. It started small but the soon filled the entirety of the semi-circle of metal that was the time machine.

PB gazed as she saw a fairly well-dressed, handsome man sitting on an armchair come into view. Finn let PB watch the video while he went play with one of his uncle's inventions. He didn't want PB to see him cry again, just in case he did. She continued to watch as the video panned to what looked like Finn's uncle's clone, with his hands wrapped around a gorgeous woman. Her eyes began to brim with tears as she thought of how beautiful and courageous the sacrifice Finn's family had done for Finn truly was.

PB was so enthralled by Finn's family; she hadn't noticed an electrode quickly shoot out from the time machine. Finn immediately recognized it and ran towards her.

"NOOOOOOOOOOOOOOOOO!"

A/N: Well we still got Marceline trying to find out what Finn and PB are doing. At least she'll leave them alone for another week though. Speaking of PB and Finn, did Finn save PB from turning into an old lady?! Well if you keep reading, you'll for sure find out.

For you FinnxPB fans out there, you might be on a roller-coaster of your own next chapter. ;) ;)

Until the next,

Spazzy
